Abstract
Background and Purpose: Distension of the intracranial veins including intercavernous sinuses is a common finding in patients with intracranial hypotension (IH). Following four intercavernous venous communications have been described in the literature: the anterior, posterior and inferior intercavernous sinuses, as well as the basilar plexus. A distended inferior intercavernous sinus (IICS) may mimic a focal pituitary lesion on sagittal T1 images. The purpose of this study is to describe the frequency of enlarged inferior intercavernous sinus in patients with IH and controls.
