A case of aspergillosis associated with intralobar pulmonary sequestration.

We present a case of intralobar pulmonary sequestration (IPS) and pulmonary aspergillosis (PA) in a 32-year-old Japanese man. Immunological examination indicated an initial diagnosis of PA and an antifungal agent was administered. Since an abnormal chest shadow persisted, another causative lung disease was suspected to exist. Further inspection revealed the presence of IPS and surgical resection was performed. The symptoms of IPS are usually secondary to pyogenic infection; nevertheless, Aspergillus is a possible causative microorganism.
