Perforated neuroenteric cyst masquerading as congenital pulmonary airway malformation.

A 3-month-old child was presented with haemoptysis with respiratory distress. Imaging was suggestive of a cavitary lesion in the lung with surrounding consolidation. Diagnosis of a primary lung pathology like congenital pulmonary airway malformation was considered. Based on clinical suspicion and prior experience, a Tc-99m pertechnetate radionuclide study was performed, which clinched the diagnosis of foregut duplication cyst. Intraoperative findings confirmed the presence of a neuroenteric cyst. The child remains asymptomatic on follow-up awaiting neurosurgical intervention for the intraspinal component of the cyst.
