"Blunt adrenal injury does not affect outcomes in the pediatric population with isolated abdominal injury- a National Trauma Data Bank Review®."

BACKGROUND: The incidence of blunt abdominal injury (BAI) in the adult population has been estimated to be between 0.03% and 4.95%. However, the impact of BAI on the pediatric population remains unknown. METHODS: We conducted a retrospective review of National Trauma Data Bank datasets for the years 2017-2019. We included patients under the age of 18 who experienced blunt trauma and had suffered a blunt abdominal injury with an Abbreviated Injury Scale (AIS) severity score of 2 or higher. RESULTS: Out of the 8064 pediatric patients with isolated abdominal trauma, 134 patients also suffered from BAI. We found no difference in the outcomes of patients with blunt adrenal injury in terms of mortality, length of stay in the intensive care unit (ICU) and hospital, and the number of ventilator days. Within poly-trauma patients BAI was associated with worst patient outcomes. CONCLUSIONS: This study demonstrates that BAI has minimal clinical impact on patient outcomes in isolation. However it is associated with worst outcomes in poly trauma patients suggesting correlation with increased trauma burden. LEVEL OF EVIDENCE: III.

Blunt adrenal gland injury: The impact of extra-abdominal injury.

BACKGROUND: Blunt adrenal gland injuries are considered uncommon. Moreover, the factors associated with the mechanisms of the injury following blunt trauma are unclear. In this study, we determined the factors associated with blunt adrenal gland injury (BAGI). MATERIALS AND METHODS: A total of 315 patients with blunt abdominal trauma were admitted to our institution during a 12-year period. After excluding 26 patients who were under 18 years old and 27 patients who were in cardiopulmonary arrest on arrival, 262 eligible patients were retrospectively reviewed. Patient characteristics, mechanism of injury, intervention, and associated organ injuries were compared between those with and without BAGI. RESULTS: Blunt adrenal gland injury was identified in 38 of 262 patients (14.5%). The right side was the predominant site of injury (68%). There were no differences in vital sign, in-hospital mortality, intervention, and concomitant abdominal organ injuries between those with and without adrenal gland injury. Patients with BAGI had a higher frequency of fall and motorcycle collision as mechanisms of injury. In addition, patients with BAGI had a higher injury severity score and a higher frequency of concomitant severe head, chest, and pelvic injuries. CONCLUSION: The results of the present study suggest that the deceleration injury leading to concomitant head, chest, or pelvic injuries with blunt abdominal trauma may be associated with the mechanism of BAGI. LEVEL OF EVIDENCE: Prognostic study, level IV.

Hemorrhagic adrenal myelolipoma after trauma to left adrenal gland: A case report.

Myelolipomas are rare benign tumors comprised of mature adipose tissue and hematopoietic elements. Adrenal myelolipomas associated with traumatic adrenal injury are relatively rare and less common on the left due to the limited size and well-protected position of the gland. A 59-year-old female admitted to the emergency department with intermittent left flank pain radiating to the left abdomen after falling from the bed six hours earlier. Her vital signs were stable, and she had tenderness over the left flank area and left abdomen. Her initial hemoglobin level was 12.9 g/dL. Bedside focused assessment with sonography for trauma revealed unclear left kidney margins. Contrast abdominal computed tomography (CT) revealed a space-occupying mass, 11.6×10.4×8.8 cm in dimension, in the left suprarenal region with active bleeding in the lower pole. Angiography did not reveal any active contrast medium extravasation. The CT-guided biopsy, was well performed concomitantly with angiography. Pathological assessment of the biopsy specimen revealed the presence of mostly adipose tissue with few erythrocytes and leukocytes. She was diagnosed with adrenal myelolipoma and admitted to the urology ward for left adrenalectomy with tumor resection. Traumatic adrenal injury, an unusual presentation of adrenal myelolipoma incidentally found in less than 5% of all abdominal blunt injuries, should be considered in cases of bleeding with trauma to the flank for prompt treatment.

Diagnostic utility of cytology smears and cell block in adrenal lesions.

