A 28-years old female presented with complaints of palpitations and mild retrosternal chest pain. CXR showed a prominent Pulmonary artery. A TTE study revealed a huge main pulmonary artery whereas the branches were of normal size. CT angio revealed aneurysmal main Pulmonary artery and normal sized branches. No concomitant etiology was noted, hence labelled as “idiopathic pulmonary artery aneurysm”.
A 28-year-old female presented with retrosternal chest pain and palpitations for the last six months. Multiple systolic clicks and murmur III/VI heard in the pulmonary area. ECG was unremarkable. Chest X-Ray showed no cardiomegaly and a prominent pulmonary artery. Transthoracic echocardiography showed aneurysmally dilated main pulmonary artery (size: 5.7cm). Pulmonary valve was thickened with mild regurgitation. CT angiogram demonstrated dilated main pulmonary artery (axial dimension: 5.8cm) with normal-sized branches (Figure1). Immunological workup was negative. She was advised surgical intervention which she agreed to pursue soon at a tertiary care hospital near her hometown.
