Case contributed by A.Prof Frank Gaillard

Presentation

Non-specific symptoms.

Patient Data

Age: 70 years
Gender: Male
Modality: MRI

A small intracanalicular left sided nodule consistent with an acoustic schwannoma. 

Increased T2 signal in the middle cerebellar peduncles is a striking abnormality with a further region of high T2 signal in the splenium of the corpus callosum. 

Case Discussion

Limited clinical information is available about this patient, however according to the request card the diagnosis of FXTAS has been established, and imaging is consistent with this (including both major radiological criteria - MCP sign and high T2 in the splenium of the corpus callosum. 

For the sake of argument (specific history not actually provided) a typical history would be that the patient's grandson has been diagnosed with Fragile X syndrome some years earlier.
