A 35-year-old woman, gravida 5 para 3, presented to the emergency department 9 days after a cesarean delivery with a new-onset headache, hypertension, and hyperreflexia. Formal urinalysis did not demonstrate proteinuria. Computed tomography of the brain demonstrated bilateral parietal subarachnoid hemorrhages. The patient was subsequently transferred to a tertiary care hospital where she underwent magnetic resonance imaging and computed tomographic angiography that were not suggestive of intracerebral aneurysm, arteriovenous malformation, sinus thrombosis, or angiopathy.
