We herein report a case of @entity1576 caused by acute exacerbation of undiagnosed @entity401 ( @entity401 ). A 76-year-old @entity1 underwent two subsequent operations, cholecystectomy and resection of @entity362 in the neck, under general anesthesia at an interval of 12 days. Although the postoperative course of the first operation was uneventful, the @entity1 abruptly developed @entity1576 on the 4th postoperative day (POD) of the second operation. Although @entity134 therapy was transiently effective to improve oxygenation, @entity1576 was gradually deteriorated. She died on the 25th POD. She had a past history of right upper lobectomy for @entity6437 resulting from @entity3616 in another hospital 4 years ago. The follow-up CT performed in this hospital demonstrated subtle foci of ground-glass opacities in the left lung; however, no diagnosis of @entity401 had been made. Thus, we concluded that idiopathic @entity401 had gradually advanced preoperatively, and acute exacerbation was triggered by perioperative stress. The present case warned us that acute exacerbation of @entity401 could occur in a @entity1 with mild symptoms. Therefore, preoperative proper diagnosis is thought to be important as acute exacerbation of @entity401 is a highly morbid clinical event.