BACKGROUND: Cytology of the adrenal gland is a less performed technique even in tertiary care centres; yet cytological evaluation is an important diagnostic tool for assessment of adrenal lesions. Our objective was to evaluate the diagnostic utility of FNAC smears and cellblock with immunohistochemistry (IHC) in lesions of the adrenal. MATERIAL AND METHODS: We had a total of 50 cases over a period of 2 years where both FNAC smears and cellblocks were taken. The smears and cellblocks were examined for adequacy. They were subsequently categorised into four groups: unsatisfactory, benign, suspicious of malignancy and malignant. The diagnostic accuracy of FNAC smears and cellblock with IHC were evaluated and compared, taking histopathology, wherever available, as the gold standard, RESULT: We had 50 cases with age ranging from 6 to 53 years with a median of 7.5 years. Of these, 54% were cytologically malignant and neuroblastoma was the commonest lesion. Histopathology was available in 23 cases only, where the diagnostic accuracy was evaluated. The sensitivity and specificity of FNAC smear was 100% and 85.71%, respectively whereas the sensitivity and specificity of cellblock with IHC was 100% and 92.86%, respectively. CONCLUSION: Cellblock together with IHC provides a higher degree of specificity, reduces the unsatisfactory rate and improves the diagnostic accuracy in lesions of the adrenal gland. Immunohistochemistry is an important adjunctive tool.

Postmortem Computed Tomography and Magnetic Resonance Imaging of an Abdominal Gunshot Wound.

The use of postmortem computed tomography (CT) has been described in many articles concerning gunshot injuries. Postmortem magnetic resonance imaging (MRI) for better assessment of soft tissue injuries has also been mentioned in the literature, albeit much less often. The use of postmortem MRI for abdominal gunshot wounds has not been previously presented in the literature. The present case report describes the findings of an abdominal gunshot wound detected by postmortem CT and MRI, followed by an autopsy. The main imaging findings on CT were a hyperdense ring at the entrance wound, which indicated the muzzle imprint mark, a hyperdense region beneath the skin, which was suggestive of combustion residue, gas cavities surrounding the bullet path, which might be related to the temporary cavity, and a fracture of the 13th rib on the left. Magnetic resonance imaging provided a clear depiction of defects in the muscle tissue and peritoneal fat, as well as an injury to the left kidney and a large volume of blood in the abdominal cavity. Computed tomography combined with MRI provided a descriptive presentation of the intracorporeal trajectory noninvasively. Autopsy confirmed the radiologic findings but additionally revealed further relevant findings, which were not detected radiologically, such as a duodenal perforation. Autopsy also detected subendocardial hemorrhages and shock kidney, which were consistent with severe blood loss.The imaging findings and their interpretations are discussed in this case report, as well as the role of CT and MRI in the assessment of abdominal gunshot wounds compared with autopsy.

Adrenal gland injury due to gunshot.

Adrenal gland trauma is a rare phenomenon, due to the small size and retroperitoneal location of the organ. The majority of adrenal gland trauma is due to blunt force injury and is only rarely encountered due to the penetrating mechanisms. A 20-year-old male sustained a gunshot wound to the left abdomen. Upon exploration, he was found to have a through and through injury to the left adrenal gland, among other injuries. Injury to the adrenal gland due to penetrating trauma is exceptionally rare. The principles of management are to control bleeding from the gland with debridement and hemostasis rather than attempt to resect the entire organ. The management of a penetrating injury to the adrenal gland is straightforward and should not be a contributor to a patient's morbidity or mortality.

Bilateral adrenal haemorrhage after a high energetic trauma: a case report and review of current literature.

Most adrenal injuries are asymptomatic. In traumatic events, adrenal haemorrhage is very likely to be accompanied by injuries to other organs. Isolated adrenal injury after trauma is very rare and mostly unilateral. We report a case of a 44-year-old male who suffered a major traffic accident with multiple trauma, including a bilateral adrenal haemorrhage. This caused a primary adrenal insufficiency, as proven with a cortisol stimulation test with synthetic corticotrophin. Bilateral adrenal haemorrhage is a very rare but potentially fatal disorder and should not be missed. This case illustrates that early diagnosis and prompt treatment with hydrocortisone may contribute to a beneficial outcome.

