Efficacy of posterior fixation and bone graft fusion for treatment of lumbar brucellosis spondylitis.

The purpose of this study is to verify whether early stage patients with single-segment lumbar Brucella spondylitis can still be cured through simple posterior fixation and bone grafting, even without debridement. A retrospective study was conducted on 63 patients diagnosed with single-segment lumbar brucellosis spondylitis, who underwent posterior-only debridement (or not), bone grafting, and instrumentation from June 2016 to June 2019. Group A comprised 34 patients who did not undergo debridement, while group B comprised 29 patients who underwent debridement. The clinical data and imaging results of the patients were compared between the 2 groups to evaluate the clinical effects of debridement or not. Both groups of patients completed at least 1 year of follow-up. The group A had significantly lower values for operation time, blood loss, and hospital stay compared to the group B (P < .05). There were no significant differences between the 2 groups in terms of erythrocyte sedimentation rate, C-reactive protein, visual analogue scores, improvement of Japanese Orthopaedic Association Evaluation of treatment score, and Cobb angle. The bone fusion rate was 92% (31 patients) in group A and 96% (28 patients) in group B, with no significant difference between the 2 groups (P > .05). In summary, these findings suggest that posterior fixation and bone graft fusion are effective treatments for single-segment lumbar brucellosis spondylitis in early stages even without debridement. Importantly, these procedures offer several benefits, such as minimal trauma, short operation times, rapid postoperative recovery, and favorable bone graft fusion outcomes.

Comparison of two surgical interventions for lumbar brucella spondylitis in adults: a retrospective analysis.

This retrospective study aimed to compare the clinical efficacy of the posterior procedure with the combined anterior and posterior procedure in the surgical management of lumbar Brucella spondylitis. From January 2015 to June 2020, a total of 62 patients presenting with lumbar Brucella spondylitis underwent either one-stage posterior pedicle fixation, debridement, and interbody fusion (Group A, n = 33) or anterior debridement, bone grafting, and posterior instrumentation (Group B, n = 29). All patients were followed up for an average of 25.4 ± 1.5 months and achieved complete resolution of lumbar Brucella spondylitis. No significant differences between the groups were observed in terms of age or pre-operative, three-month postoperative and final follow-up indices of the VAS, ESR, CRP, lordosis angle, ODI scores, fusion time, and time of serum agglutination test conversion to negative (P > 0.05). Each patient exhibited notable improvements in neurological function, as assessed by the JOA score rating system. Group A demonstrated significantly shorter operative duration, intraoperative blood loss, and hospital stay compared to Group B (P < 0.05). Superficial wound infection was observed in one case in Group A, whereas Group B experienced one case each of intraoperative peritoneal rupture, postoperative ileus, iliac vein injury, and superficial wound infection. This study supports the efficacy of both surgical interventions in the treatment of lumbar Brucella spondylitis, with satisfactory outcomes. However, the posterior approach demonstrated advantages, including reduced surgical time, diminished blood loss, shorter hospital stays, and fewer perioperative complications. Consequently, the one-stage posterior pedicle fixation, debridement, and interbody fusion represent a superior treatment option.

Human descending aorta injury caused by brucellosis: A case report.

BACKGROUND: Brucellosis is one of the most common zoonotic diseases in the world. Although cardiovascular complications of human brucellosis account for only 3% of morbidity, they are the leading cause of death. Peripheral vascular disease due to brucellosis is rare and under-reported in the literature. CASE PRESENTATION: Two patients with previous brucellosis, both of whom had been treated with anti-brucellosis, were admitted to vascular surgery for thoracic aortic ulcer and abdominal aortic pseudoaneurysm, respectively, with positive IgG antibody to brucellosis and negative IgM antibody to brucellosis, tube agglutination test, and blood culture. These 2 patients were successfully treated with aortic stent-graft implantation and followed up for 8 and 10 weeks without complications. CONCLUSIONS: Chronic damage to human blood vessels by brucellosis may not disappear with brucellosis treatment, and peripheral blood vessels should be examined annually in people previously diagnosed with brucellosis. Clinicians in related departments should pay attention to peripheral vascular complications of brucellosis.

