Hypoplastic Celiac Trunk With Aberrant Hepatic and Splenic Arteries: A Case Report.

Vascular anomalies of the celiac trunk and its branches are rare but carry significant diagnostic and surgical implications. We report a case of a 24-year-old male presenting with acute abdominal pain and vomiting. Contrast-enhanced CT revealed a hypoplastic celiac trunk with aberrant hepatic and splenic arteries arising from the superior mesenteric artery (SMA), a configuration distinct from the more commonly described replaced right hepatic artery. Associated findings included dilated duodenum and jejunum with wall thickening and mesenteric inflammation, likely reflecting altered mesenteric hemodynamics. The patient was managed conservatively for an acute abdomen with suspected transient vascular congestion. This rare vascular variant highlights the importance of CT angiography in identifying atypical anatomy, which is crucial for preventing misdiagnosis and guiding safe surgical or interventional procedures.
