Abstract
Cerebral blood flow and oxygen metabolism were measured in a five-year-old boy with atypical Menkes kinky hair disease (MKHD) by using positron emission tomography (PET). The patient was diagnosed as having atypical MKHD because of low serum and urinary copper levels, and clinical symptoms. The CT revealed mild to moderate degrees of brain atrophy predominantly in the cerebellum. The PET demonstrated marked decreases of cerebral blood flow and oxygen metabolism in the cerebellum, brain stem and thalamus. These findings seem to reflect the neuropathological abnormalities observed in MKHD. PET seems to be more sensitive than CT in detecting abnormalities in the affected structures. However, because this case is atypical the question of whether typical cases show similar features on the PET remains.