One-stage posterior surgery combined with anti-Brucella therapy in the management of lumbosacral brucellosis spondylitis: a retrospective study.

BACKGROUND: This study aimed to assess the clinical efficacy of one-stage posterior surgery combined with anti-Brucella therapy in the treatment of lumbosacral brucellosis spondylitis (LBS). METHODS: From June 2010 to June 2020, the clinical and radiographic data of patients with LBS treated by one-stage posterior surgery combined with anti-Brucella therapy were retrospectively analyzed. The visual analogue scale (VAS), Japanese Orthopaedic Association (JOA) and Oswestry Disability Index scores (ODI) were used to evaluate the clinical outcomes. Frankel's classification system was employed to access the initial and final neurologic function. Fusion of the bone grafting was classified by Bridwell's grading system. RESULTS: A total of 55 patients were included in this study with a mean postoperative follow-up time of 2.6 ± 0.8 years (range, 2 to 5). There were 40 males and 15 females with a mean age of 39.8 ± 14.7 years (range, 27 to 57). The Brucella agglutination test was ≥ 1:160 in all patients, but the blood culture was positive in 43 patients (78.1%). A statistical difference was observed in ESR, CRP, VAS, ODI, and JOA between preoperative and final follow-up (P < 0.05). Neurological function was significantly improved in 20 patients with preoperative neurological dysfunction after surgery. According to Bridwell's grading system, the fusion of bone grafting in 48 cases (87.2%) was defined as grade I, and grade II in 7 cases (12.7%). None of the infestation recurrences was observed. CONCLUSION: One-stage posterior surgery combined with anti-Brucella therapy was a practical method in the treatment of LBS with severe neurological compression and spinal sagittal imbalance.

Beneficial influence of single-stage posterior surgery for the treatment of lumbar brucella spondylitis combined with spondylolisthesis.

We aimed to evaluate the clinical efficacy of the single-stage posterior surgical treatment for patients of lumbar brucella spondylitis combined with spondylolisthesis. In this study, we performed a retrospective analysis of 16 patients with lumbar brucellosis spondylitis combined with spondylolisthesis from January 2015 to January 2019. All patients underwent single-stage posterior lumbar debridement, reduction, interbody fusion, and instrumentation. Preoperative and postoperative of the visual analog scale (VAS), the Oswestry disability index (ODI), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were compared. In addition, the spondylolisthesis reduction rate, reduction loss rate, interbody fusion rate, and complication rate were recorded. VAS, ODI, ESR, and CRP were conducted with repeated analysis of variance data at different follow-ups. The postoperative follow-up was 12-36 months, with an average of (25.0 ± 8.1) months. VAS, ODI, ESR, and CRP were significantly better at 2-week and 1-year follow-up than preoperative results (P = 0.000, respectively). In addition, 1 year after the operation, VAS, ODI, ESR, and CRP showed a significant improvement (P = 0.000, respectively). The average spondylolisthesis reduction in 2 weeks after operation was (91.2 ± 6.7)%, and the median reduction loss rate in 1 year after operation was 8.0 (5.0, 9.8)%. At the last follow-up, all patients achieved interbody fusion, no loosening and fracture of instrumentation were found, and no recurrence happened. Single-stage posterior operation for lumbar debridement, reduction, interbody fusion, and instrumentation is beneficial for treating lumbar brucellosis spondylitis combined with spondylolisthesis. Furthermore, the reconstruction of spinal stability may relieve pain, heal lesions, and improve patients' living.

Surgical management for lumbar brucella spondylitis: Posterior versus anterior approaches.

