Abstract
This is the first description of a connatal case of adrenoleukodystrophy. The clinical picture consisted of severe psychomotor retardation, convulsions and hypsarrhythmia, but no obvious signs of adrenal insufficiency. Pathologically, the adrenals were small. The entire cortex was largely replaced by large round cells. Ultrastructurally, some cells in the adrenal cortex contained inclusions with electron-lucent clefts surrounded by a membrane. The anterior pituitary lobe could be demonstrated to have produced ACTH. The central nervous system showed extensive zones of demyelination in the brainstem, the cerebellum and the right-sided capsula interna. In the demyelinated areas there was sudanophilic breakdown and an intense gliosis. Ongoing demyelination could also be demonstrated by the chemical analysis. In the gray matter there were micropolygyria of the insular cortex and swollen nerve cells in the nucleus arcuatus. Ultrastructure revealed the type of inclusions in the microglia of the same type as in the adrenals, and a different type of inclusions in unidentifiable cells, possibly neurons. These latter inclusions consisted of loosely stacked lamellar material. The findings are interpreted as further evidence of storage taking place in this disease.
