Abstract

Headache during pregnancy and the postpartum period requires careful evaluation because physiological changes can

mask serious secondary causes. We present a case series of four obstetric patients with varied headache etiologies,

ranging from benign dehydration and migraine to secondary intracranial hypotension and cerebral venous sinus

thrombosis. Presentations occurred across antenatal and postnatal settings and included associated features such as

vomiting, bradycardia, and visual symptoms. Neuroimaging played a decisive role in differentiating primary from

secondary pathology, particularly MRI with venography in suspected venous thrombosis and characteristic structural

markers in intracranial hypotension. Management strategies differed substantially according to etiology, including

hydration therapy, migraine prophylaxis, and anticoagulation. Outcomes were favorable with timely multidisciplinary

involvement. This series underscores the importance of red-flag recognition, imaging selection, and coordinated

specialty care when evaluating headache in obstetric patients.

How strong is the evidence?

Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
