RESUMEN
An interosseous ganglion cyst is a very rare entity, found mostly in skeletally mature patients, particularly in long bones such as the tibia and femur. However, we are the first to report here an unusual case of interosseous ganglion cyst of the upper ribs in a young female patient, which she had an unpredicted presentation of cough and hemoptysis and a large painful lump over the anterior left upper chest. The radiological and pathological workup confirmed the presence of a benign interosseous ganglion cyst arising from the left first rib, invading the second rib and the apex of the left lung. The patient has been treated successfully by surgical resection of this rib cyst. However, we could not find any reported cases in the current literature of an interosseous ganglion cyst pathology arising in the ribs with a similar presentation of cough and hemoptysis.
RESUMEN
Ganglion cysts arising from the plantar aspect are rare, and the most common location of the foot and ankle is the dorsal aspect of the foot. We present a case of a 49-year-old man with pain in the right foot. Plain radiographs showed thinning of the cortical bone in the right second and third metatarsals, and MRI showed cystic lesions between the second and third metatarsals, resulting in stress reactions and fractures. The fracture gradually remodeled and completely healed following resection of the ganglion cysts. If plain radiographs show atypical changes in the metatarsal bone morphology, a ganglion cyst, as in this case, should be suspected, and MRI should be considered.
RESUMEN
Introduction and importance: Hoffa's fat pad (HFP), also known as infrapatellar fat pad, is one of the three fat pads in the knee. Ganglion cyst (GC) rarely arises from HFP which presents knee pain and swelling. Case presentation: A 43-year-old female presented with left knee pain for 1 year and swelling in her left knee for 6 months. Clinical examination revealed a palpable swelling of size around 3 cm×2 cm over the anteromedial aspect of the left knee. The size of the swelling increased on extension and decreased on flexion of the knee. A musculoskeletal ultrasound of the left knee revealed a lobulated anechoic lesion of size â¼2.3 cm×2 cm in HFP. Open excision of cystic mass through medial parapatellar approach was done, and histopathological examination showed findings consistent with GC. At 6 months follow-up, there was no residual swelling and no recurrence. She was symptom-free on her recent evaluation after 1 year of operation. Clinical discussion: GCs arising from HFP are much rarer among the cysts around the knee. Diagnosis is primarily done by magnetic resonance imaging. However, the use of ultrasonography has grown in the diagnosis of the GC. Among different modalities of treatment, open excision is the most recommended to prevent recurrence and incomplete resection. Conclusions: This case illustrates the importance of ultrasonography in the early diagnosis of HFP GC and reserving more costly and time-consuming imaging modality magnetic resonance imaging for localizing the extent of the cyst. We recommend an open resection to avoid recurrence and incomplete resection of the cyst.
RESUMEN
OBJECTIVES: To assess radiopalmar ganglion cysts' (RPG) prevalence, morphology, and clinical significance in consecutive patients. MATERIALS AND METHODS: In this retrospective single-center study, two radiologists assessed the presence of RPG and morphologic features on wrist MRI. Radiopalmar complaints and scapholunate ligament (SLL) tears were evaluated. RESULTS: A total of 1053 wrists in 909 patients (mean age 43.4 ± 15.5 years, 602 females) were evaluated. All 308 RPG (Group 1; 308 patients, 29.2%) originated from the palmar capsule; 49 were unilocular, 95 oligolocular, and 164 multilocular; 745 wrists had no RPG (Group 2; 601 patients). One hundred and twenty-six RPG showed internal debris. The mean diameter was 8.5 ± 5.6 mm (cranio-caudal) (1.0-32.9 mm), 8.0 ± 4.1 mm (medio-lateral) (1.0-31.9 mm), and 3.7 ± 2.3 mm (dorso-palmar) (0.4-16.0 mm). 168 RPG showed direct contact with the radial vascular bundle, 24 with the flexor carpi radialis tendon, and 123 with the flexor pollicis longus tendon. In Group 1, significantly more patients showed partial (82/308) [group 2: 45/745, p < 0.001] or complete SLL tears (22/308) [group 2: 20/745, p < 0.001]. Of the patients with RPG, 15.3% presented with radiopalmar complaints. Only the dorso-palmar RPG diameter was positively correlated with radiopalmar complaints (for readers 1 and 2: rs = 0.66/0.61, p < 0.001, respectively), and the best dorso-palmar diameter cut-off value for the probability of having radiopalmar complaints was defined at 3 mm (area under the curve (AUC) 0.74). Other morphologic features were not eligible to discriminate symptomatic patients (AUC range 0.53-0.61). CONCLUSION: This study found RPG in 29% of patients, most of them asymptomatic. However, a dorso-palmar cyst diameter > 3 mm may be clinically significant. CLINICAL RELEVANCE STATEMENT: Radiopalmar ganglion cysts, observed in 29% of wrist MR examinations, are mostly asymptomatic, but those with a larger dorso-palmar diameter may be associated with radiopalmar complaints. KEY POINTS: Radiopalmar ganglion cysts are found in 29% of patients undergoing wrist MRI. Most patients with evidence of radiopalmar ganglion cysts do not show radiopalmar symptoms (85%). A dorso-palmar cyst diameter > 3 mm may be associated with radiopalmar complaints.
