[Intralobar sequestration associated with pulmonary aspergillosis].

A 49-year-old man with a cough productive of black sputum was admitted to our hospital. A chest CT scan was done. Cystic, estatic changes, and intra-capsula fluid surrounding an enhanced wall in the right S10 were seen. Aspergillus niger was detected by sputum culture. Aortic angiography showed that an aberrant artery originated from the inferior diaphragmatic artery and penetrated the right S10. The preoperative diagnosis was lung sequestration associated with aspergillosis. The operative procedure included right lower lobectomy and ligation of the aberrant artery. Postoperatively, Pryce-type intralobar sequestration infected with aspergillus was diagnosed. Microscopically, the parenchyma was distorted and chronic inflammation was present. Hyphae of aspergillus were found within the lumen of the cyst.
