Arteriovenous fistula of the filum terminale masqueraded as a failed back surgery syndrome - A case report and review of literature.

Background: The filum terminale arteriovenous fistulas (FTAVFs) are a very rare type of spinal vascular malformation. Clinically, these lesions could present with a progressive ascending myelopathy also called FoixAlajouanine syndrome. Due to the rarity of these vascular malformation, some can be misdiagnosed, submitted to unnecessary spinal surgery, and even masqueraded as a failed back surgery syndrome.

Giant Malignant Peripheral Nerve Sheath Tumor of the Scalp: Case Report and Review of the Literature.

Background: Malignant peripheral nerve sheath tumors (MPNSTs) are rare nervous system tumors that rarely appear on the scalp. About half of the scalp MPNSTs described in the literature have reached giant dimensions at the time of diagnosis. The surgical treatment is the gold standard for this type of tumor.

Fourth ventricle neurocysticercosis: A case report.

Background: Neurocysticercosis (NCC) is the most common helminthic disease of the nervous system in humans and it is caused by the larvae of the pork tapeworm, . We present a case of microsurgical removal of a fourth ventricle NCC cyst combined with an endoscopic third ventriculostomy (ETV) to treat hydrocephalus.

Case Description: A 36-year-old woman presented to the emergency room with headache and decreased visual acuity over the last 4 months.

Genetic Variants Underlying Risk of Intracranial Aneurysms: Insights from a GWAS in Portugal.

Subarachnoid hemorrhage (SAH) is a life-threatening event that most frequently leads to severe disability and death. Its most frequent cause is the rupture of a saccular intracranial aneurysm (IA), which is a blood vessel dilation caused by disease or weakening of the vessel wall. Although the genetic contribution to IA is well established, to date no single gene has been unequivocally identified as responsible for IA formation or rupture.

Schwannoma of the Fourth Ventricle: The Eighth Case Report.

Objective: We report an uncommon case of a surgical resection of a fourth ventricle tumor in an adult that proved to be a schwannoma.

Methods: A 53-year-old man presented with a 1.5-year history of gait unsteadiness and vertigo and a few-week history of headache, emesis, and neurogenic dysphagia.

Rupture of middle fossa arachnoid cyst simulating new-onset migraine with aura.

Arachnoid cysts represent a common, innocent, finding in routine neuroimaging of headache patients. We present the first report of symptomatic migraine with aura caused by the spontaneous rupture of a middle fossa arachnoid cyst into the subdural space. Brain imaging enabled an accurate diagnosis and, subsequently, adequate surgical management.
