MIGRATING PULMONARY ANEURYSM IN BEHÇET VASCULITIS

Behçet's disease (BD), also called Behçet's syndrome, is a rare multisystemic vasculitis that causes blood vessel inflammation throughout the body. It may affect multiple organs and less frequently involves the central nervous system, potentially resulting in thrombotic events and aneurysm formation, the most notably pulmonary artery aneurysms (PAA). We present a case of a 44-years-old female who sought medical attention due to prolonged hemoptysis combined with chest pain. Ascribed to these symptoms, initial computer tomography (CT) (native and arterial phases) revealed an oval mass in the left hilum. Subsequent CT angiography demonstrated an aneurysm of the left interlobar artery compressing the segmental bronchus with associated thrombus formation. The patient refused surgical intervention. One year later, a follow-up CT angiography showed the resolution of the initial aneurysm but revealed a new aneurysm in the right main pulmonary artery. This case highlights the rare migratory nature of pulmonary aneurysms in Behçet vasculitis, underscoring the need for early diagnosis, imaging follow-up and interdisciplinary management
