title: White matter attenuation and megalencephaly.
abstract: The computed tomogram of a 6 month old girl with familial megalencephaly showed widespread attenuation throughout the white matter. She continued to be developmentally and neurologically normal. Her scan at age 3 years was normal apart from the megalencephaly. A tentative explanation for this unusual series of events is offered.
