“…The sonographic appearance of pigmented villonodular synovitis is described as a hypoechoic synovial proliferation with hypervascularity visible on color Doppler sonograms. 15 The sonographic appearance of synovial osteochondromatosis is described as a periarticular or intra-articular mass containing multiple hyperechoic foci, some of which demonstrate distal acoustic shadowing. [16][17][18] The characteristic sonographic appearance of lipoma arborescens closely parallels that of other imaging descriptions and the arthroscopic appearance.…”

Three patients with lipoma arborescens of the knee joint were evaluated with high resolution ultrasonography. All patients demonstrated a hyperechoic, frondlike mass in the suprapatellar bursa with a large associated effusion. All had popliteal cyst formation without involvement by the mass. Dynamic compression and manipulation of the suprapatellar effusion demonstrated pliable and flexible nature of mass with bending and waving of the frondlike mass in real time. Comparison with MR imaging demonstrated similar extent, location, and morphology of the mass. The characteristic features of this lesion as well as its distribution in the knee joint can be demonstrated readily by sonography.

“…Findings include loculated joint effusion, complex heterogeneous echogenic masses, and thickened synovium. 13,14 These findings are nonspecific and may be seen in other causes of synovitis such as rheumatoid arthritis. US study has also been used to evaluate the results of intra-articular radiation therapy in known cases of PVNS.…”

Pigmented villonodular synovitis (PVNS) is a rare, benign, idiopathic proliferative disorder of the synovium that results in villous and/or nodular formation in joints, tendon sheaths, and bursae. The disease can be localized or diffuse. Patients with this condition typically present with symptoms of mild discomfort and associated stiffness of the involved joint; however, the spectrum of presentations is broad. Diagnosis of PVNS can be clinically difficult, and plain radiographs are usually nonspecific. Magnetic resonance (MR) imaging is a highly diagnostic modality in characterizing PVNS when it contains hemosiderin deposits exhibiting low signal intensity on all MR image pulse sequences. This article discusses the presentation, pathology, differential diagnosis, diagnostic modalities as well as various treatment options of PVNS.

In the diffuse form of pigmented villonodular synovitis, the transformed synovia invades local bone and cartilage, leading to destruction of the osseous and cartilage tissue. Secondary osteoarthritis and ultimately joint destruction is a result. Malignant development is under discussion. The knee is the most frequently involved joint, followed by involvement of the hip, which is well documented in several studies. This paper introduces a case of pigmented villonodular synovitis involving the hip. Its general diagnostic features and treatment options are introduced and discussed, including the role of reconstructive joint surgery in advanced cases of PVS. The key function of early diagnosis and treatment resulting in joint-salvaging procedures is emphasized.
