Whipple's disease (WD) is an uncommon multisystem condition caused by the bacillus Tropheryma whipplei. Central nervous system involvement is a classical feature of the disease observed in 20 to 40% of the patients. We report the case of a 62 yeards old man with WD that developed neurological manifestations during its course, and discuss the most usual signs and symptoms focusing on recent diagnostic criteria and novel treatment regimens.

A case of central nervous system actinomycosis is reported. A 33-year-old male complained of headache, vomiting and blurred vision lasting for eight days prior to admission. On examination, a right hemiparesis, as well an intracranial hypertension were detected. The cerebrospinal fluid showed mild lymphomononuclear hypercytosis. Necropsy disclosed three abscess in the cerebral hemispheres, in addition to moderate cerebral edema on the left side but without purulent leptomeningitis. Actinomyces filaments and granules were demonstrated in the cerebral and lung abscesses. The Brazilian literature on actinomycosis is reviewed and six published cases with nervous system involvement were found. Relevant clinical and anatomical aspects of the cases and of the present one are discussed.

A 6 month-old mulatto boy was admitted on account of acute gastroenteritis, malnutrition and dehydration. In the hospital, the child developed septicemia, and temperature reached up to 38.6°C. Despite intensive antibiotic treatment, the patient died 12 days after admission. Necropsy disclosed bilateral bronchopneumonia, bilateral fronto-parietal subarachnoid hemorrhage, and extensive necrosis of the inferior half of both cerebellar hemispheres. On histopathological examination of the necrotic cerebellar cortex, numerous sickled erythrocytes were observed in petechial hemorrhages and, in lesser quantities, inside capillaries. Lesions of the central nervous system in sickle cell anemia most often involve the cerebral cortex, and a single extensive cerebellar infarction as present in this case seems extremely rare. The pathogenetic mechanism of the necrosis is unclear, since thrombosis was not observed either in large blood vessels or in capillaries. Possible contributory factors were the infectious condition (septicemia), fever, and anoxia caused by the extensive bronchopneumonia.

Multiloculated hydrocephalus is a clinicopathological entity consisting of enlarged, loculated ventricles and paraventricular poroencephalic cavities. We present two cases of multiloculated hydrocephalus: one due to infectious process of central nervous system and the other consequent to a congenital malformation. Tomographic aspects of this condition that permit the diagnosis are stressed. The pathophysiology, the management and the prognosis are discussed according to the available literature.
