Giant carcinoid tumor mimicking pulmonary sequestration.

Abstract

A 42-year-old woman who previously underwent two consecutive thoracotomies for a lower lobe mass in her right lung was referred to our clinic for further management. Both procedures were abandoned due to excessive bleeding. Computed tomographic angiography demonstrated an infra-diaphragmatic systemic arterial supply of the mass similar to pulmonary sequestration. However the lobe had a normal venous drainage to the left atrium. Then a right lower lobectomy was undertaken through a hemi-clamshell incision, and histopathology revealed an atypical carcinoid tumor. The patient was discharged home after a satisfactory postoperative period. She still remains disease free at 14 months follow-up.
