RT Journal Article SR Electronic T1 Thrombotic thrombocytopenic purpura: a true haematological emergency JF Emergency Medicine Journal JO Emerg Med J FD BMJ Publishing Group Ltd and the British Association for Accident & Emergency Medicine SP 701 OP 702 DO 10.1136/emj.2008.060434 VO 25 IS 10 A1 Bedi, N YR 2008 UL http://emj.bmj.com/content/25/10/701.abstract AB There are so few true haematological emergencies that they are often way down the list as a differential diagnosis. Those that do exist, however, can prove devastatingly fatal if left untreated and a case is presented of one such possible diagnosis, thrombotic thrombocytopenic purpura, which falls into the remit of many possible presenting conditions. Particularly prevalent in young adults, this condition must always be thought of in any patient presenting with confusion, renal impairment, fever or other neurological abnormalities.
