Total Agenesis of Superior Sagittal Sinus and Falx Cerebri in a Patient Who Has a Subacute Subdural Hematoma Crossing Midline: Case Report

Abstract

BACKGROUND AND IMPORTANCE: Anatomic variations of the superior sagittal sinus (SSS) and falx cerebri (FC) are uncommon in that agenesis of these structures is extremely rare. We report an extremely rare anatomic variation, total agenesis of the SSS and FC, and briefly discuss it from the anatomical, embryological, radiological, and clinical perspectives.
