Abstract
Pigmented villonodular synovitis (PVNS) is a synovial proliferative joint destructive disease; hip joint is a rare localization of the lesion. We report a 24-year-old worker who admitting to emergency service with an unusual complaint of locked hip joint. Plain radiographs showed normal joint space without any intraarticular bony loose bodies. Magnetic Resonance Imaging (MRI) showed intraarticular synovial nodular mass at a size of 3 centimeters at the medial side of the femoral head and neck junction. Hip arthroscopy was performed 3.0x2.4x1.6 cm yellow-brownish colored pediculed synovial nodular mass excised. Pathological diagnosis was confirmed as PVNS. Excision of the mass allows prompt resolution of the symptoms and a quick return of the patient to daily living activity. There was no sign of recurrence at 36 months of follow-up with MRI and no any chondral lesion was observed at radiology. PVNS can occur acute locking of the hip joint is a very rare symptom which can require an emergency arthroscopic surgery. In case of proper patient selection and prompt diagnosis, early arthroscopic synovectomy and resection of the diseased synovia seems to be effective for preventing recurrence and development of secondary osteoarthritis of the joint. LPVNS should be kept in mind for differential diagnosis at locked joints.

We report a 24-year-old male who was admitted to the emergency department with an unusual complaint of locked hip joint. Magnetic resonance imaging (MRI) showed a 3-cm intra-articular synovial nodular mass and a 3.0x2.4x1.6-cm yellow-brownish colored pediculed synovial nodular mass was excised with hip arthroscopy. Pathological examination confirmed the diagnosis of pigmented villonodular synovitis. Excision of the mass allowed prompt resolution of the symptoms and there was no sign of recurrence at 3-year follow-up.
