Cavum velum interpositum, cavum septum pellucidum, and cavum vergae: a review

Abstract

Introduction Anterior midline intracranial cysts may be found most often in three forms: cavum septum pellucidum, cavum vergae, and cavum velum interpositum. A single offering that reviews these entities is difficult to find in the extant literature. Therefore, the present review was performed. Materials and methods Various search engines and germane texts were reviewed for the terms cavum septum pellucidum, cavum vergae, and cavum velum interpositum. Results We report the findings of our search of the literature regarding these midline cystic structures. Conclusions A better understanding of the associated anatomy, embryology, and pathology of these cysts will assist the clinician who treats such patients.
