“…If enhancement is observed, it is usually caused by inflammation and increased vascularity of the synovium. More often, delayed enhancement of the solid component is observed [5] , [6] . Although these features are classic for PVNS on imaging, it should be noted that cases present with variable signal intensity depending on the degree of hemosiderin deposition.…”

Pigmented villonodular synovitis is a benign but locally aggressive extra-articular tumor arising from the synovial membrane of tendons and bursae occurring near a joint space. Rarely, pigmented villonodular synovitis can involve the temporomandibular joint, which is emphasized in this paper. Diffuse and localized types have been described in the literature. The diffuse type involves the entire synovial membrane and infiltrates adjacent structures, which tend to be more aggressive and associated with a higher rate of recurrence when compared with the localized type.

“…Clinically, the TGCT usually occurs in all decades of life with predominance in the third or fourth decade. [7] The etiology of TGCT is controversial, someone has suggested that recurrent trauma and hemarthrosis may be the contributing factor. [8] Microscopically, the tumor is composed of monocyte, multinucleated giant cells and foam cells distributing in a fibrous stroma, presenting hemosiderin deposition.…”

Rationale:The tenosynovial giant cell tumor (TGCT) is a benign but locally aggressive tumor that arises from the synovial membrane of joints, tendon sheaths, and bursae. Although any joint can be affected, involvement of the temporomandibular joint (TMJ) was reported very rarely, and there is no relevant report on 18F-FDG PET/computerized tomography (CT).Patient concerns and diagnoses:We present here a rare case of diffuse-type of TGCT (D-TGCT) arising from the right TMJ in a 74-year-old woman. The patient was discovered a mass of the right temporal fossa during a head CT scan. However, she did not receive any treatment and was discharged from the hospital. She visited our institution again after 4 years with worsening headache and swelling of the right preauricular area. An enhanced CT demonstrated a 6.0 × 3.4 × 5.0 cm mass of mixed density involving the right TMJ, with evident enhancement and extensive erosion of adjacent bones. Magnetic resonance imaging (MRI) showed hypointensity in the solid part of the mass but high signal intensity in the cystic part or necrosis on T2-weighted images (T2WI). In 18F-FDG PET/CT images, the solid portion of the mass had increased FDG uptake with a SUVmax of 19.8. It was then diagnosed as D-TGCT by postoperative pathology.Lessons:The case report shows the imaging features of the TGCT, including CT, MRI, and 18F-FDG PET/CT, especially the typical hypointensity on T2WI. Careful preoperative examination and complete resection are the factors that lead to the optimal treatment of the TGCT.

“…MRI typically demonstrates a mass-like synovial proliferation with lobulated margins. 10 , 22 This may be extensive in the diffuse form or limited to a well-defined single nodule in the localized form. The signal characteristics include low-to-intermediate signal on T 1 weighted images, variable enhancement following gadolinium, 23 low-to-intermediate signal on T 2 weighted images with some areas of high signal owing to joint fluid or an inflamed synovium.…”

Polyarticular extension of pigmented villonodular synovitis to contiguous joints via pigmented villonodular tenosynovitis

Pigmented villonodular synovitis is an uncommon benign neoplastic process that affects synovial-lined joints, bursae and tendon sheaths. We describe polyarticular extension of pigmented villonodular synovitis across joints secondary to pigmented villonodular tenosynovitis. Given that treatment is required to prevent progressive destruction of the involved joint, tendon or bursa, radiologists must be vigilant for diffuse polyarticular or extrasynovial involvement to optimize patient care and initiate appropriate therapy.
