Aneurysmal subarachnoid haemorrhage in a patient with thyrotoxicosis

Abstract

A case of subarachnoid haemorrhage secondary to rupture of an intracranial aneurysm occurring in a patient with new-onset, frank thyrotoxicosis is described. This unusual case highlights the dilemma of whether to continue beta-blockers such as propanolol for frank thyrotoxicosis, or whether to assign higher priority to maintaining adequate cerebral perfusion pressure in established ischaemic deficit due to vasospasm. In a complicated case such as this, the Maudsley Mentation Test score and perfusion CT scanning are two useful adjuncts for the early detection and evaluation of the course of ischaemic deficit.

Key words:

• Subarachnoid haemorrhage
• thyrotoxicosis
• delayed ischaemic neurological deficit
