Congenital neuronal ceroid lipofuscinosis. A case report.

A case of congenital neuronal ceroid lipofuscinosis, a 9-day-old male child of Pakistani parents, is reported. Only 5 congenital cases have been described previously. The cerebral and cerebellar cortex showed extensive nerve-cell loss. Granular material with histochemical characteristics of ceroid-lipofuscin was deposited in neurons, macrophages and glial cells throughout the brain. Similar material was found in macrophages in the lymphoid system and in certain other organs. Ultrastructurally, the material was identical with that described in the infantile type of ceroid lipofuscinosis. It is pointed out that the metabolic exchange between the blood of the mother and the foetus is not sufficient to prevent the intra-uterine progression of the disease.
