Tentorial dural arteriovenous fistula with perimedullary venous drainage-associated cervical myelopathy: illustrative case.

Background: Tentorial dural arteriovenous fistulas (DAVFs) with perimedullary venous drainage causing cervical myelopathy are very uncommon conditions with an extremely aggressive behavior. When the characteristic radiological clues are missing, the unspecific clinical picture may cause delay and make the diagnosis challenging.

Observations: Here the authors report a case of a 58-year-old man who developed progressive spastic tetraparesis and dyspnea with an extensive mild enhancing cervical cord lesion initially oriented as a neurosyphilis-associated transverse myelitis.

Anaplasic ganglioglioma: Cervical-dorso-lumbar leptomeningeal dissemination. About a case.

Gangliogliomas are well-differentiated, slow-growing tumors. The majority are gradeI of WHO. It appears predominantly in children and young adults.

Multiple filum terminale hemangioblastomas symptomatic during pregnancy. Case report.

Hemangioblastomas are low-grade, highly vascular tumors commonly associated with von Hippel-Lindau (VHL) syndrome and most often appearing in the cerebellum. They very rarely occur in the spinal nerve roots, and an origin in the filum terminale is exceptional with no instances of multiple hemangioblastomas of the filum terminale reported in the literature. Because of their vascular nature, these lesions can enlarge and become symptomatic in the context of the changes that take place during pregnancy, as has been noted with cerebellar hemangioblastomas.
