title: Spontaneous subarachnoid haemorrhage due to coarctation of aorta and intraspinal collaterals: a rare presentation.
abstract: The occurrence of spontaneous subarachnoid haemorrhage (SAH) in association with coarctation of thoracic aorta and absence of intracranial aneurysm is a rare association. In spontaneous SAH, the predominant cause is intracranial aneurysmal rupture. This report describes a case of a 40 year-old male who presented with SAH and was incidentally diagnosed to have coarctation of aorta (CoA) with intraspinal collaterals on further work up. This case demonstrates the importance of detailed evaluation of patients with spontaneous SAH on whom common aetiologies have been ruled out.
