BACKGROUND: The usefulness of ultrasound-guided needle aspiration for @entity75 has been reported. However, no reports have evaluated its usefulness and safety in @entity1 with respiratory comorbidities such as @entity1030 ( @entity1030 ) and @entity401 ( @entity401 ), which can increase the risk of @entity4499 . In this study, we evaluated the influence of @entity1576 ( @entity1576 ) on the usefulness and safety of ultrasound-guided needle aspiration for @entity75 . METHODS: Between January 2000 and September 2011, we examined 144 @entity1 with intrapulmonary @entity75 . We retrospectively reviewed clinical data, including lesion size on thoracic computed tomography (CT), ultrasound findings, pathological findings obtained by ultrasound-guided needle aspiration, final diagnosis, and complications. RESULTS: A positive definitive diagnosis was obtained in 74.3% of all 144 @entity1 ; 84.7% @entity1 with @entity5 , including @entity2 ; and 26.9% @entity1 with benign diseases. Of the 144 @entity1 , 64 belonged to the @entity1509 group and 80 to the non- @entity1509 group. The former included 31 @entity1 with @entity1030 , six with emphysematous changes on thoracic CT, 17 with @entity401 , and 10 with other diseases. The positive rate of diagnosis for @entity5 was 84.7% in the @entity1509 group, which was the same as that in the non- @entity1509 group. With regard to complications related to ultrasound-guided aspiration, there were only two cases of pneumothorax in the @entity1509 group and one in the non- @entity1509 group. CONCLUSION: Ultrasound-guided aspiration is safe and useful for @entity75 , particularly malignant lesions, even in @entity1 with respiratory comorbidities such as @entity1030 and @entity401 .
