[Congenital anomalies of the brain in computed tomography].
From June. 1987 to Dec. 1988, data was collected from 12 cases with Congenital Brain Anomalies. The cases involved 7 girls and 5 boys with ages ranging from 2 days to 15 years old. Abnormalities diagnosed were Cavum-septi pellucidi; Cavum vergae; Cystic dilated cavum; Cavum veli interpositi; Lissencephaly with dysgenesis of the corpus callosum; Dysgenesis of the corpus callosum associated the midline dorsal cyst; Holoprosencephaly, alobar type; Schizencephaly associated with Hydranencephaly; Encephaloclastic porencephaly; Severe hydrocephalus; Variant type of Dandy-Walker cyst with dysgenesis of the corpus callosum; Arnold-Chiari malformation. The patients were initially seen OPD primarily for seizures and other complaints such as nystagmus with visual impairment, hypotonia, facial anomalies, Yolk-sac tumor, prematurity, dyspnea and hydrocephalus. Among these, Holoprosencephaly was easiest to diagnose because it was combined with facial anomalies. However the others required evaluation by CT. CT offers very efficient diagnostic modality which is better than a Cranial Echo. It is also safer than the invasive angiography and not as expensive as MRI.
