Findings reveal a large lower lobe cavity with a well defined spherical lesion within the cavity, that intesely enhances on contrast administration.
Diagnosis
Rassmusen Aneursym in a chronic healed tuberculous cavity
Discussion
Rassmusen is caused by weakening of the pulmonary artery wall from adjacent cavitary tuberculosis, while mycotic aneurysm can occue in underlying fungal setting, and is common in IV drug users
Bronchial Artery Embolization (BAE) can be considered in Rassmusen aneurysms who bleed and fulfill criteria for BAE?