RESUMEN
Wrist ganglion cysts are the most common benign soft tissue swelling in the hand and wrist. They may arise from flexor and extensor tendon sheaths, interphalangeal joints, wrist joints, and even the neural tissues around the hand and wrist. Some volar wrist ganglion cysts arise from the radiocarpal joint and scaphotrapezial joint. It is uncommonly encountered as an incidental finding during the fixation of a distal radius fracture. In our case, a volar wrist hemorrhagic ganglion cyst was incidentally found during the fixation of the fracture. Prior to the injury, the patient had no complaints of swelling over her right wrist. The cyst was removed using microscopic magnification.
RESUMEN
BACKGROUND: The articular origin of intraneural cysts has been previously described and well supported. Intraneural ganglion cysts most commonly occur in adults and in the common peroneal nerve arising from the anterior aspect of the superior tibiofibular joint (STFJ). OBSERVATIONS: The authors report a pediatric patient who developed a tibial intraneural cyst arising from the posterior aspect of the STFJ within months after surgical treatment of a peroneal intraneural cyst from the anterior aspect of the same joint. Surgery consisted of disconnecting the articular branch of the peroneal nerve and decompression of the cyst. Three-month postoperative magnetic resonance imaging showed resolution of the peroneal intraneural cyst and anterior compartment denervation but demonstrated a clinically occult small tibial intraneural ganglion cyst arising from the STFJ with popliteus muscle atrophy. LESSONS: This case underscores the importance of addressing the underlying etiology (articular synovitis) or the communication pathways (articular branches) whenever feasible to mitigate intraneural cyst recurrence. Furthermore, this report reinforces the validity of the articular theory. https://thejns.org/doi/10.3171/CASE24277.
RESUMEN
Background: A synovial cyst is a herniation of synovial tissue through a joint capsule, often mistaken for a ganglion cyst. The key distinctions are that synovial cysts have a synovial cell lining, while a ganglion cyst is delineated by dense fibrous connective tissue. Typically found near joints, synovial cysts are associated with conditions like osteoarthritis, prevalent in females aged 20 to 50. We present a rare case of a synovial cyst in the extensor digitorum superficialis of the right hand. Case summary: A 53-year-old Hispanic female visited our hand clinic due to a 3-year history of pain on the back of her right hand. At exploration, a 3 × 3 cm soft tumor was identified. Surgery revealed a clear-yellowish mass within the extensor digitorum superficialis tendon. Following the surgery, synovial cyst was confirmed by pathology and the patient was discharged without complications. Conclusion: This case highlights the rare presentation of an intratendinous synovial cyst and emphasizes the importance of a comprehensive understanding of synovial cysts in the differential diagnosis of hand tumors.
RESUMEN
Ganglion cysts represent a small group of lesions that can arise from almost any joint in the body. Demonstrating a predilection for the joints in the hand and wrist, ganglion cysts in the glenohumeral joint are extremely rare. Due to the vivid array of masses that can be found in the axillary fossa, forming a free-from-error work-up to the correct diagnosis can be quite confounding. In this paper, we present a case of a paralabral cyst of the shoulder joint, located in the axilla. With there being only eight other such cases published in clinical literature, we believe this case report to be of unique importance in gaining further insight into the genesis and treatment of this pathology.
RESUMEN
INTRODUCTION AND SIGNIFICANCE: Ganglion cysts in the thigh area are uncommon, typically occurring in the wrist and ankle. These cysts are usually painless but may compress nearby structures, causing discomfort. Ultrasound is a valuable tool to differentiate ganglion cysts from hematomas and lipomas. It also helps identify the fluid-filled cyst walls. Treatment typically involves surgical removal, with complete resection being the goal. CASE PRESENTATION: We present a case of a woman who experienced a gradual increase in size of a lump in her groin area. The lump was later diagnosed and completely removed. Histological analysis revealed the presence of a ganglion cyst. CLINICAL DISCUSSION: Clinical examination is crucial for diagnosing superficial ganglion cysts. It allows us to assess their separation from the skin and connection to deeper structures. It's important to consider ganglion cysts as part of the differential diagnosis for cystic lesions in the groin area during routine medical practice. This can help avoid unnecessary and expensive tests like MRI scans in some cases. CONCLUSION: Developing a thorough differential diagnosis for uncommon lesions in specific anatomical areas is essential in clinical practice. This aids in choosing appropriate diagnostic methods and surgical intervention, if necessary, to prevent recurrence of the condition.
