Abstract:
Cerebral venous thrombosis (CVT) is an uncommon occurrence, but it carries significant morbidity.1 CVT symptoms overlap with other common emergency department conditions, and it requires a specific neuroimaging for accurate detection, making this diagnosis a significant challenge for emergency clinicians. We present a case of a 20-year-old postpartum woman with a history of a post-dural puncture headache following a spinal block with worsening headache and disequilibrium. She was found to have a cerebral venous thrombosis on non-contrast head CT and CT venogram of the head. Her course was uncomplicated with appropriate symptom control while on anticoagulation. We review her CT imaging findings and provide a brief review of the current recommendations and literature on CVT.
Topics:
Cerebral venous thrombosis, empty delta sign, CT venogram, headache, dural sinus thrombosis.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
