Candida osteomyelitis is an uncommon complication of immunosuppressive therapy. Its radiographic manifestations are similar to those of other relatively indolent infectious agents. We report the CT and MR findings in a patient who developed this condition following treatment for acute myelogenous leukemia, and review the imaging literature covering similar cases.

Chondroid lipoma is a recently described benign tumor of adipose origin which, pathologically, mimics myxoid liposarcoma and myxoid chondrosarcoma. This tumor typically presents as a well-defined mass in the superficial tissues of the extremities. In this report, we present the magnetic resonance imaging (MRI) appearances of a pathologically proven chondroid lipoma. To our knowledge, this is the first report of any imaging findings associated with this tumor.

Our data using MR imaging suggests that fat pad elevation in the presence of recent trauma is frequently associated with a fracture. The size of the effusion, anterior/posterior fat pad elevation, or a combination of both does not correspond to the likelihood of an underlying fracture. MR imaging reveals a broad spectrum of bone and soft tissue injury beyond that recognizable on plain radiographs as demonstrated by all patients in this study.

Osteosarcomas arising in irradiated tissues are uncommon but important complications of radiotherapy. Radiation-induced osteosarcomas generally occur 3-30 years after exposure and are most common after radiotherapy for cervical or breast carcinoma. These tumors are usually rapidly growing, extremely painful, and histologically high grade. In this paper, we report two cases of high-grade post-radiation osteosarcoma of the scapula. Despite being almost identical radiologically and pathologically, one case had a typical clinical presentation whereas the second case had two unusual features, being non-painful and arising in a field initially irradiated for bronchogenic carcinoma.
