Pulmonary hemorrhagic lesions and coronary artery aneurysm accompanied by thrombosis.

This document presents a case report of a 74-year-old male patient admitted with three days of persistent chest pain accompanied by hemoptysis. Diagnostic imaging, including chest CT and coronary CT angiography, revealed pulmonary hemorrhagic lesions appearing as ground-glass opacities, predominantly located in the right lung, as well as a coronary artery aneurysm with surrounding thrombus in the circumflex artery. The case underscores the potential interplay between coronary vascular anomalies and pulmonary complications, emphasizing the value of advanced imaging techniques in diagnosis.