Development of multiple adrenal myelolipomas after trauma-induced adrenal haemorrhage.

Adrenal myelolipomas represent a benign neoplasm with known associations with many chronic diseases, 21-hydroxylase deficiency and cancer. However, the aetiology of adrenal myelolipomas remains unknown. Here, we present a case of a patient with image-proven bilateral adrenal haemorrhages caused by trauma with the subsequent development of bilateral adrenal myelolipomas several years later. Resection and pathological analysis of left adrenal gland confirmed the presence of multiple adrenal myelolipomas. Our case strongly suggests that trauma was the inciting event that led to the formation of these lesions.

[Traumatic Adrenal Injury : A Single-Institution Experience].

Traumatic adrenal injury is quite rare. From January 2008 to March 2018, out of 287 patients with genitourinary trauma, 23 patients (8%) were diagnosed with traumatic adrenal injury at Kobe City Medical Center General Hospital. We retrospectively reviewed the medical records and assessed the traumatic category, image findings and outcome. All 23 patients were bluntly injured. The causes of traumatic adrenal injury were motor vehicle accident (11 patients : 48%) and falls (9 patients : 39%). The majority of injuries occurred on the right side (18 patients : 78%). Associated injuries occurred in all 23 patients, most frequently in the liver (57%) and ribs (57%). Extravasation of contrast materials was identified on computed tomography (CT) in 4 patients (17%). Although 22 patients (96%) were conservatively managed, only 1 patient was treated by transcatherter arterial embolization because of hypotension. One patient died of intraabdominal bleeding. To our knowledge, the present study is the largest on traumatic adrenal injury in Japan.

Blunt Adrenal Injury: Results of a State Trauma Registry Review.

In the past, injuries to the adrenal glands due to blunt trauma were considered rare, and were reported to be associated with high Injury Severity Scores (ISSs) and high mortality. Recent reports have reported a much high incidence associated with lower ISS and lower mortality. The purpose of this study was to assess the incidence of adrenal gland injuries due to blunt trauma in a large state trauma registry and determine whether these injuries are associated with a higher ISS and increased risk for mortality. A retrospective review was performed on the New York State Trauma Registry comparing blunt injured adults with adrenal injuries to those who did not. Concurrent organ injuries, ISS, and inhospital mortality were compared. Three hundred thirty-nine patients with adrenal gland injuries were identified. Concurrent liver and kidney injuries were more prevalent in the adrenal injured group, and concurrent injuries to the small and large intestine and spleen were more prevalent in the nonadrenal injured group. There was no difference in ISS or mortality between the adrenal injured and nonadrenal injured populations. The results of this study are consistent with recent smaller studies which identified incidence rates which were higher than previously reported and that ISS and mortality risk were unchanged by the presence of blunt adrenal gland injuries. Adrenal gland injuries due to blunt trauma are not uncommon, with an incidence rate of 0.61 per cent. Adrenal gland injuries are not associated with higher ISS or an increased risk of mortality.

Management of blunt adrenal gland injury in a community-based hospital.

INTRODUCTION: Injury of the adrenal gland in blunt trauma is rare. The routine usage of the whole body computed tomography (CT) scan helps in early diagnosis. We aimed to study the incidence, mechanism of injury, management, and outcome of adrenal injury in blunt trauma patients treated in a community-based hospital. METHODS: CT scan of the abdomen of all blunt trauma patients who were admitted to our institution between October 2010 and March 2018 were retrospectively reviewed. The files of all the patients with CT scan-detected adrenal injuries were retrieved. Studied variables included demography, mechanism of injury, associated injuries, GCS, ISS, Intensive Care Unit admission, hospital stay, and outcome. RESULTS: 4991 blunt trauma patients were admitted to the hospital. CT scan of the abdomen was performed for 2359 (47%) patients. Blunt adrenal injuries were diagnosed in eleven male patients (0.22%). The main mechanism of injury was motor vehicle collisions in eight (72.7%) patients. Nine (81.8%) patients had right adrenal gland injury. The mean (range) ISS was 22 (6-50). All patients had intra-adrenal hematoma and periadrenal fat stranding. None of our patients had acute adrenal insufficiency. One patient died (overall mortality 9.1%). CONCLUSIONS: The incidence of blunt adrenal injury, although rare, is similar in a community-based hospital to those reported from trauma I centers. It is associated with severe and multiple organ injuries. Blunt adrenal injuries are usually self-limiting.

