Stroke Thrombolysis in the Context of a Pituitary Macroadenoma.

ABSTRACT

The presence of an intracranial tumour is a relative or absolute contraindication to stroke thrombolysis by most guidelines across the world. This is based on the risk of iatrogenic symptomatic intracranial haemorrhage related to the tumour. We present a patient where the decision to proceed with thrombolysis was complicated by an incidental finding of an intracranial tumour. The decision was made to proceed with thrombolysis. The patient had excellent functional recovery in the hours after administration and didn't suffer any intracranial haemorrhage. The evidence around excluding this patient group from thrombolysis is scant and mostly of low quality. Original randomised controlled trials or stroke thrombolysis excluded this patient group and there have been none since. Published case reports and series are heterogeneous in their conclusions regarding the risk of symptomatic haemorrhage following thrombolysis in patients with intra-axial and extra-axial neoplasms. Further studies may clarify guidelines.
