Arteriovenous malformation mimicking recurrent medulloblastoma.

Academic Article


  • Magnetic resonance imaging (MRI) is becoming the method of choice for evaluation of central nervous system tumors. However, the sensitivity of this modality raises concern that new lesions in patients previously diagnosed with a brain tumor may not necessarily represent recurrent disease. We report a patient previously treated with surgery, radiotherapy, and chemotherapy for a medulloblastoma who developed a new lesion in the floor of the fourth ventricle. Histologic review following excision revealed an arteriovenous malformation.
