Subclavian artery aneurysm: a rare cause of massive haemoptysis

Alireza Nathani et al. BMJ Case Rep. .

Abstract

A 35-year-old man was admitted to the intensive care unit with massive haemoptysis. CT of the chest revealed a necrotic right upper lobe mass. Angiography of his thoracic vasculature revealed a pseudoaneurysm in the right subclavian artery with active contrast extravasation. This anatomic deformity was stented and coiled with the assistance of interventional radiology. Bronchoscopy with lavage and brushings of the right upper lobe mass revealed fungal hyphae and positive galactomannan, supporting that the patient developed invasive pulmonary aspergillosis leading to a mycotic pseudoaneurysm of the right subclavian artery followed by massive haemoptysis.

Keywords: adult intensive care; pneumonia (respiratory medicine).