RESUMEN
A ganglion cyst is a benign mass consisting of high-viscosity mucinous fluid. It can originate from the sheath of a tendon, peripheral nerve, or joint capsule. Compressive neuropathy caused by a ganglion cyst is rarely reported, with the majority of documented cases involving peroneal nerve palsy. To date, cases demonstrating both peroneal and tibial nerve palsies resulting from a ganglion cyst forming on a branch of the sciatic nerve have not been reported. In this paper, we present the case of a 74-year-old man visiting an outpatient clinic complaining of left-sided foot drop and sensory loss in the lower extremity, a lack of strength in his left leg, and a decrease in sensation in the leg for the past month without any history of trauma. Ankle dorsiflexion and great toe extension strength on the left side were Grade I. Ankle plantar flexion and great toe flexion were Grade II. We suspected peroneal and tibial nerve palsy and performed a screening ultrasound, which is inexpensive and rapid. In the operative field, several cysts were discovered, originating at the site where the sciatic nerve splits into peroneal and tibial nerves. After successful surgical decompression and a series of rehabilitation procedures, the patient's neurological symptoms improved. There was no recurrence.

The main objective was to describe the different types and characteristics of lumbar spine extradural cysts and their optimal treatment options with a focus on endoscopic technique. We searched Pubmed, EMBASE, Medline, and Google Scholar for articles published between 1967 and 2020 using the keywords "Spinal Cyst," "Extradural Cyst," and "Lumbar Cyst." The various anatomical and histological types of the extradural cysts with their presentations, etiologies, imaging, and optimal treatment with a focus on endoscopic techniques were reviewed from the articles. Lumbar spinal cysts are relatively rare pathologies that might cause radicular symptoms similar to lumbar disc herniation. Spinal extradural cysts are classified either histologically based on the cyst lining tissues (synovial cysts or non-synovial, ganglion cysts) or anatomically based on the structure of origin (epidural cysts, ligamentum flavum cysts, discal cysts, post-discectomy pseudocysts, posterior longitudinal ligament cysts, facet cysts). Surgical excision is the recommended treatment of symptomatic cysts with endoscopic techniques being a viable option. Extradural lumbar cysts can be identified based on their histological structure or depending on their structure of origin. Regardless of their classification, they could all give similar clinical findings, and the optimal treatment would be surgical excision with endoscopic technique being a viable option with a satisfactory outcome.
RESUMEN
In total, 38 patients with cystic dorsal wrist tumours managed with surgical excision were prospectively followed up for 2 years. Tissue was examined histologically after primary surgery and at recurrence. Two distinct tissue types were found: ganglion cyst and synovial cyst.
RESUMEN
BACKGROUND: Sclerotherapy has shown superior efficacy among the nonsurgical options for managing digital mucous cysts (DMC). Notably, previous research has indicated that bleomycin offers a more favorable side-effect profile and similar efficacy to conventional sclerosing agents. OBJECTIVE: This study aimed to assess the efficacy and safety of bleomycin intralesional injection (ILI) for treating DMC through a comparative analysis of corticosteroid ILI and surgical excision. METHODS: We retrospectively reviewed electronic medical records and clinical photographs. Telephone interviews were conducted to further investigate long-term treatment efficacy, safety, and overall treatment satisfaction. RESULTS: Ten patients underwent surgical excision, and 13 and 15 patients received bleomycin and corticosteroid ILI, respectively. Both surgical excision and bleomycin ILI demonstrated superior treatment efficacy compared to corticosteroid ILI. No statistically significant difference in the treatment effectiveness between surgical excision and bleomycin ILI was observed. No significant adverse effects were observed. In the survey, the level of satisfaction was the highest for bleomycin ILI, followed by surgical excision and corticosteroid ILI. CONCLUSION: This study revealed that bleomycin ILI exhibits a treatment efficacy higher than that of corticosteroid ILI and slightly lower than that of surgical excision, without any side effects. Therefore, bleomycin ILI is a safe and effective therapeutic option for the treatment of DMC.
RESUMEN
Benign cartilaginous lesions called enchondromas usually appear in the long bones of the limbs. This case report, however, draws attention to an uncommon and unusual appearance of enchondroma near the medial end of clavicle. Because of the unusual location, the diagnostic process was very complex, which presented a challengefor the physicians. We provide the clinical, radiological and histological results that finally allowed for an accurate diagnosis. This example highlights the need of taking into account atypical location for benign lesions and highlights the necessity of a thorough diagnostic approach in unexpected clinical settings. Since the occurrence of clavicular enchondromas is a rare entity and can at times mislead the clinician, healthcare providers must be vigilant enough to guarantee a prompt and accurate diagnosis for timely intervention.
