A 25-year-old woman without personal medical history complained of a unilateral preauricular pain, increased by temporomandibular joint (TMJ) mobilization, that had been evolving for few months. She no traumatic injury. Clinical examination revealed tender right mass, and reduced mouth opening, with maximal opening 33 mm. Oral normal occlusion. Magnetic resonance imaging (MRI) …

Synovial cysts of diarthrodial joints have long been recognized [1]. Clinically, they have most often been found in association with one of the arthritides [2,3]. Though synovial cysts can involve the facet joints of the spine, this fact was little appreciated until very recently [4, 5]. Radiographically, these lesions were extremely difficult to diagnose and were rarely recognized preoperative...

Facet joints are the important articular pillars of spine. Several pathologies can occur in and around facet joint, including extra ossicles, traumatic dislocation, osteoarthritis, synovial cyst, axial spondyloarthritis, rheumatoid arthritis, calcium pyrophosphate deposition disease, septic malignant benign neoplasms. Imaging is mainstay to detect characterize these diseases. In this review, we...

We report a rare case of a "giant Baker's cyst-related rheumatoid arthritis (RA)" with 95 × 26 mm dimensions originating from the semimembranosus tendon. The patient presented with chronic pain and a palpable mass behind his left calf located between the posteriosuperior aspect of the popliteal fossa and the distal third of the calf. In MRI cystic lesion which was located in soft tissue at the ...

Introduction A ganglion cyst can induce symptoms around the knee and should be considered as an intra-articular mass in differential diagnosis. Case Presentation A 22-year-old female presented with a persistent medial knee joint pain in her left knee for 2 years. There was soft tissue swelling on the anteromedial aspect of the infrapatellar region on her left knee. Lachman and McMurray tests ...

Meniscal cysts are rare and often are a result of extrusion of synovial fluid through a tear of the meniscus, resulting in a one-way valve effect of the tear. Arthroscopic partial meniscectomy of the meniscus with intra-articular cyst drainage has become the standard of care. We report a case of an unusually large symptomatic medial meniscal cyst, situated postero-medially and pressing on the p...

Due to a transcription error, the teaching points were mistakenly excluded from this article. Please find the teaching points below: Teaching Points • Ganglion and synovial cysts are frequently associated with osteoarthritis. • A smooth, thin-walled, homogeneous cyst with a stalk connecting to the joint is typical. • Thin septa and internal debris should not be misinterpreted as worrisome findi...

We report the incidence of pseudotumours in a single-surgeon consecutive series of 670 metal-on-metal hip resurfacings performed in the last ten years, with a minimum follow-up of one year. Two cases of pseudotumours have been found and are discussed in detail including metrology and wear analyses of the explanted components. The first was a painless, large synovial cyst in the thigh, secondary...

A cutaneous metaplastic synovial cyst (CMSC) is a cyst lined with metaplastic synovial tissue, which includes the formation of an intracystic villous structure resembling hyperplastic synovial villi. Clinically, the lesion is a tender, subcutaneous nodule that usually occurs at the site of previous surgical trauma and is frequently misdiagnosed as a suture granuloma. The actual cause remains un...
