“…In addition, GCTTS is more uniform and has a mixed cell population that can help to distinguish it from fibromas. [14] The primary clinical diagnosis in our patient was meniscal injury or ACL tear. After radiological evaluation with MRI, we suspected GCTTS or fibroma but after arthroscopic excision with arthroscopy and histopathological examination, a final diagnosis of localized tenosynovial GCTTS was established.…”

“…[1,13] Pigmented villonodular synovitis is histologically identical with GCTTS but it most commonly involves the whole synovium in larger joints and pronounced hemosiderin, which produces a characteristic signal on MRI. [14] Giant cell tumor of the tendon sheath and ganglion cysts can be distinguished by ultrasound; GCTTS is solid, nodular, and has internal vascularity while a ganglion cyst has a cystic component with well-defined borders and no internal vascularity. [4,15] Fibromas and GCTTS have distinct features on MRI, including differences in lesion morphology and intensity patterns.…”

A rare localized giant cell tumor of the tendon sheath originating from the ligamentum mucosum: A case report

A 27-year-old male patient with no significant past medical history was admitted to the orthopedic emergency department of our hospital with a painful locked right knee. There was no history of either trauma or any unusual sports injury. He reported suffering from mild pain, which was worse with activity, and a decreased range of motion for two years but denied any swelling or locking of the knee during this period. Physical examination revealed massive swelling and tenderness along the joint line and increased pain with active and passive motion of the knee. Specific knee joint tests could not be performed due to excessive pain. There were no signs of inflammation (erythrocyte sedimentation rate, C-reactive protein, and total blood count tests were normal). Plain radiography of the knee joint was also

“…5,6 Although diffuse-type TGCT may occur in the joints and extend into the tendon sheaths, it generally exhibits a lobulated or casting mold pattern with a hypointense ring on proton density-weighted imaging. 7 In patients with diffuse-type TGCT, it is uncommon to see a hypointense signal inside the tendon. Although TGCT was not definitively diagnosed and was finally excluded as a differential diagnosis, we used its treatment for reference.…”

Infiltration of synovitis into the flexor tendon: a case report

2020

View full text Add to dashboard Cite

Synovitis is a type of aseptic inflammation that occurs within joints or surrounding tendons. No previous reports have described a hypertrophic synovium eroding the tendon sheath and manifesting as synovitis within the flexor tendon. We herein report a case involving a 10-year-old girl who presented to our hospital with a 1-month history of a swollen mass and progressive inability to completely flex her left index finger. The active flexion angle of the proximal interphalangeal joint was limited to 85°. A longitudinal incision of the flexor digitorum profundus tendon was surgically performed. The synovium inside and outside the flexor digitorum profundus tendon was completely removed. After the surgical excision, normal tendon gliding returned without recurrence by the 1-year follow-up. The active flexion angle of the proximal interphalangeal joint improved to 100°. To the best of our knowledge, this is the first case of synovitis affecting the flexor tendon and leading to limited flexion of a finger. The manifestation of a double ring sign on magnetic resonance imaging is quite characteristic. Early diagnosis and monitoring of the hyperproliferation and invasiveness of the synovial tissue are required. Surgical excision can be a simple and effective tool when necessary.

“…43 On MRI, FTS appears as a well-defined soft tissue mass with nonuniform low signal intensity on T1-and T2-weighted sequences. 44 On fluid-sensitive sequences, the low signal patterns within the lesion are typically stripe-like or irregular, compared with TSGCTs that have a more granular appearance. If increased cellularity or myxoid change are present, these may result in high T2 signal intensity.…”

Hand and wrist soft tissue masses may be classified as pseudotumors, benign neoplasms, or malignant neoplasms. The vast majority of hand lesions are benign. Consideration of the location of the lesion and its imaging characteristics often leads to a specific diagnosis. Pseudotumors discussed in this article are ganglion cysts, accessory muscles, and inflammatory lesions. True tumors are described according to their tissue type: nerve sheath tumors, adipocytic tumors, so-called fibrohistiocytic tumors, pericytic tumors, and vascular lesions. We also outline the imaging features of masses encountered in the hand and wrist.
