Pontine haemorrhage
acute haemorrhage within the pons causing a characteristic clinical picture.
The patient complains of a severe headache and rapidly becomes unconscious, and then develops periodic respiration, pinpoint pupils, loss of "doll's head" ocular movements and tetraplegia. There is no flaccidity and the patient may rapidly go into decerebrate posturing. Hypertension is the main cause of pontine haematoma. CT is the first examination of choice and shows the hyperintense haematoma usually occupying a large part of the pons, sometimes with intraventricular rupture within the first ventricle . There is usually no need for MR or angiography, unless a vascular malformation is suspected..
