Case Study June 2010

A 53-years-old man was admitted to the hospital because of progressive gait and cognitive disturbances. Approximately 15 days before admission, he began to develop progressive trouble to walk and had several falls at home. Concomitantly he had impaired comprehension and difficulty with word finding. He developed also apathy and urinary incontinence.

Since 10 years, the patient presented several transient relapsing diarrhea episodes. He underwent surgery 4 years ago for a non cancerous tumour of the large intestin (deep lymphocytic infiltrate).

On examination during the admission there was dysarthria, subcortico-frontal cognitive impairment and gait ataxia without limb weakness.

Magnetic resonance imaging (MRI) was performed after injection of gadolinium and showed enhancement of tumoral lesions in the basal ganglia predominent on the left side (arrowheads) corresponding to bilateral FLAIR hypersignal (arrows).
