| ABSTRACT |
|
The authors report a case of rostral mesencephalic dysfunction due to obstructive hydrocephalus secondary to periaqueductal tumor who suffered multiple shunt failures and shunt revision. This patient presented with clinical syndromes, including akinetic mutism and diencephalic autonomic epilepsy. He had computed tomography(CT) and magnetic resonance(MR) findings of dilatation of ventricular system with periaqueductal tumor. The anatomical substrates of clinical findings are reviewed. A discussion of the probable mechanism proposes that dilatation of 3rd ventricle and rostral aqueduct sufficiently explains the entire syndrome. |
