The authors present a seventy-eight year old woman with an aneurysm of
the main pulmonary artery. Although a surgical approach is generally
considered life-saving by preventing rupture of the aneurysm, literatu
re is unclear about possible rupture in the specific situation of a pu
lmonary artery aneurysm without a causative cardiac lesion and/or pulm
onary hypertension. In fact, some reports suggest a conservative treat
ment for this specific entity. Therefore we did not operate on our pat
ient and she remains stable at 18 month follow-up.
