○ **Mycotic Aneurysms**

Mycotic aneurysms involving the pulmonary vasculature are less common and small number of cases have been reported in the literature [36]. Staphylococcus and streptococcus species are the most common organisms involved in developing these aneurysms, but it can also occur in the settings of mycobacterial or fungal infections. Clinical manifestations are usually related to the underlying endocarditis and manifestations specific to these mycotic aneurysms are rare except when rupture occurs which can lead to catastrophic hemoptysis.

Computed tomography scan is the most reliable for detection of these aneurysms. Due to the high mortality associated with rupture of these aneurysms, transcatheter embolization is recommended, although successful antibiotic therapy have been documented in those with small aneurysms that are stable [37].
