An 8-month-old male infant who presented in the neonatal period with failure to thrive, bilateral pleural and pericardial effusions, and hepatic insufficiency characterized by elevated liver functions tests and hypoalbuminemia was found at autopsy to have an unusual combination of olivopontocerebellar atrophy (OPCA), micronodular cirrhosis, and renal tubular microcysts. Metabolic evaluation was significant only for elevated urine dicarboxylic acids. In the brain, sections from the cerebellum showed marked atrophy of folia most severe in the vermal and paravermal regions. In addition, mild neuronal loss was present in the basis pontis and inferior olivary nuclei accompanied by gliosis. Residual Purkinje cells in the cerebellar hemispheres exhibited greatly expanded and swollen arbors, which ultrastructurally were found to contain densely packed membranous cytoplasmic body-like inclusions that had the appearance of unwinding, lamellar coils. Review of the literature shows that this constellation of findings has been associated with carbohydrate-deficient transferrin. This biochemical marker along with the distinctive clinical presentation and pathological features clearly delineates a unique subset of OPCA.
