Incidental saccular aneurysm of the celiac trunk: A rare cause of abdominal pain

Celiac artery aneurysms (CAAs) are rare vascular anomalies, often discovered incidentally or during the evaluation of non-specific abdominal symptoms. Despite their rarity, they are clinically significant due to the risk of rupture, which can be life-threatening. We report the case of a 58-year-old woman who presented with progressive abdominal pain. Contrast-enhanced computed tomography (CT) of the abdomen revealed a well-defined saccular aneurysm involving the celiac trunk. The aneurysm demonstrated contrast opacification and was clearly delineated from adjacent structures. No signs of rupture or surrounding inflammation were identified. This case illustrates the key role of cross-sectional imaging—particularly CT angiography—in the detection, characterization, and assessment of visceral artery aneurysms. It also reinforces the need for radiologists and clinicians to include vascular etiologies in the differential diagnosis of abdominal pain, especially in patients without clear gastrointestinal or gynecologic causes.
