Abstract:
Subarachnoid hemorrhage is uncommon in pregnancy and may be caused by intracranial aneurysms, arteriovenous malformations, venous thrombosis, or preeclampsia. We present an unusual case of subarachnoid hemorrhage in a term parturient where the bleeding originated from an extracranial source, namely a cervicothoracic arteriovenous malformation. This case highlights the challenge of diagnosing this condition when the initial presentation may be nonspecific, lacking in neurologic deficits, and confounded by the simultaneous presence of preeclampsia.
