INTRODUCTION Intra-articular ganglion cysts of the knee joint are rare occurrences. They are usually encountered as incidental findings in magnetic resonance imaging (MRI), or in arthroscopy. They may originate from both the cruciate ligaments and the menisci, from the popliteus tendon and alar folds, infrapatellar fat pad of Hoffa, and subchondral bone cysts. Those arising from the Hoffa's fat...

BACKGROUND As a rare cause of unilateral leg swelling, extrinsic vein compression caused by intraperitoneal, retroperitoneal, or inguinal lesions has been noted. A rare case of leg swelling as a cause of extrinsic compression of common femoral vein from a ganglion cyst in the groin is presented. CASE PRESENTATION A 38 year old man was referred with a 3 week history of left leg swelling. Follo...

Abstract Ligamentum flavum cyst of the lumbar spine has seldom been described. The mechanism formation these cysts remains unknown, but it is thought to be part degenerative process. Although they are clearly visible on imaging studies, frequently wrongly diagnosed as ganglion or synovial cysts. Bone erosion rarely associated with this pathology. Most common symptom back and radicular pain due ...

Intraosseous ganglia can affect the carpal bones of the hand and must be considered in the differential diagnosis of wrist pain. A 38-year-old female presented with a 14-month history of left wrist pain and a radiolucent cystic lesion was seen computed tomography (CT) scanning. Characteristic radiographic findings of a cyst in association with a fine sclerotic rim was apparent. We report an unu...

Suprascapular nerve compression is a rare cause of shoulder pain. We report the clinical features, radiological findings, arthroscopic management and outcome of three patients with suprascapular nerve compression caused by labral ganglion cyst associated with SLAP lesion. We performed simultaneous suture anchor SLAP repair and cyst decompression with a blunt probe. Upon a two-year follow-up, pa...

We describe a patient with adventitial cystic disease of the popliteal artery with intermittent claudication involving the right calf during exercise. Magnetic resonance imaging (MRI) and computed tomography (CT) revealed a cystic lesion that encircled and compressed the popliteal artery. Resection of the cyst involving a segment of the affected popliteal artery and interposing an autologous ve...

Twenty-two patients with cysts of the lateral meniscus have been treated by operation. A modified operative procedure is described whereby the meniscus is inspected for a concomitant tear. A tear of the meniscus was found in ten patients and these were treated by meniscectomy. The remaining twelve cases were treated by excision of the cyst only. The rehabilitation period was considerably less i...

In a 41-year-old man, right-sided infraspinatus muscle weakness was associated with compression of the suprascapular nerve caused by a spinoglenoid ganglion cyst. The lesion was confirmed using electromyography and MRI. In addition, arthroscopy showed an incomplete discoid labrum. The free inner edge of the labrum was removed as in a meniscectomy of a discoid meniscus in the knee joint. Arthros...

Soft tissue ganglions are commonly encountered cystic lesions around the wrist presumed to arise from myxomatous degeneration of periarticular connective tissue. Lesions with similar pathology in subchondral location close to joints, and often simulating a geode, is the less common entity called intraosseous ganglion. Rarer still is a lesion produced by mucoid degeneration and cyst formation of...
