Multiple mycotic aneurysms of the pulmonary arteries resolving with conservative management: multislice CT examination findings.

Mycotic pulmonary artery aneurysms are rare but potentially fatal complications of infective endocarditis. Three mycotic aneurysms developed in a 22-year-old female patient who had a history of intravenous drug use. She suffered from Staphylococcus aureus pneumonia and infective endocarditis. The patient was managed conservatively with antibiotics. She did not have hemoptysis during a prolonged hospital stay. Several multislice computed tomography examinations were performed to follow these aneurysms over a period of 19 months. The 2 smaller aneurysms had resolved by 9 weeks postdevelopment. The largest aneurysm was stable at 9 weeks and was smaller at 19 months, but it had not yet completely resolved. The literature on this rare condition was reviewed and its prognosis and management were discussed.
