[An AV aneurysm of a branch of the pulmonary artery associated with a pulmonary tumorlet]. / A-V aneuryzma vetve plicní tepny s plicním tumorletem.

The authors present a rare case of a relatively large A-V aneurysm of the branch of the pulmonary artery in the right upper pulmonary lobe. Successful and technically easy surgical treatment was preceded by a serious dilemma whether to select in a high risk patient another (less invasive) therapeutic method or even conservative treatment. The surgical finding and smooth postoperative course confirmed that the indication of surgery was correct. As a further pathological finding in the resected portion a pulmonary tumourlet was detected. The combination of the two rare findings is an extreme rarity.
