RESUMO
Control CT assessments of the brain of 15 alcohol dependent patients who showed an improvement in their clinical state were performed after a mean of 16 months. A partial decrease of the widening of cerebral sulci and the third ventrical was noticed. Also, the neuroradiological pictures of the vermis and cerebellum were seen to improve in most patients.

Shearing injuries, also called diffuse axonal injuries, are a special kind of severe head trauma, usually caused by a motor vehicle accident, in which disruption of white matter axons takes place. Twelve cases of shearing injuries were diagnosed by computed tomography (CT). The typical CT findings were small hemorrhagic lesions in the cerebral white matter, most often in cerebral hemispheres and internal capsules. In most patients, hemorrhagic foci were multiple. Single lesions were found in only two patients. Features of brain edema were found in eight of ten early studies, and subarachnoidal hemorrhage only in three. Two patients also had subdural hematomas. CT appearance of the shearing injuries is characteristic, especially in connection with clinical data indicating a history of head trauma and severe state of the patient.

308 CT scans of the head in children below 3 years of age were analysed. 70% of children were younger than 1 year. The most common findings in this age group were subdural effusions (usually no wider than 10 mm) and hydrocephalus. The authors conclude that the indications to CT scan should be more rigorous because of the high dose of the ionizing radiation applied. Ultrasonography should be the initial investigation in the children with persistent fontanellae+ as it has a similar diagnostic efficiency without harmful effect to the child body.
