High density on computed tomography in infantile Krabbe's disease: a case report.

In a child with a compatible clinical presentation and course of illness, Krabbe's disease was proven by white blood-cell galactocerebrosidase estimation in the homozygous range. A CT head scan performed at five months of age revealed symmetrical high density in the thalami, posterior limbs of the internal capsules and corona radiata. It also showed low density in the deep white-matter of the cerebral and cerebellar hemispheres and minor cerebral atrophy. Similar CT findings have been recorded in four other cases of infantile Krabbe's disease, and the authors consider that they are sufficient to alert the clinician to the probability of this diagnosis when the clinical signs are appropriate.
