Central retinal vein thrombosis as an initial manifestation of heterozygous protein C deficiency: case report

The purpose of this paper is to report a case of central retinal vein thrombosis associated with isolated heterozygous protein C deficiency. Acute occlusion of the central retinal vein presents as one of the most dramatic pictures in ophthalmology. It is often a result of both local and systemic causes. A rare systemic cause is heterozygous protein C deficiency, and it usually occurs in combination with other thrombophilic conditions. This case highlights that isolated heterozygous protein C deficiency may be the cause of central retinal vein thrombosis and underscores the importance of its screening in young patients with this ophthalmologic disease.

Aspecto tumoral da cisticercose intracraniana: abordagem cirúrgica

The cerebral cysticercosis can produce intracranial hypertension by inflammatory obstruction of the basal cysterns or by expansive lesion in the cerebral parenchima or ventricular cavities. In the latter and in tumor cases the clinical picture is very similar and only after surgery can the etiology be determined. We present 11 operated cases of intracranial cysticercosis which presented the clinical picture of an expansive lesion. There were 7 females and 4 males with ages between 4 and 65 years. Nine patients were admitted because of headache, vomiting and visual disturbances suggestive of intracranial hypertension. One patient was admited with lymphocytic meningitis and another with focal seizures following hemiparesis. Five patients presented focal signs and six edema of the papilla. Epileptic manifestations were present in 45.5% of the cases. A plain X-ray films of the skull failed to reveal calcificatons, however signs of chronic hypertension were present in three cases. The electroencephalogram showed slow focal waves in 8 patients The spinal fluid examination revealed lymphocytosis in 4 cases, increased protein content in another 4 and complement fixation for cysticercosis was positive in 2 cases. The expansive lesions were localized by angiograph and ventriculography. In these the location was temporal in 4, frontal in 3, parietal in 2, in the third ventricle in one and in the fourth ventricle in another. At surgery we removed a large cyst from the cerebral parenchyma in six cases. Around the cyst a thick glial reaction was present. In the other cases the cyst was small but fixed to the ventricular trigone and produced dilatation of the inferior horn of the lateral ventricle. In two cases we removed a solitary intraventricular cyst from the third and fourth ventricles. In the two children operated upon there were several small hard cysts involving the cerebral parenchyma which displayed intense gliosis. There were no postoperative complications.

Astrocitoma frontal com metastase medular: registro de um caso e revisão da literatura

A case of a right frontal astrocytoma with spinal metastatic lesion in the region of the third dorsal vertebra is reported. The metastatic nodule was removed six months after the craniotomy. In the literature concerning to the dissemination of tumors cells is suggested that there is not a causal relationship between CSF seeding and operative intervention. Acess to the ventricular system or basal cisterns is of primary importance in the production of metastases.

Necrose cerebelar extensa na anemia falciforme: relato de um caso

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.
