We present autopsy findings of a stillborn female infant at 20 to 21 weeks' gestation with neuroaxonal dystrophy. External examination showed features of fetal akinesia deformation sequence. Internal examination showed hypoplasia of the cerebellum, corpus callosum, and optic nerves, as well as nuclear cataracts. Light and electron microscopic examinations showed widespread axonal spheroids in the central and peripheral nervous systems. Gene sequencing failed to reveal PLA2G6 mutations, indicating that fetal neuroaxonal dystrophy presenting as fetal akinesia deformation sequence is genetically distinct from infantile neuroaxonal dystrophy and related disorders. In addition, placental examination showed α-fetoprotein-positive, eosinophilic, globular inclusions in the cytoplasm of a few villous macrophages. The significance of this novel histologic finding is unclear.
