Global cerebellar hypoplasia

Case contributed by Dr Hidayatullah Hamidi

Presentation

Ataxic gait since childhood

Patient Data

Age: 20 years
Gender: Female
MRI

The cerebellum is globally reduced in size with widening of the cerebellar sulci. The supratentorial brain, brainstem and cervical cord appear unremarkable. 

Case Discussion

The normal shape of the cerebellum with global volume reduction is seen, consistent with global cerebellar hypoplasia; a type of congenital morphological cerebellar abnormality. An identical appearance can be seen in diffuse cerebellar atrophy, however, the long-standing history suggests that this is hypoplasia. Only long-term imaging showing stability over an extended time period can categorically distinguish between these two entities.
