Thrombotic thrombocytopenic purpura mimicking acute ischemic stroke.

Thrombotic thrombocytopenic purpura (TTP) is an autoimmune disorder characterised by thrombocytopenia, haemolytic anemia, fluctuating neurological deficits, fever, and renal impairment. This case report is about a young man who presented with acute onset right sided paralysis, dysarthria, and central facial paralysis, suggestive of cerebrovascular accident, but eventually diagnosed as TTP. In addition, the clinical presentation of TTP is discussed and some teaching points for the emergency physicians are emphasised.
