Neurenteric cyst is a rare congenital anomaly that belongs to the spinal dysraphism spectrum. It is classically a disease of late childhood, with some rare reports of intrauterine and adult presentation. The increase in incidental antenatal diagnosis raises new management questions. We present a case of an asymptomatic combined intraspinal-posterior mediastinal neurenteric cyst. The cyst was diagnosed on antenatal ultrasound and was initially treated with image-guided aspiration in early infancy. However, the cyst recurred and the patient developed recurrent episodes of bacterial meningitis. Two-stage surgical resection was performed, although the infection prohibited complete excision. We caution against image guided aspiration of neurenteric cysts, and suggest a management algorithm based on the available literature.
