Extralobar Pulmonary Sequestration in Adrenal Mimicking Neuroblastoma: A Case Report

Abstract

Background: Extralobar pulmonary sequestration (ELS) is a malformation composed of bronchopulmonary tissue outside the lungs that is discontinuous from the main tracheobronchial tree. ELS can present as a suprarenal space occupying lesion. Case Report: A 1-day old girl presented with a right supra-adrenal mass, first detected in-utero at 34 weeks. The differential included congenital neuroblastoma, but the urinary VMA was normal. At resection, there was lung tissue composed of dilated and tortuous bronchioles lined by columnar epithelium present in a back- to- back arrangement along with thick-walled vessels, features of an ELS with congenital pulmonary airway malformation type II. Conclusion: ELS enters the differential diagnosis of neonatal suprarenal masses with normal urinary catecholamines, and can have the morphology of a type II congenital pulmonary airway malformation.