ABSTRACT: There has been no ideal surgical approach for lumbar brucella spondylitis (LBS). This study aims to compare clinical efficacy and safety of posterior versus anterior approaches for the treatment of LBS.From April 2005 to January 2015, a total of 27 adult patients with lumbar brucella spondylitis were recruited in this study. The patients were divided into 2 groups according to surgical approaches. Thirteen cases in group A underwent 1-stage anterior debridement, fusion, and fixation, and 14 cases in group B underwent posterior debridement, bone graft, and fixation. The clinical and surgical outcomes were compared in terms of operative time, intraoperative blood loss, hospitalizations, bony fusion time, complications, visual analog scale score, recovery of neurological function, deformity correction.Lumbar brucella spondylitis was cured, and the grafted bones were fused within 11 months in all cases. It was obviously that the operative time and intraoperative blood loss of group A were more than those of group B (P = .045, P = .009, respectively). Kyphotic deformity was signifcantly corrected in both groups after surgery; however, the correction rate was higher in group B than in group A (P = .043). There were no significant differences between the two groups in hospitalizations, bony fusion time, and visual analog scale score in the last follow-up (P = .055, P = .364, P = .125, respectively).Our results suggested that both anterior and posterior approaches can effectively cure lumbar brucella spondylitis. Nevertheless, posterior approach gives better kyphotic deformity correction, less surgical invasiveness, and less complications.

Safety and efficacy of polyetheretherketone (PEEK) cages in combination with one-stage posterior debridement and instrumentation in Lumbar Brucella Spondylitis.

OBJECTIVE: The aim of this study was to explore the efficacy and safety of surgical treatment of lumbar brucella spondylitis with PEEK cages combined with one-stage posterior debridement and instrumentation. METHODS: We performed a retrospective study for adult patients with lumbar brucella spondylitis. Medical records, imaging studies and laboratory data were collected, back pain was measured by employing the visual analog scale (VAS) and the neurological status was evaluated by using the American Spinal Injury Association (ASIA) scale. RESULTS: A total of 61 consecutive patients (42 males and 19 females) were enrolled with the mean age at presentation of 56.33 ±â€¯9.16 years old. L3-4 and L4-5 were the most infected levels with the ratios of 21.31 % and 19.67 % respectively. Moreover, 12 (19.67 %) patients suffered multiple-level infection and 5 (5/12, 41.67 %) of them had non-contiguous spondylitis. In addition, epidural masses were found in 26 (42.62 %) cases and psoas abscesses were found in 14 (22.95 %) cases. The number of operative segment depended on operation indications (failure of conservative measures, instability, kyphosis, intractable pain and/or neurological impairment). VAS scores were significantly improved at 6-weeks and the last follow-up. Among the 23 (37.70 %) patients with neurological deficits, 19 (19/23, 82.61 %) obtained a full recovery and 4 (4/23, 17.39 %) had been improved incompletely during the last follow-up. All patients exhibited satisfactory bone fusion during the last follow-up. Local infection of surgical site was identified in 6 (9.84 %) cases and no other surgery-related complications were found. CONCLUSION: Use of PEEK cages for interbody fusion is feasible and safe in patients suffering from lumbar brucella spondylitis.

Three Cases of Brucellar Spondylitis with Noncontiguous Multifocal Involvement.

BACKGROUND: Brucellosis is an endemic disease. Brucellar spondylitis is mainly manifested as a unifocal lesion, but noncontiguous multifocal brucellar spondylitis is more rare. CASE DESCRIPTION: Herein, we report 3 patients with noncontiguous multifocal involvement of brucellar spondylitis who are over 51 years of age. The diagnosis was established by using magnetic resonance imaging (MRI) and positive brucellar agglutination test. All patients were cured with antibrucellosis chemotherapy and surgery. For patients with a high degree of suspicion of noncontiguous multifocal brucellar spondylitis, especially elderly patients, screening with the use of serologic test for brucellosis and whole spine MRI is crucial to reduce the rate of misdiagnosis and missed diagnosis. CONCLUSIONS: Clinicians should raise awareness of noncontiguous multifocal brucellar spondylitis. The Wright agglutination test and whole spine MRI are the key methods to reduce misdiagnosis and missed diagnosis of noncontiguous multifocal brucellar spondylitis. Drug therapy for brucellar spondylitis is the basis, and surgical treatment is complementary therapy. The use of alternative chemotherapy and surgery for noncontiguous multifocal brucellar spondylitis is also safe and effective.

