The purpose of our study is to describe shifting bone marrow edema in the knee as the MR imaging feature of intra-articular regional migratory osteoporosis of the knee. ⋯ In the absence of acute trauma or clinical suspicion of infection, a large area of bone marrow edema without a zone of demarcation may represent intra-articular regional migratory osteoporosis. Demonstration of shifting bone marrow edema on follow-up examinations suggests this diagnosis.

Case Reports
Unusual late sequel of ruptured distal tendon of biceps brachii mimicking a soft-tissue tumor.
We report a rare case of chronic, neglected rupture of the distal biceps brachii which presented with gradually increasing swelling over the left lower arm. Fine-needle aspiration cytology was reported as indicative of a soft-tissue neoplasm. Computed tomography and magnetic resonance imaging were unable to rule out a neoplastic mass. Final histopathology after surgical excision revealed a reparative process. ⋯ Such a presentation of ruptured biceps brachii wherein the clinicoradiological features are misleading and suggestive of a soft-tissue tumor is quite unusual.
