Medulloblastoma is a relatively common intracranial neoplasm in childhood, but is a rare condition in adult group. This tumor has a well-known tendency to seed along cerebrospinal fluid pathways; however, extraneural metastases are uncommon and have typically been associated with a fatal outcome. When extracranial metastases occur, most common site of involvement is bone (80%), especially pelvis, long bones and spine. Radiographically, blastic (sclerotic) metastases are most common (60%), but lytic (35%) and mixed patterns (5%) also do occur [Clin. Imaging 15 (1991) 286]. In this paper we present a case of medulloblastoma metastatic to bone involving almost the whole skeleton and describe the magnetic resonance appearance, with emphasis on the imaging findings of mixed (both lytic and sclerotic) forms. © 2002 Elsevier Science Ireland Ltd.
