[Porencephalia vera in autopsy specimens from the Department of Pathological Anatomy, Medical Academy, in Białystok 1976-1985].

Morphological and statistical analysis of true porencephaly based on 2793 autopsies of children aged up to 18 years showed 12 cases of porencephaly, accounting for 0.43% of the autopsy material, and 5.2% of all anomalies of the central nervous system in this age group. The greatest number of porencephaly cases (6) was in the age group 3-18 years. The anomaly was twice as frequent in boys (8 cases) than girls (4 cases). Nine cases of porencephaly showed coexistence of other developmental anomalies (75%) mainly with those of central nervous system, especially microecephaly, congenital hydrocephalus, which could indicate a genetic determination of the anomaly. The most frequent associated neurological singn in porencephaly was psychomotor underdevelopment.
