[Orbital neurenteric cyst. A case report and review of the literature]

Abstract

Introduction: Neurenteric cysts defined as a cyst lined by endodermal-type epithelium are extremely rare. We report a rare case of an orbital neurenteric cyst.

Case report: A 19-year-old female presented with an orbital cyst tumor that had cosmetic consequences. The signal of the cyst was not enhanced after administration of gadolinium on MRI examination. The patient underwent surgery due to the increase in size of the tumor. A complete cyst removal including the cyst wall through the inferior palpebral fold was performed. The histological examination confirmed the diagnostic of neurenteric cyst. The patient was discharged home in excellent condition.

Conclusion: This report discusses the clinical presentation, neuroradiological aspect, pathological findings and therapeutic consideration of the neurenteric cyst. We described a rare case of orbital neurenteric cyst. Due to the local recurrence rate observed after partial resection, the goal of the surgery should be a total resection of the cyst with the cyst wall.
