Anaplasic astrocytoma with exophytic growth in Sylvian fissure in a pediatric patient: a case report

Abstract

Gliomas are the most frequent supratentorial intracranial tumors in the pediatric population. Usually, they are intra-axial lesions with a characteristic image pattern, however, there are few reported cases of gliomas with exophytic growth. There are no previous reports in the literature of gliomas with exophytic growth in the Sylvian fissure. Fourteen year-old female patient who started with seizures. In imaging studies, a neoplasic mass with an exophytic portion in the left Sylvian fissure was found. Macroscopically, total resection was performed, definitive diagnosis was anaplastic astrocytoma. She presented recurrence and is currently receiving adjuvant treatment. Supratentorial gliomas with exophytic growth are extremely rare. We report the first case in the pediatric population, and we consider it is important to know its imaging and macroscopic characteristics for its initial management and to take it into account as a differential diagnosis of exophytic lesions.

A Rare Case of Anaplastic Astrocytoma

“…Most of the primary brain tumors are located in the supratentorial region of the brain, and it is not common to see tumor growth on deep brain structures such as the posterior corpus callosum. Sometimes brain lesions and tumors are so difficult to identify and diagnose because of the construction of visuospatial perception, attentional capacity impairment, apraxia, and maybe the only presenting symptoms [3,4,5].…”
