A cavum velum interpositum is a
normal variaton which is often detected incidentally in asymptomatic
individuals. However, arachnoid cyst of the cavum velum interpositum is
extremely rare and may cause symptoms similar to those of a third ventricular
mass. On imaging, the main differentials of this cyst are; cystic dilatation of
the cavum velum interpositum, cavum vergae cyst, arachnoid cyst of the
quadrigeminal cistern, and epidermoid cyst. We present a case of an arachnoid cyst of the cavum velum interpositum
coincidentally associated with the cavum septum pellusidum and cavum vergae. The
cavum velum interpositum is a rare location for the arachnoid cysts. Accurate
diagnosis of the arachnoid cysts of the cavum velum interpositum is important
as they cause serious symptoms which can be reversed by surgical treatment.
