A ganglion is a cystic mass with myxoid matrix that occasionally occurs within muscles, tendons, and menisci. A ganglion cyst within the knee is very rare, with few reports to be found. We are reporting eight cases of a ganglion within the knee joint. Our cases include two ganglia in the infrapatellar fat pad which have not been previously reported. Ganglion cysts do not have specific symptoms....

PURPOSE To increase awareness of the presence of ganglion cysts of the anterior cruciate ligament and to consider this diagnosis in any knee that has lost range of motion (ROM) in the absence of osteoarthritis. TYPE OF STUDY Case series. METHODS We present a series of 15 cases recorded over a period of 5 years illustrating the clinical presentation and additional pathology seen at arthrosco...

Ganglion cysts originating from the anterior cruciate ligament (ACL) are uncommon. Often asymptomatic, they infrequently present with non-specific symptoms such as knee pain, stiffness, clicks, locking or restriction of knee extension. However, the patient we report presented with knee flexion restriction. A 37-year-old Chinese gentleman, with no history of knee trauma, presented with left knee...

While clinicians have encountered heme-laden ganglion cysts in the past, to our knowledge the condition has never been described in the literature as a distinct pathological entity, namely, the hemorrhagic ganglion. Because hemorrhage may alter the appearance of an aspirate obtained from a ganglion cyst, and hemosiderin deposition within a ganglion cyst may alter the signal characteristics obse...

Tarlov or perineural cysts are nerve root cysts found most commonly at the sacral spine level arising between covering layers of the perineurium and the endoneurium near the dorsal root ganglion and are usually asymptomatic. Symptomatic sacral perineural cysts are uncommon but sometimes require surgical treatment. A 69-year-old male presented with pain in the buttock. He was diagnosed as having...

Three Chinese patients suffered from severe lumbar spinal stenosis with debilitating symptoms due to a rare condition of ligamentum flavum cysts in the midline of the lumbar spine. This disease is distinct from synovial cyst of the facet joints or ganglion cysts, both intraoperatively and histopathologically. Magnetic Resonance imaging features of the ligamentum flavum cyst are also demonstrate...

Digital mucous cysts are benign ganglion cysts of the digits typically located on the dorsal aspect of the interphalangeal joint and distal phalanx of the digits. Usually the clinical diagnosis is straightforward, though sometimes it may mimic other lesions and diagnosis becomes a challenge. We present a series of three digital mucous cysts with a repeatable dermoscopic pattern consisted of lin...
