Preoperative magnetic resonance imaging revealed a strong enhancing mass in the left frontal lobe extending to the cingulate gyrus. Adjuvant radiation therapy and chemotherapy were given after gross total resection of the tumor. Histolog...
متن کاملGanglioglioma with glioblastoma component.
Ganglioglioma with a glioblastomatous component and high-grade atypia of neuronal cells are extremely rare findings. In this paper, we report the case of a 60-year-old man who presented with a tumor of the left temporal lobe. Hematoxylin-Eosin stained slides revealed a complex tumor with features of glioblastoma and marked atypia of neuronal cells. Glial cells were highlightened by antibodies t...

Desmoplastic infantile gangliogliomas (DIGs) are rare intracranial, cystic tumors, usually detected within the first 2 years of life. Histologically, these tumors are characterized by intense desmoplasia and a divergent astrocytic and neuronal differentiation. Less than 60 well-documented cases of this extremely rare tumor are reported in the literature. We present the case of a 10-month-old ma...
