Sporadic supratentorial hemangioblastoma with meningeal affection: A case report and literature review.

Background: Hemangioblastomas are vascular tumors, of benign behavior, that originate in the central nervous system. Supratentorial hemangioblastomas are extremely rare and are generally associated with Von Hippel-Lindau disease (VHL). The involvement of structures by contiguity, such as blood vessels or meninges, is something exceptional.

Intracranial hypotension secondary to spontaneous spinal cerebrospinal fluid fistula: Three case reports.

Spontaneous intracranial hypotension syndrome (SIH) is a rare condition. The main symptom is orthostatic headache, although other symptoms such as vegetative symptoms, meningism, or focal neurological deficits may appear. The most common cause is a cerebrospinal fluid leak, usually traumatic.

Glioblastoma with primitive neuronal component: A case report and considerations of fluorescence-guided surgery.

Background: Glioblastoma with primitive neuronal components (GB/PNC) is an extremely rare type of glioblastoma characterized by presenting histological and cytogenetic features of both entities. The mixed nature of these tumors limits the imaging diagnosis and supposes a therapeutic dilemma.

Case Description: We present the case of a 77-year-old female with a GB/PNC who is treated with surgery and adjuvant radiochemotherapy according to the STUPP protocol, where an abnormal uptake of 5-aminolevulinic acid (5-ALA) is evident during surgery in probable relation to the mixed nature of GB/PNC.
