A 51 year-old man presented with severe nausea. While in the hospital, he was noted to have episodes of shaking of the arms and would not respond to verbal stimuli. An urgent head CT scan was ordered, followed by emergency neurosurgical intervention and a subsequent MRI scan. |
Craniopharyngioma.
Axial CT scans. The most obvious abnormality in these scans
is the presence
of acute hydrocephalus, as evidenced by the enlarged temporal horns, the transependymal edema and the absence of sulci
over the convexities. If one looks closely, one can see a subtle
abnormality in the region of the anterior third ventricle. The
presence of an abrupt change in mental status due to acute
hydrocephalus is a neurosurgical emergency requiring urgent
ventricular drainage or shunting. In this case, an MRI scan was needed to determine the cause of the hydrocephalus. |
