Circular configuration of Torcular Herophili presenting as childhood headache

Abstract

Abstract The torcular herophili, also known as the confluence of the sinuses, has a highly variable anatomy and up to 9 different types have been reported in the literature. We describe a case of a circular configuration of the torcular herophili in a child who presented with headache in absence of other abnormalities. The torcular herophili embryologically develops from the anterior and middle dural plexus.The anterior dural plexus is joined posteriorly by the middle dural plexus forming the junctional area of the drainage of superior sagittal sinus, straight sinus and bilateral transverse sinus, thereby forming the primitive torcular herophili 2. We propose that the circular configuration of the torcular herophili may cause episodes of headache due to raised intracranial pressure secondary to venous congestion caused by this configuration of the torcular.
