Abstract
Multicentric glioblastomas (MGBM) arising in infra/supratentorial regions are uncommon lesions. The authors report a case of MGBM in a 61 year-old female patient, who presented a sudden onset of left hemiplegia. The magnetic resonance imaging (MRI) showed two expansive large lesions affecting cerebellum and thalamus, with strong contrast enhancement. The patient underwent resection of the cerebellar lesion. Microscopy revealed a high grade glial neoplasm exhibiting high mitotic index, areas of necrosis and microvascular proliferation. The neoplastic cells showed positive immunoexpression for glial fibrillary acidic protein (GFAP). The morphological findings were consistent with glioblastoma (GBM). The patient was referred to radiotherapy, with discrete signs of tumor regression after a 60-day clinical follow-up.
