[Intralobar Sequestration Associated with Aneurysm of the Aberrant Artery and Aspergillus Infection: Report of a Case].

A 32-year-old man was referred to our department for surgery because of recurrent pneumonia. Aspergillus fumigatus was detected in his sputum culture at the first visit. We started antifungal therapy one month before surgery. His chest radiograph showed an infiltrative shadow in the right lower lobe, and chest computed tomography (CT) showed an infiltrative shadow and large and small cystic changes in the right lower lobe. CT angiography (CTA) revealed two anomalous arteries supplied by the aorta that drained into the right lower lobe. An aneurysm with a diameter of 25 mm had formed in one anomalous artery. Based on these findings, intralobar pulmonary sequestration with Aspergillus infection and an anomalous artery forming an aneurysm was diagnosed. In addition, we embolized the aneurysm of the anomalous artery. After embolization, right lower lobectomy was safely performed. The patient was discharged on the 15th post-operative day with no complications.
