BACKGROUND AND PURPOSE Assessing the response to treatment in infiltrative brain tumors by using lesion volume-based response criteria is challenging. We hypothesized that in such tumors, volume measurements alone may not accurately capture changes in actual tumor burden during treatment. We longitudinally evaluated volume changes in both normal-appearing supratentorial white matter and the bra...

Management of patients with arteriovenous malformations (AVMs) remains one of the most difficult problems in neurosurgery. Treatment of AVMs requires the efforts of a multidisciplinary team, including the vascular neurosurgeon, the interventional neuroradiologist, and the radiosurgery group. Other professionals are also essential to complete the team, such as a neurologist, psychologist, neuroi...

Hemangioblastomas of the central nervous system (CNS) are benign tumors that most commonly occur in the cerebellum, followed by the brainstem and spinal cord. 1 Supratentorial location is extremely rare. 2 CNS hemangioblastomas can occur sporadically or in association with von Hippel-Lindau disease. 2 Histologically, the tumors are composed of two main components: large and vacuolated stromal c...

Brain tumors hold second place in tumoral pediatric pathology and have a complex etiopathogeny. The authors describe the case of a child aged 2 years and 4 months with increased intracranial pressure, symptomatology accompanied by rapid deterioration of general condition. Head CT imaging examination showed intra-nevraxial replacement space process, supratentorial. Histopathological examination ...

Majority of ependymomas are infratentorial and intraventricular. Supratentorial and purely cortical extraventricular ependymomas are extremely rare and only five cases were reported. We report a 15-year-old male with left frontal cortical ependymoma. He had gross total excision of the lesion and was not given radioptherapy.