Flow-Diverter Stenting of Intracavernous Internal Carotid Artery Mycotic Aneurysm.

This is the first reported case in which a mycotic aneurysm refractory to the first medical treatment was treated with a Pipeline embolization device (PED), and the first case of a mycotic aneurysm from Brucella treated by endovascular therapy. A 35-year-old man presented with left eye pain and ptosis, and fever for 2 weeks. Before symptom onset, he visited Vietnam where he developed a flu-like illness; however, antibiotics were ineffective. We suspected Brucella as the most likely infectious etiology for the patient's intracavernous aneurysm. Since the aneurysm did not reduce in size following 2 weeks of antibiotic therapy, we placed a PED in the left internal carotid artery. Follow-up angiogram 4 months later showed no residual aneurysm, and cranial nerve palsies had completely resolved. From the results of this case, it appears that flow diverter stenting may be a safe and effective treatment of mycotic aneurysms of the cavernous segment of ICA.

The use of CaSO4 drug delivery system in transforaminal lumbar interbody fusion for spinal brucellosis.

OBJECTIVES: The incidence of human brucellosis has risen dramatically in China with few reports regarding the operation on spinal brucellosis. In this retrospective study we introduced CaSO4drug delivery system into the TLIF surgical procedure and evaluated its clinical effectiveness and feasibility. PATIENTS AND METHODS: 36 patients with lumbar brucellosis were enrolled and treated by posterior transforaminal decompression, instrumentation and fusion. Prepared CaSO4 beads carrying doxycycline were placed into the disc space and around pedicle screws. The activity of infection and pain-related function scales were recorded. Neurologic and functional recovery was evaluated using ASIA and Kirkaldy-Willis scale. Segmental and overall lordotic angles were measured and fusion status was assessed at final follow up. RESULTS: The average follow-up period was 15.6 ± 3.73 months. The level of ESR and CRP returned to normal at 3 months post-op. 14 patients with ASIA grade D pre-op returned ASIA grade E with 3 months. The improvement of VAS and ODI was 82% and 85.8% at 3 months post-op. The corrections of segmental and overall lordotic angle were 5.98 ± 3.54° and 6.24 ± 7.93°. 69% of patients reached definitive union at 12 months after surgery. The satisfactory rate on Kirkaldy-Willis functional outcome criteria was 88.9%. CONCLUSION: The use of CaSO4 drug delivery system during single-stage TLIF for spinal brucellosis was safe and showed no negative impacts on fusion status and neurological function recovery. Our results are promising and the drug delivery system may be considered as a choice for future treatment in spinal brucellosis or other spondylodiscitis.

One-stage surgical management for lumber brucella spondylitis with anterior debridement, autogenous graft, and instrumentation.

Literature reporting on lumber brucella spondylitis (LBS) is rare, therefore, the purpose of this study was to evaluate the outcomes of one-stage surgical management for lumber brucella spondylitis by anterior debridement, autogenous grafts, and instrumentation. This was a retrospective cohort study including 16 patients with lumber brucella spondylitis by treated from January 2009 to October 2011 in our department. All cases underwent one-stage anterior internal fixation, debridement, and bone fusion; clinical and radiographic results were analyzed and compared. All patients were followed up for an average of 35.3 ±â€Š8.1 months (range, 24-48 months). Brucella spondylitis was completely cured in all patients with bone fusion achieved in 4.8 ±â€Š1.3 months. Visual analog scale (VAS) scores were significantly improved between the preoperative and last follow-up visit and neurological function classification showed significant improvement after surgical intervention. Preoperatively, the Cobb angle was 20.7 ±â€Š9.8°, and measured 8.1 ±â€Š1.3° at the last follow-up visit. The outcomes of follow-up demonstrated that one-stage surgical treatment with anterior debridement, fusion, and instrumentation can be an effective and feasible treatment method for lumber brucella spondylitis.