Lesões de adrenais em 300 cães / Adrenal lesions in 300 dogs

Foram estudadas as adrenais de 300 cães submetidos à necropsia no Laboratório de Patologia Veterinária da Universidade Federal de Santa Maria, no período de março de 2012 a junho de 2013. Os tecidos coletados foram fixados em formol 10% e encaminhados ao processamento his­tológico de rotina para confecção e análise de lâminas histológicas. Posteriormente, foram revisados os protocolos de necropsia e dados epidemiológicos referentes aos cães que tiveram as adrenais coletadas foram anotados. Dos 300 cães analisados, 82% tinham uma ou mais alterações nas adrenais, que foram classificadas de acordo com a patogênese e a prevalência. Lesões hiperplásicas foram as mais prevalentes, com 91,5% das ocorrências, seguido de lesões degenerativas (26,%), circulatórias (20,3%), neoplásicas (15%), inflamatórias (4,1%) e outras lesões (14,2%). Macroscopicamente, as hiperplasias caracterizavam-se por variável quantidade de nódulos brancacentos, de até 1,5cm de diâmetro. Em 72,9% dos casos de hiperplasia, os nódulos eram constituídos de células da camada glomerulosa. A maioria dos animais que apresentou lesões hiperplásicas era constituída de fêmeas (60,4%), idosos (46,9%) e cães com raça definida (55,6%). A degeneração gordurosa foi a lesão degenerativa mais prevalente (54,7%) e era caracterizada por células da zona fasciculada e da zona reticular com grandes vacúolos citoplasmáticos. Entre as alterações neoplásicas, tumores primários foram mais prevalentes (75,7%), com predomínio de adenomas (57,1%), seguido de feocromocitomas (25%) e carcinomas corticais (17,9%). Os tumores metastáticos perfizeram 24,3% dos casos de alterações neoplásicas. As adrenais foram sítio de metástase de carcinoma mamário, osteossarcoma, melanoma, linfoma, colangiocarcinoma, sarcoma histiocítico e adenocarcinoma pulmonar. No item "outras lesões", adrenal de estresse foi a alteração mais prevalente (37,1%). Essa alteração era caracterizada histologicamente por córtex de aspecto variegado, com áreas de fina vacuolização citoplasmática das células da camada fasciculada, intercaladas por grupos de células hipereosinofílicas. Este estudo possibilitou concluir que lesões nas adrenais de cães são extremamente frequentes, de modo que a avaliação cuidadosa desse órgão se faz necessária na rotina de diagnóstico em patologia.(AU)

