Hemosiderotic synovitis: Highlighting the role of T2? weighted sequence in skeletal MRI

摘要

We report a rare case of spontaneous hemosiderotic synovitis of knee joint in an otherwise healthy young male player, with no associated findings of bleeding disorder, inflammatory arthritis or other systemic illness. The role of T2 weighted gradient recalled echo (GRE) (T2?WI) MRI sequence in skeletal imaging sticks out from this report. Close differential diagnosis of pigmented villonodular synovitis (a benign neoplastic condition) should be excluded by histological examination. Treatment aimed to prevent articular degeneration by prompt intervention.
