Brain MRI demonstrates bilateral thalamic mass, predominant on the right thalamus, showing a high signal on T2 and FLAIR, an important mass effect on adjacent structures.
Echo Gradient T2 shows no calcifications or bleeding within the mass.
A NECT (not shown) demonstrates a bi-thalamic mass, responsible for a noncommunicating bilateral hydrocephalus by compression of the third ventricule. A ventriculo-perotoneal shunt is performed. The patient wakes up with left hemiplegia, aphasia, deglutation and respiratory disorders of central origin.
Brain MRI demonstrates bilateral thalamic mass, predominant on the right thalmus, which would rather be the reason why the patient had a left sided hemiplegia. Morphological aspect, perfusion profile and MRS are consistent with a low grade bilateral thalamic glioma.
