Meningioangiomatosis without neurofibromatosis simulating encephalitis in neuroimaging.

Background: Meningioangiomatosis (MA) is a rare entity characterized by a focal lesion that affects the leptomeninges and the cerebral cortex.

Case Description: We describe a case of a 32-year-old man diagnosed with MA not associated with hamartomatous lesions or with type 2 neurofibromatosis. Magnetic resonance images (MRI) showed an extensive parieto-occipital lesion and another right frontal lesion, initially suggestive of encephalitis.

Comparative clinical and ultrasound study of egg-negative and egg-positive individuals from Schistosoma mansoni low morbidity endemic areas, and hospitalized patients with hepatosplenic disease.

Two hundred and twenty three subjects from a Schistosoma mansoni low morbidity endemic area and nine hospitalized hepatosplenic patients were submitted to stool test and clinical examination and abdomen ultrasound assessments. According to stool examination and ultrasound results, they were grouped as follows: G1 -- 63 Schistosoma mansoni egg-negative individuals; G2 -- 141 egg-positive patients and without evidence of periportal fibrosis; G3 -- 19 egg-positive patients with periportal echogenicity (3-6 mm); and G4 -- 9 hepatosplenic patients with periportal echogenicity (> 6 mm). Hepatomegaly detected by physical examination of the abdomen evaluated in the midclavicular line was verified in G1, G2 and G3, respectively, in 11.
