MR imaging features of bizarre parosteal osteochondromatous proliferation of bone (Nora's lesion)

The purpose of this study was to review the imaging findings of three patients with bizarre parosteal osteochrondromatous proliferation of bone (BPOP). The plain radiographs and MRI images of three patients with BPOP were obtained and retrospectively reviewed. In two cases, BPOP involved the feet. In one case BPOP involved the hand. In all three cases, plain radiographs showed a well-defined calcium containing mass adjacent to the cortical surface of the adjacent bone. The underlying bone appeared normal in all cases. On MRI, the lesion was of low signal intensity on T1 weighted sequences in all cases. On FSE T2 weighted and STIR sequences, the lesion was of high signal in all cases. The cortex, medullary cavity and adjacent soft tissues appeared normal in all cases. While BPOP is rare and often confused with a variety of both benign and malignant lesions, there are specific radiological findings that may help to distinguish BPOP from many of its mimickers.

Gluteal mass in a bodybuilder: radiological depiction of a complication of anabolic steroid use

Abstract. The use of anabolic steroids by bodybuilders is relatively common and associated with many side effects. Local side effects include tissue necrosis and soft tissue infection at the injection site. Systemic effects may be early epiphyseal closure in the immature skeleton, testicular atrophy, sterility, acne, gynaecomastia and liver disorders such as hepatitis. We report an unusual case of a bodybuilder who developed a large painful inflammatory soft tissue mass in his gluteal area. Multi-modality imaging showed direct evidence revealing the underlying cause of the mass being depot steroid injections.

Ollier's disease in association with adjacent fibromatosis

Olliers disease (enchondromatosis) is a nonhereditary disorder of mesodermal dysplasia. It is characterized by the presence of multiple enchondromas that typically affect the metaphyseal ends of bones. The association of Olliers disease with adjacent fibromatosis has, to our knowledge, not been previously described. We report a case of Olliers disease in association with soft tissue fibromatosis adjacent to the involved upper arm.