Single-stage transforaminal decompression, debridement, interbody fusion, and posterior instrumentation for lumbosacral brucellosis.

BACKGROUND: Spinal brucellosis is a less commonly reported infectious spinal pathology. There are few reports regarding the surgical treatment of spinal brucellosis in existing literature. This retrospective study was conducted to determine the effectiveness of single-stage transforaminal decompression, debridement, interbody fusion, and posterior instrumentation for lumbosacral spinal brucellosis. METHODS: From February 2012 to April 2015, 32 consecutive patients (19 males and 13 females, mean age 53.7 ± 8.7) with lumbosacral brucellosis treated by transforaminal decompression, debridement, interbody fusion, and posterior instrumentation were enrolled. Medical records, imaging studies, laboratory data were collected and summarized. Surgical outcomes were evaluated based on visual analogue scale (VAS), Oswestry Disability Index (ODI) and Japanese Orthopaedic Association (JOA) scale. The changes in C-reactive protein (CRP) levels, erythrocyte sedimentation rate (ESR), clinical symptoms and complications were investigated. Graft fusion was evaluated using Bridwell grading criteria. RESULTS: The mean follow-up period was 24.9 ± 8.2 months. Back pain and radiating leg pain was relieved significantly in all patients after operation. No implant failures were observed in any patients. Wound infection was observed in two patients and sinus formation was observed in one patient. Solid bony fusion was achieved in 30 patients and the fusion rate was 93.8%. The levels of ESR and CRP were returned to normal by the end of three months' follow-up. VAS and ODI scores were significantly improved (P < 0.05). According to JOA score, surgical improvement was excellent in 22 cases (68.8%), good in 9 cases (28.1%), moderate in 1 case (3.1%) at the last follow-up. CONCLUSIONS: Single-stage transforaminal decompression, debridement, interbody fusion, and posterior instrumentation is an effective and safe approach for lumbosacral brucellosis.

Spinal epidural abscess caused by Brucella species: a review of 17 cases.

BACKGROUND: Spinal epidural abscess (SEA) is a rarely encountered clinical entity during the course of Brucella infection. METHODS: We reported 17 patients diagnosed with Brucellar SEA for a mean follow-up of 15 months. Spinal epidural abscess was detected by magnetic resonance imaging in all cases. Brucella diagnosis was established by serological tests. Patients were administered antibiotics for duration of 6 to 16 weeks. RESULTS: SEA was localized in lumbar region in 9 patients, thoracic in 4 patients, cervical in 3 patients, both thoracic and lumbar in 1 patient. Neurologic examination was normal in 4 patients, we detected motor and/or sensory deficit in 13 patients. Symptoms regressed in all patients after the institution of antibiotic regimens, and all recovered fully. Surgical drainage of abscess was performed in 2 patients and 3 patients were performed limited laminectomies. CONCLUSIONS: Antibiotic therapy could be primary treatment and is effective in required doses and duration for many patients. If neurologic deterioration be observed despite proper antibiotic regimens in required doses and duration, surgical intervention is to be performed.

One-stage Surgical Management for Lumbar Brucella Spondylitis by Posterior Debridement, Autogenous Bone Graft and Instrumentation: A Case Series of 24 Patients.

