Patient Data

Age: 35 years
Gender: Male
CT

The left upper lobe shows patchy ground-glass opacities with numerous tiny and randomly distributed pulmonary nodules. Scattered tree in bud opacities and mild bronchiectatic changes also noticed. There is a small cavitary lesion with an avidly enhancing solid component seen in the post-contrast study indicating a tuberculous cavity and a related aneurysm of the subsegmental pulmonary artery (Rasmussen aneurysm).

Case Discussion

It is important to put in mind the possibility of Rasmussen aneurysm when tuberculous cavity shows solid components even in a small cavity like in this case. An additional post-contrast study was requested that revealed this significant finding.
