Synovial hemangioma of the knee joint : magnetic resonance imaging findings

BACKGROUND: Synovial hemangioma is benign tumor of the joints and is seen relatively rare. The most affected joint is knee but should also be seen in other joints. The disease is usually symptomatic. They are classified as juxta-articular haemangioma, intra-articular haemangioma or an intermediate type of hemangioma with intra- and extraarticular components. CASE REPORT: A 19-years-old male patient presented with swollen and painful knee. The laboratory findings and physical examination were normal. MRI demonstrated a large lesion that was filling the suprapatellar bursa. CONCLUSIONS: All radiologic examinations should be used in diagnosis but magnetic resonance imaging is the non-invasive method and excellent modality in the evaluation of soft tissues. In this paper, a 19-year-old male patient with the diagnosis of synovial hemangioma is reported and its radiologic findings are mentioned.