STUDY DESIGN: Clinical case series. OBJECTIVE: The aim of this study was to explore the efficacy and safety of one-stage debridement, autogenous bone graft, and instrumentation for lumbar brucella spondylitis (LBS) via a posterior approach. SUMMARY OF BACKGROUND DATA: Reports on LBS are sporadic, and the therapeutic effect and safety of surgical interventions have not been assessed in clinical studies. METHODS: Between January 2012 and January 2014, 24 consecutive patients with symptomatic LBS who underwent a one-stage operation that combined debridement, autogenous bone graft, and instrumentation via a posterior approach were enrolled. Back pain was measured using the visual analog scale (VAS). The neurological status was evaluated with the American Spinal Injury Association (ASIA) scale. Bone healing was evaluated based on postoperative plain x-ray or computed tomography. RESULTS: All cases were followed up for an average of 14.3 + 3.5 months. The VAS scores were significantly improved at every follow-up interval. An improvement of at least one grade level was observed in the ASIA score of each patient. The average time of bone fusion was 6.8 + 1.6 months. Significant improvements of the average segmental Cobb angle was observed from a preoperative value of 18.4° + 4.6° to a last follow-up value of 21.1°â€Š±â€Š3.7°. At the last follow up, the titers of antibodies against the standard tube agglutination test, erythrocyte sedimentation rate, and C-reactive protein were negative for all patients. CONCLUSION: For LBS, systemic antibrucellosis chemotherapy is the cornerstone of treatment. When cauda equine syndrome, radiculopathy, spinal instability, and severe back pain caused by extradural nonabsorbable abscess or progressive collapse are present, surgical intervention is inevitable. One-stage debridement, autogenous bone graft, and instrumentation via a posterior approach could represent an alternative treatment for LBS, and the efficacy and safety of these techniques are satisfactory. LEVEL OF EVIDENCE: 4.

Endovascular Management of Concomitant Thoracic and Abdominal Aortic Ruptures Resulting from Brucellosis Aortitis.

BACKGROUND: Acute aortic symptomatology is an unusual manifestation of Brucella melitensis infection. We present a rare case of acute multifocal thoracic and abdominal aortic ruptures arising from Brucellosis aortitis managed exclusively with endovascular surgery. METHODS: A 71-year-old Hispanic male with a history of atrial fibrillation and prior stroke on chronic anticoagulation presented with shortness of breath and malaise. In addition, he had been treated approximately 1 year previously in Mexico for B. melitensis bacteremia after eating fresh unpasteurized cheese. Computed tomography (CT) angiography demonstrated an acute rupture of the descending thoracic aorta just proximal to the celiac trunk and synchronous rupture at the abdominal aortic bifurctation. RESULTS: The patient was taken emergently to the hybrid operating room, where synchronous supraceliac thoracic aorta and abdominal aortoiliac stent grafts were deployed under local anesthesia. Completion angiography demonstrated total exclusion of the thoracic and abdominal extravasation with no evidence of endoleak. Twenty hours postoperatively, the patient became acutely obtunded and hypotensive. Repeat CT angiography demonstrated contrast extravasation at the level of the excluded aortic bifurcation. Emergent angiography confirmed a type II endoleak with free extraluminal rupture. Multiple coils were placed at the level of the aortic bifurcation between the left limb of the stent graft and the aortic wall to tamponade the endoleak. No further extravasation was noted on final aortography. Postoperatively, blood cultures confirmed the diagnosis of B. melitensis. The patient was treated with systemic doxycycline, gentamicin, and rifampin. Resolution of the acute event occurred without additional sequelae and he was discharged from the hospital to a rehabilitation facility. CONCLUSIONS: Concomitant multifocal aortic ruptures arising from Brucellosis aortic infection is a very rare event. In this case, the patient was successfully treated with thoracic and abdominal endovascular stent-graft exclusion, coiling, and long-term targeted antibiotics.

ENDOGENOUS ENDOPHTHALMITIS CAUSED BY BRUCELLA MELITENSIS.

