Cysticercosis is the most ordinary parasitary disease involving the nervous system. The involvement of the spine is rare, ranging from 0.7% to 5.8%, and the intramedullary incidence is rather uncommon. We report the case of a 52-year-old female patient with intramedullary cysticercosis at the C4-C5 level, treated at the Neurology and Neurosurgery Service of Santa Casa de Belo Horizonte. The patient was operated with the complete exeresis of the lesion and had a good outcome. Forty-five cases of intramedullary cysticercosis were found in the literature review. We conclude that although it is a rare pathology, intramedullary cysticercosis should be included in the differential diagnosis of intramedullary lesions, mainly in cases of patients with previous diagnosis for neurocysticercosis and also of those who live in endemic areas.

Bilateral calcifications in the basal ganglia associated with neurological manifestations was diagnosed as Fahr disease for a long time. We present the cases of two patients with bilateral calcifications in the basal ganglia who presented hypoparathyroidism and extrapyramidal syndrome. Based on literature review we discuss the identity of Fahr disease and the relationship between calcifications in the basal ganglia and manifestations of endocrine system dysfunctions.

The authors report the case of a 50-year-old female patient with right orbital headache secondary to a giant intracavernous aneurysm, diagnosed as Raeder paratrigeminal neuralgia. The patient was surgically treated with internal carotid artery trapping together with brain revascularization (superficial temporal artery to a deep branch of the middle cerebral artery). The patient had an excellent outcome. The identity of the syndrome and the differential diagnosis are discussed based on literature review.
