[Cerebral ischaemia secondary to non-bacterial thrombotic endocarditis as the presenting symptom of an ovarian tumour].

Introduction: In cancer patients, cerebrovascular accidents (CVA) are the most common complication occurring in the central nervous system after metastasis. One of its causations is non-bacterial thrombotic endocarditis (NBTE), which appears on rare occasions as the first symptom of the tumour. The clinical manifestations of NBTE are the result of multiple systemic embolism.

[Leptomeningeal carcinomatosis as presenting symptom of a gallbladder carcinoma].

Introduction: Meningeal carcinomatosis is rare accounting for 4-5% in autopsy of patients with solid tumors, and even less frequent, 1%, in its pure form without brain metastases. We report a case of psychosis symptomatic of a meningeal carcinomatosis as presenting manifestation of a gallbladder carcinoma. This clinicopathological combination has not been described previously.

[A case report of mixed, parenchymatous and meningo-basal neurocysticercosis].

Neurocysticercosis is the most common parasitic disease of the central nervous system. Its incidence diminished dramatically in the last decades in our country, but due to emigration from endemic areas is expected an increase in the next years. In spite of the new immunologic and neuroradiographic techniques, diagnostic of centeinty may be very difficult.
