Unusual magnetic resonance imaging appearance of multiple cystic lesions in glioblastoma multiforme.
The differential diagnosis of multiple ring-enhancing intraaxial lesions     includes neoplastic, infectious, inflammatory, demyelinating and vascular     lesions. We report a case of a 41-year-old man who presented with a brief     history of left lower extremity weakness and sensory loss. Magnetic resonance     imaging demonstrated multiple ring-enhancing lesions in the right frontal and     parietal lobes. Neuroradiology interpretation was felt to be unlikely for a     neoplastic process. The patient underwent stereotactic brain biopsy, which was     diagnostic for glioblastoma multiforme. This case demonstrates the importance of     histological confirmation of intraaxial brain lesions whenever feasible. The     course of his disease and treatment are discussed and the literature reviewed.
