    abstract = "A previously healthy 43-year-old man presented with coital thunderclap headache. A brain CT scan revealed a perimesencephalic subarachnoid hemorrhage (PMSAH). Digital subtraction angiography (DSA) showed a severe basilar artery vasospasm without underlying aneurysm (Figure 1). Under nimodipine treatment, the vasospasm resolved gradually. At a 1-month follow-up, a high-resolution (3T) MRI (HR-MRI) uncovered a primitive left basal vein of Rosenthal (BVR) draining to the lateral mesencephalic veins instead of the Galenic system.1 © American Academy of Neurology."
