An Uncommon Culprit in SMA Syndrome: Navigating Through Duodenal Adenocarcinoma-Induced Obstruction

Abstract

Superior Mesenteric Artery (SMA) Syndrome is an infrequent vascular compression disorder, characterized predominantly by the extrinsic obstruction of the third part of the duodenum by the SMA, leading to a spectrum of gastrointestinal symptoms. While most commonly associated with rapid weight loss and anatomical variations, its occurrence in the context of adjacent malignancies remains exceedingly rare and clinically significant.

Here I detail a compelling case of a 49-year-old male, initially presenting with nonspecific symptoms of intermittent abdominal pain and vomiting. The diagnostic journey, propelled by computed tomography (CT) and subsequent investigations, unveiled an underlying duodenal adenocarcinoma exerting extrinsic pressure, precipitating SMA syndrome. This report delineates the diagnostic nuances encountered in distinguishing SMA syndrome's etiology, emphasizing the adenocarcinoma's role in the syndrome's manifestation. The therapeutic strategy entailed a multidisciplinary approach, culminating in surgical intervention, which not only relieved the vascular compression but also addressed the malignant etiology.

This case underscores the imperative for heightened clinical vigilance and comprehensive diagnostic exploration in patients presenting with gastrointestinal obstructions, where SMA syndrome may masquerade as a benign condition. The convergence of SMA syndrome and duodenal adenocarcinoma illustrates a rare clinical entity that necessitates an astute assessment to unveil its malignant underpinnings.
