title: A pathological study of a peripheral nerve in a case of neonatal adrenoleukodystrophy.
abstract: The pathological findings for a sural nerve biopsy specimen in a case of neonatal adrenoleukodystrophy are described. The density and total number of myelinated fibers in the patient showed no significant changes compared with controls. On electric microscopy, however, thickness of the myelin was smaller in the patient than in controls. Some linear or trilamellar inclusion bodies were found in Schwann cells and fibroblasts, similar to those found in X-linked adrenoleukodystrophy. Büngner's bands were also seen on electron microscopy, and myelin ovoids and balls were seen in teased fibers. These results show that a sural nerve biopsy is useful for the diagnosis of neonatal adrenoleukodystrophy. We suspect that axonal or neuronal degeneration occurs with changes in myelin in neonatal adrenoleukodystrophy.