PURPOSE: Brucella is an intracellular gram-negative pathogen that acts as a facultative parasite. B. Melitensis endogenous endophthalmitis is quite rare. We herein report an unusual case of B. melitensis endophthalmitis with a good outcome after appropriate management. METHODS: A retrospective interventional case report of an 18-year-old boy who had unexplained interrupted fever and malaise for the past 4 months and was being treated as a case of fever of unknown origin. He presented with a 10-day history of pain and loss of vision in the left eye. Visual acuity in the left eye at time of presentation was counting fingers near face. Extensive anterior chamber reaction and flare, as well as, vitritis were found on examination. All blood and urine investigations and radiological imaging were negative. RESULTS: A diagnostic/therapeutic vitrectomy with antibiotic injection helped in identifying the offending organism and controlling the inflammation. Vitrectomy sample revealed B. melitensis with no sensitive result. Patient recovered vision in his eye to 20/150. Eye examination revealed a quiet eye, with flat retina and some retinal pigment epithelial changes at macula. CONCLUSION: B. melitensis endophthalmitis is a rarely encountered disease entity. High suspicion and prompt management with vitrectomy and appropriate antibiotic injection was successful in salvaging the patient's eye.

Anesthetic and hemodynamic management of a rare case of Brucella multivalvular endocarditis in cardiogenic shock undergoing emergency aortic valve replacement and mitral valve repair.

We describe a very rare case of human brucella multivalvular endocarditis. Patient presented in a state of cardiogenic shock with low urine output and a history of breathlessness. Patient was diagnosed to have brucellosis 2 months back by blood cultures and agglutination tests and was receiving doxycycline and rifampicin therapy. Echocardiography showed severe aortic regurgitation, moderate mitral regurgitation, severe left ventricular dysfunction and a mobile vegetation attached to the aortic valve. Patient was scheduled for emergency surgery; while preparing for surgery hemodynamic monitoring, non-invasive ventilation and inotropic supports were started. During surgery, the aortic valve was found perforated and the aortomitral continuity was disrupted. Aortic valve replacement and mitral valve repair were performed. Hemofiltration was used during cardiopulmonary bypass. Weaning from bypass was achieved with the help of inodilators, dual chamber pacing and intra-aortic balloon pump.

Orchiectomy performed in two patients with brucella orchitis mimicking testicular tumour / Orquiectomía realizada en dos pacientes con orquitis brucelosa semejante a un tumor testicular

Brucellosis is a zoonosis caused by gram negative coccobacilli and it is an endemic infectious disease in Turkey. Infection is usually acquired as a result of direct contact with infected animals or by consuming milk or cheese freshly made from them. There exists a wide spectrum of clinical signs and symptoms in brucellosis. Many systems including musculoskeletal, gastrointestinal, cardiovascular and genitourinary may be involved in brucellosis. The genitourinary system is affected in 2% to 20% of the cases with brucellosis. The most common forms of brucellosis are epididymo-orchitis, testicular abscess and atrophy. The serum agglutination test to detect the presence of antibodies is a reliable test in patients with urogenital symptoms. Long-term and combined antibacterial therapy have been found to be effective in brucellosis. We present two cases undergoing orchiectomy because of testicular mass before the diagnosis ofbrucellosis was made.

La brucelosis es una zoonosis causada por cocobacilos gram negativos, y es una enfermedad infecciosa endémica en Turquía. La infección generalmente se adquiere como resultado del contacto directo con animales infectados o por consumo de leche o queso recién producidos a partir de ellos. Existe un amplio espectro de signos y síntomas clínicos de la brucelosis. Muchos sistemas, incluyendo los sistemas musculoesquelético, cardiovascular, gastrointestinal y génitourinario, pueden estar implicados en la brucelosis. El sistema génitourinario se ve afectado en 2% a 20% de los casos con brucelosis. Las formas más comunes de brucelosis son la epidídimo-orquitis, el absceso testicular, y la atrofia. La prueba de aglutinación de suero para detectar la presencia de anticuerpos es una prueba confiable en pacientes con síntomas urogenitales. Se ha hallado que la terapia antibacteriana combinada y a largo plazo son eficaces en la brucelosis. Presentamos dos casos sometidos a orquiectomía debido a una masa testicular antes de que se realizara el diagnóstico de brucelosis.
