MR Imaging of Cerebral Aspergillosis in an Infant with Normal-Immunity: A Case Report

Cerebral aspergillosis is a rare condition, and like other opportunistic fungal infections, it most commonly occurs in immunocompromised patients. Because of the increasing use of chemotherapy in organ transplanta-tion, cases involving neoplasms, corticosteroid therapy, and cases of lymphoma and leukemia, the incidence of fungal infections in the brain has recently increased. Cerebral aspergillosis in an infant with normal immunity is a very rare condition, and has not been reported in Korea. We report the MR findings of this condition in an infant with normal immunity.

A Chondromyxoid Fibroma of the Fibula: A Case Report

Chondromyxoid fibroma is the least common benign bone tumor, accounting for less than 1% of all bone tumors. Pathologically, it is composed of varying proportions of chondroid, myxoid and fibrous elements. The most common anatomical site is the metaphyseal region of the long bone, and the typical radiologic appear-ance is a cortical expansile osteolytic lesion with a lobulated sclerotic margin, and septa. We report the plain and MRI findings of a relatively typical chondromyxoid fibroma occuring in the proximal fibula.
