Neuroimaging features of neurenteric cysts: analysis of nine cases and review of the literature.

Abstract

The diagnosis of NE cyst should be considered when imaging studies reveal the presence of a lobulated IDEM or an exophytic intramedullary cystic mass, especially in association with anterior spina bifida or other vertebral anomalies. MR can uniquely confirm the cystic nature of these masses and is the method of choice for their imaging investigation. Because cyst recurrence can occur, MR should also be used for long-term patient follow-up.