The adrenal glands of 300 dogs, underwent to necropsy in the Laboratório de Patologia Veterinária at the Universidade Federal de Santa Maria (LPV/UFSM), were studied from March 2012 to June 2013. The collected tissues were fixed in 10% buffered formalin and sent to the routine histological processing in order to preparation and analysis of histological slides. Subsequently, it was reviewed the necropsy reports and the epidemiological data of the dogs which had the adrenal glands collected. Out of the 300 dogs examined, 82% had one or more adrenal lesions that were classified according to the pathogenesis and prevalence. The hyperplastic lesions were the most prevalent, comprising 91.5% of the cases, followed by degenerative (26%), circulatory (20.3%), neoplastic (15%), inflammatory (4.1%) and other lesions (14.2%). Grossly, hyperplasia was characterized by a variable amount of whitish nodules, ranging from 0.2-1.5 cm of diameter. In 72.9% of the hyperplasia cases, the nodules were composed by cells of the glomerulosa zone. Most of the animals that showed hyperplastic lesions consisted of females (60.4%), elderly (46.9%) and purebred dogs (55.6%). Fatty degeneration was the most prevalent degenerative lesions (54.7%), characterized by cells of the fasciculata and reticularis zones with large cytoplasmic vacuoles. Among the neoplastic changes, primary tumors were the most prevalent (75.7%), with predominance of adenomas (57.1%), followed by pheochromocytomas (25%) and cortical carcinomas (17.9%). Metastatic tumors corresponded to 24.3% of all cases of neoplastic changes. The adrenal glands were the site of metastasis of mammary gland carcinoma, osteosarcoma, melanoma, lymphoma, cholangiocarcinoma, histiocytic sarcoma and lung adenocarcinoma. Under "other lesions", adrenal of stress was the most prevalent change (37.1%). It was characterized histologically by a cortex with irregular appearance, with areas of mild cell vacuolation in the fasciculata zone, interspersed with hypereosinophilic cell groups. This study allowed the conclusion that the lesions in adrenal glands of dogs are extremely common, highlighting the importance of a careful evaluation of this organ in the routine of pathological diagnostic.(AU)

Pediatric adrenal trauma: evaluation and follow-up with contrast-enhanced ultrasound (CEUS).

Adrenal trauma is rarely encountered in the pediatric population, often as a component of multi-organ injury and often presenting with hematoma formation. Contrast-enhanced computed tomography (CECT) is the established imaging modality both for initial evaluation and follow-up of patients with blunt abdominal trauma. In children, radiation exposure should be minimized and alternative imaging strategies are needed. Contrast-enhanced ultrasound (CEUS) has recently been successfully used for evaluation of patients with hepatic, renal and splenic injury. We present three cases of children with post-traumatic adrenal hematomas, which were initially diagnosed with CECT and subsequently followed up with CEUS, suggesting that CEUS may be considered for follow-up of adrenal injuries in children. CEUS improves the diagnostic capabilities by increasing tissue contrast and spatial resolution, readily differentiating viable from necrotic tissue in comparison to conventional ultrasound without the risk of iodine contrast agents and ionizing radiation of repeated CECT examinations.

Isolated unilateral adrenal gland hemorrhage following motor vehicle collision: a case report and review of the literature.

BACKGROUND: Adrenal gland trauma is a rare condition that typically stems from blunt force trauma, and is associated with multiple organ injuries. Alternatively, isolated adrenal gland trauma is extremely rare, accounting for only 1.5 to 4% of all adrenal trauma cases. While isolated adrenal trauma is a mostly self-limiting condition, it is potentially life-threatening, representing a significant cause of bleeding, and/or hypotension due to adrenal insufficiency and adrenal crisis. Due to its rare occurrence, there are no reported guidelines for monitoring and observing isolated adrenal trauma. CASE PRESENTATION: Here we report on an isolated adrenal hemorrhage from a blunt trauma without associated injuries. A 53-year-old white man presented with abdominal pain after a high-speed motor vehicle accident. An initial evaluation revealed minimal abdominal pain and negative focused assessment with sonography for trauma examination; computed tomography imaging revealed a significant fluid collection consistent with adrenal hemorrhage. He was observed in our intensive care unit for 24 hours, and had stable hemoglobin and vital signs, after which he was discharged. At 1-month follow-up, he reported persistent intermittent abdominal pain, which was completely resolved by the 4-month follow-up. CONCLUSIONS: This case report demonstrates isolated adrenal gland injury resulting from significant blunt trauma to the abdomen. There are no current guidelines for monitoring isolated adrenal hemorrhage. Recognizing possible adrenal injury in blunt trauma cases is important due to potentially severe adrenal hemorrhage; therefore, we recommend follow-up with serial abdominal computed tomography until the resolution of hemorrhage and symptoms.
