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.

The objective of this study was to describe the suprascapular nerve block using CT guidance and to evaluate the short- and medium-term efficacy in a range of shoulder pathologies. ⋯ In some patients with chronic soft tissue pathologies who do not respond to conventional treatment, a CT-guided suprascapular nerve block can provide safe short- and medium-term relief from pain and disability.

Giant cell tumor of soft parts (GCTSP) is an extremely rare lesion with an unpredictable behavior. Some patients are cured with a simple surgical excision whereas others will develop metastatic disease within a relatively short interval. To date, there are no consistently reliable criteria, either clinical or histologic, to separate the benign from more aggressive lesions. ⋯ The patient presented with a fungating skin and soft tissue mass and concurrent pulmonary nodules. The lesion recurred rapidly despite wide resection with negative surgical margins. Biopsy of the pulmonary lesions demonstrated metastatic disease.

Iliopsoas impingement syndrome, an infrequent complication of total hip replacement, has been rarely reported in the radiological literature. It follows chronic friction of the posterior aspect of the iliopsoas muscle and tendon against the acetabular cup, a piece of cement, or cup fixation screws. ⋯ Computed tomography (CT) is considered the gold standard imaging modality in evaluating iliopsoas impingement. We report a case of a patient in which the diagnosis was made by ultrasound and later confirmed by CT.
