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. [ABSTRACT FROM AUTHOR]

Cavernous venous malformations are a well recognized major pathologic categories of vascular malformations of the nervous system usually an incidental finding on routine imaging. These lesions are relatively rare in spinal cord and whenever present can lead to severe neurological deterioration due to significant hemorrhage and consequent mass effect. We present two such cases of spinal cord involvement and in brief described their imaging feature. They need to be armed with the appropriate knowledge of how to recognize and timely intervene.
