Porencephalic congenital cysts with hydrocephalus.

Unlabelled: The therapeutic criteria according to tomographic findings are reviewed. 10 children, 6 male and 4 female, with porencephalic congenital cysts were studied. Early symptoms began within the first 6 months of life in 9 cases, and at the age of 5 years in 1. The most frequent symptoms were: seizures in 3; motor deficit in 5; retarded psychomotor development in 7; endocranial hypertension syndrome in 7; symmetric macrocrania in 7; paresis of the motor ocular nerves in 4. Preoperative studies: X-ray films-1 each patient-showed diastasis of sutures in 6 and cranial asymmetry in 2. Electroencephalograms-6 patients-were abnormal and diffuse in 3, hipsarrhythmic in 2, and focal in 1. CT-1 each patient-showed porencephalic cysts in all the patients; ventricular dilatation in 9; a single ventricle in 1, and a shift of the midline in 5. Postoperative studies: EEG, 1 each patient; CT, 1 each patient.

Surgical treatment: 8 patients underwent peritoneal shunts and 2 atrial shunts. Plastic surgery of the dysraphy was also performed. Postsurgical treatment: Rehabilitation and anti-convulsive treatment-4 patients. There were no deaths among the patients. The morbidity improved.
