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.
