Pulmonary artery aneurysms are rare and infrequently diagnosed. Various origins have been described, like congenital causes, acquired causes, and idiopathic. Among all of them idiopathic pulmonary artery aneurysm is the rarest variety.
Clinical manifestations remain nonspecific; include dyspnoea, chest pain, hoarseness, palpitation. If bronchial compression is there, it may cause cough, breathlessness, cyanosis, syncope attacks and rarely large aneurysm can cause haemoptysis.
There is no clear guideline for the treatment for pulmonary artery aneurysm. Conservative treatment is the main stay for this disease when it is not related with any congenital anomalies and normal pulmonary artery pressure. In case of disabling symptoms, operative management is the cornerstone for this entity.
