INTRODUCTION Pigmented villonodular synovitis (PVNS) is a rare, benign proliferative disorder of the synovial membrane that typically presents in adults and affects a single joint. Multifocal PVNS is very rare, particularly in childhood. We reported a rare case of multifocal PVNS affecting over 20 joints in a child. CLINICAL PROCEDURE A 7-year-old female patient had a 6-month history of multi...

Pigmented villonodular synovitis (PVNS) is a rare, benign, proliferative disease of the synovial membrane of joints, tendon sheaths, and bursas. Joint aspiration typically yields hemorrhagic or xanthochromic/serosanguinous (brown, murky) fluid. We describe a case of PVNS that presented as an acute, painless, nontraumatic right knee effusion with clear synovial fluid on arthrocentesis. Initial m...

I n 2002 when he was 27 years old, our patient sought care for a 2-year history of right hip pain that he fi rst noted after jogging. Th e pain progressed to where he could not run. He saw his family practitioner, who thought it might be a hernia. Later, the pain progressed, and he was referred to an orthopaedic surgeon. He was referred to Baylor University Medical Center at Dallas for further ...

Pigmented villonodular synovitis (PVNS) is benign proliferative disorder of the synovium of unknown origin. PVNS is divided into intra-articular and extra-articular form which may present as i) diffuse or ii) localised/nodular form. It is commonly seen in knee joint but hip, ankle, shoulder, wrist & other joints can be involved. It is usually seen in young adults from 20-50 years of age. It is ...

Pigmented villonodular synovitis (PVNS) is a benign proliferative disorder primarily occurring in the large joints of the appendicular skeleton such as the knee and hip joints. We present an unusual case of PVNS involving the cervical spine in an adult. MR imaging showed an enhancing mass lesion arising from the posterior elements of the cervical spine and hyperintensity on the T2-weighted imag...

Pigmented villonodular synovitis (PVNS) is a benign aggressive disease that presents in either a localized (LPVNS) or diffuse (DPVNS) form. Arthroscopic synovectomy is the standard operative treatment for LPVNS, and when used to treat DPVNS, it is usually combined with an open posterior procedure. The purpose of this Technical Note is to report the technique that we have refined to allow for ar...

that usually arise in the hands and feet. On rare occasions, this tumor arises from the capsule or paraarticular soft tissue of large joints, such as the knee (1). These lesions should be differentiated from synovial chodromatosis, localized pigmented villonodular synovitis and other calcified lesions occurring about the joints. We report here on a case of intracapsular and paraarticular chondr...