RESUMEN
Acromioclavicular ganglion cysts are uncommon, with only a limited number of cases reported in the medical literature. This case report presents a unique instance of an acromioclavicular ganglion cyst in an 81-year-old male patient, outlining the clinical presentation, diagnostic approach, and successful surgical management. The purpose of this report is to contribute to the existing body of knowledge on this rare condition and highlight the importance of accurate diagnosis and appropriate intervention.
RESUMEN
Ganglion cysts are typically periarticular soft tissue lesions commonly found in the wrist and forearm, with spinal involvement being rare. We present a clinical case of a 54-year-old female with a ganglion cyst at the L3-L4 level, causing radiculopathy symptoms. Despite initial difficulty in diagnosis due to MRI findings, surgical resection confirmed the extradural mass as a ganglion cyst. Postoperative recovery was uneventful, with immediate relief of radiculopathy symptoms. Challenges included distinguishing between synovial and ganglion cysts and accurately locating the cyst intraoperatively. This case highlights the importance of considering ganglion cysts in the differential diagnosis of spinal lesions and underscores the efficacy of surgical management for symptomatic relief.
RESUMEN
We briefly describe the case of a 4-year-old girl, referred for imaging of a small, firm, round, skin-colored, subcutaneous nodule that suddenly appeared at her right sternoclavicular junction. A plain radiograph was non-contributory, but ultrasonography revealed a small cystic structure, leading to the diagnosis of a sternoclavicular ganglion cyst. Sternoclavicular ganglion cysts are a rare diagnosis, with only seven reported pediatric cases. A watchful waiting approach can be adopted so long as they remain asymptomatic.

Introduction: Intraosseous ganglion cysts are an uncommon variant found in the subchondral bone. We report here the development of an intraosseous ganglion cyst of the proximal tibia in the setting of a prior left total knee arthroplasty (TKA) with an all-polyethylene tibial component. Case Report: The cyst was diagnosed on routine follow-up radiographs approximately 4 years status post-TKA. Although initially asymptomatic, 1 year later the patient presented with progressive knee pain and ambulation limitations, so revision TKA was indicated. Computed tomography confirmed an osteolytic lesion suggestive of a penetrating ganglion. Given the absence of malrotation or malalignment of the well-fixed femoral component, the decision was made to proceed with tibial revision to stemmed component cemented through a porous tantalum cone. Postoperatively, the patient had complete resolution of pain and instability with 0-120° of stable range of motion, which has persisted to the latest follow-up at over 6 months post-operative, with radiographic resolution of the cyst. Conclusion: This case demonstrates a ganglion cyst surrounding total knee implants as a possible source of persistent pain following TKA. To our knowledge, this is the first report of such a case. This case demonstrates that refractory painful knee implants secondary to tibial ganglion cysts can be treated successfully with revision arthroplasty.
RESUMEN
BACKGROUND: Spontaneous resolution of a spinoglenoid notch ganglion cyst (SGC) without surgical treatment has been rarely reported; however, we have encountered this phenomenon occasionally. Therefore, we aimed to describe a case series of consecutive patients with SGC in whom it spontaneously resolved without surgical treatment. METHODS: We retrospectively reviewed 12 patients with magnetic resonance imaging (MRI)-confirmed SGC in whom it resolved without surgical treatment between January 2011 and March 2023. We included patients without abnormally increased signal intensity or muscle atrophy due to denervation from suprascapular neuropathy on MRI. Resolution of the SGC was confirmed via MRI or ultrasound at the follow-up visit, and suprascapular neuropathy was assessed using electromyography and nerve conduction studies when needed. For functional assessments, the visual analog scale for pain and active range of motion of the shoulder were used to compare pre and postresolution follow-ups. RESULTS: Eleven men and 1 woman with a median age of 54.0 years (interquartile range [IQR] 37.0-65.3) were included in this study. The SGCs resolved spontaneously at a median of 13.2 months with an IQR of 8.2-23.0 after initial evaluation using MRI. The SGCs were multiloculated cysts with superior labrum anterior and posterior II-IX lesions, with a median diameter of 2.5 cm (IQR 2.0-2.8). The median visual analog scale for pain (pre-resolution 5.0 [IQR 4.0-7.0] vs postresolution 1.0 [IQR 0.0-1.0], P = .002) and internal rotation at the back (preresolution 8.0 [IQR 7.0-10.3] vs postresolution 7.5 [IQR 7.0-8.0], P = .034) were significantly improved after the resolution. CONCLUSIONS: Surgical treatment may not be necessary in all cases of SGC. Nonsurgical treatment may be a viable option in the absence of suprascapular nerve involvement or superior labrum anterior and posterior-related physical findings.
