Results: Abdominal computerized tomography demonstrated a 48× 37× 33 mm, solid, vascularized, encapsulated, mostly cystic suprarenal mass with no calcification reported to be highly suspicious for neuroblastoma. The mass was completely excised. Gross pathologic examination revealed a well circumscribed spongy lesion that mimicked a lung tissue. On microscopic examination, a disorganized lung tissue that was composed of alveoli, alveolar ductus and bronchioles was seen. Normal adrenal tissue was not observed. Later, we learnt that the lesion's arterial blood supply was from the abdominal aort. Based on these findings, our diagnosis was intraabdominal extralobar pulmonary sequestration.
