Acute headache with a twist.

ABSTRACT

This case report follows the events of a 36-year-old woman who presented to a hospital five days post-partum with an acute severe headache and vomiting. Despite a normal initial computed tomography (CT) head scan, a CT venogram was done due to neurological deterioration and revealed hydrocephalus secondary to subarachnoid haemorrhage (SAH). We discuss the role of CT imaging in the diagnosis of SAH, the risks of current guidelines for lumbar puncture (LP) and describe other important differential diagnoses for headache in the postpartum patient.
