A Pulmonary Artery Pseudoaneurysm from a Locally Advanced Lung Cancer: A Case Report

Francis M Patafio

Abstract


Background: Pseudoaneurysms or false arterial aneurysms are infrequent complications that result from direct injury to the vascular wall leading to a single-layer hematoma. The formation of a pulmonary artery pseudoaneurysm secondary to an adjacent lung neoplasm is a rare occurrence.

Presentation of Case: We report a patient who developed a pseudoaneurysm of his left pulmonary artery from an infiltrating squamous cell carcinoma of the lung.

Conclusion: Despite the relative infrequency, the presence of a pulmonary pseudoaneurysm secondary to a lung cancer continues to have a high mortality. The aneurysm was managed with an endovascular stent with the goal of hemorrhage control. Unfortunately, the presence of the pseudoaneurysm in the context of his rapidly growing squamous cell carcinoma made the patient no longer a candidate for curative surgery, chemotherapy or radiation. After a long discussion on the patient’s wishes and goals of care, he decided for palliative care measures. He was sent home with home oxygen and community supports in order to spend the remaining days with his family.
