Abstract
Gastroduodenal artery (GDA) aneurysms are rare vascular anomalies that can present with nonspecific symptoms, making diagnosis challenging. We report a case of a 26-year-old male presenting with abdominal distension, initially suspected to have a duodenal submucosal tumor. Advanced imaging techniques, including endoscopic ultrasonography (EUS) and computed tomography angiography (CTA), revealed a GDA aneurysm compressing the duodenal bulb. The patient was managed conservatively with regular follow-up, remaining asymptomatic over six months. This case underscores the importance of considering vascular anomalies in differential diagnoses of submucosal tumors and highlights the role of multimodal imaging in accurate diagnosis.
期刊介绍：
The mission of Clinical Imaging is to publish, in a timely manner, the very best radiology research from the United States and around the world with special attention to the impact of medical imaging on patient care. The journal''s publications cover all imaging modalities, radiology issues related to patients, policy and practice improvements, and clinically-oriented imaging physics and informatics. The journal is a valuable resource for practicing radiologists, radiologists-in-training and other clinicians with an interest in imaging. Papers are carefully peer-reviewed and selected by our experienced subject editors who are leading experts spanning the range of imaging sub-specialties, which include:
-Body Imaging-
Breast Imaging-
Cardiothoracic Imaging-
Imaging Physics and Informatics-
Molecular Imaging and Nuclear Medicine-
Musculoskeletal and Emergency Imaging-
Neuroradiology-
Practice, Policy & Education-
Pediatric Imaging-
Vascular and Interventional Radiology
