[edit] Discussion of Pulmonary artery aneurysm


  • In appropriate clinical settings, an aneurysm or pseudoaneurysm should be suspected in patients who present with hemoptysis or in whom chest radiography shows hilar enlargement or a new focal lung mass that has stable or increased size at subsequent radiographic examination.
  • Early diagnosis is crucial as the mortality rate for patients with a ruptured pulmonary artery aneurysm is 100%.

[edit] Imaging Findings for Pulmonary artery aneurysm

  • Helical CT is considered the noninvasive imaging modality of choice for the work-up of patients suspected of having pulmonary artery aneurysm, prior to therapeutic interventions (embolization or surgery).
  • Contrast-enhanced CT allows assessment of the presence, size, and location of the aneurysm; aneurysms appear as saccular or fusiform areas of dilatation, with homogeneous contrast material filling that occurs simultaneously with that in the pulmonary artery.
