Man with Cerebellar Signs

Saturday, October 9, 2010
33 years old male with a a long history of unsteadiness, since childhood. Mentation was below average. Clinicians elicited 'past-pointing' and ataxia.

Identify this CT scan???


There are visible cerebellar folia. The 4th ventricle is large. The foramina of Magendie and Lushka are shown in one cut. The posterior fossa cisterns are visible. The pons and brain stem are grossly normal size. All of the diagnostic changes lie below the tentorium cerebelli.

  22. there is definitely cerebellar atrophy mostly in the anterior lobe and vermis, interestingly pons and medulla have a normal size. Although this can be spinocerebellar ataxia, the problem is which one there are far to many genotypes right now and doubt we can identify one by CT scan.

    WOnder if this is Fragile X syndrome as is an important cause of mental retardation in adult males. SHould exclude possibility of lond term treatment with phenytoin if he had hx of seizures
