Abstract:
This is a case report of a 55-year-old male, who was admitted due to right-sided sensorimotor deficits and one-and-a-half syndrome He had snorted 5 g of amphetamine over 24 h two months prior to admission. He was normotensive on admission. A CT brain scan showed left pontine haemorrhage, but a CT angiogram showed no vascular malformations nor vessel beading, and a two-month follow-up MRI showed no vascular malformations nor tumours. To the best of our knowledge, this is the fifth published case of pontine haemorrhage, and the first published case of one-and-a-half syndrome related to amphetamine abuse.
