Coarctation of the lateral ventricles/connatal cysts


Small bilateral frontal periventricular cysts just inferior to the superolateral angle of the frontal horns of the lateral ventricles


Synonyms for connatal cysts are coarctation of the lateral ventricles and frontal horn cysts.

These are cystic areas adjacent to the superolateral margins of the frontal horns of the lateral ventricles.

Though originally these lesions were believed to be the sequelae of ischemic insult, it is now believed that they represent a normal variant due to approximation of the walls of the frontal horns of the lateral ventricles. When the ventricular walls are close enough to touch each other it results in what sonographically appears to be a cyst.

Connatal cysts are located at or just below the superolateral angles of the frontal horns or body of the lateral ventricles and are mainly anterior to the foramina of Monro.

These cysts have been reported to resolve at follow-up studies.
