Synovial hemangioma of the hip joint in a pediatric patient

Abstract

Hemangiomas of the articular synovium are rare and commonly associated with recurrent joint swelling and painful limitation of motion. The knee joint is the most commonly involved site, with most patients diagnosed in the second to third decade of life. Although over 200 cases have been reported in the English-language medical literature, only three have originated within the hip joint, all of which were in adult patients reported in the surgical literature. We describe a histologically proven synovial hemangioma of the hip joint in a pediatric patient that invaded the femur, acetabulum, and adjacent soft tissues, with a detailed discussion of the differential diagnosis based on the radiographic and magnetic resonance imaging (MRI) findings.

Synovial haemangioma of the knee: an under recognised condition

“…As was observed in our patients, delays in the diagnosis and treatment of synovial haemangioma can lead to long-term consequences including cartilage erosion and degenerative joint disease [6,9,15]. Progressive joint destruction is believed to occur from intermittent bleeding into the joint resulting in inflammation and direct chondrotoxicity [9,15].…”

Juxta-articular Myxoma of the Hip: A Rare Pediatric Tumor

“…Differential diagnosis of JAM involving the hip includes pigmented villonodular synovitis, hemophilia, nonspecific synovitis, juvenile idiopathic arthritis, synovial (osteo)chondromatosis, lipoma arborescens, and synovial hemangioma. 13 Other pathologies that could involve a hip joint are slipped femoral epiphysis, osteomyelitis, leukemia, osteoid osteoma, Ewing tumor, and osteosarcoma. All these entities may have similar clinical findings, presenting as hip pain or a limp.…”
