Jejunal adenocarcinoma (JA) is both a rare type of gastrointestinal malignancy and an uncommon cause of small bowel obstruction (SBO). It typically presents with vague symptoms, such as abdominal pain, nausea, vomiting, and, in some cases, weight loss. Due to this vague presentation as well as lack of definitive imaging techniques, diagnosis tends to be delayed and patients typically present at later stages. We present a case of a patient who presented with acute onset abdominal pain. Imaging revealed the presence of an SBO with the presence of a suspicious small bowel stricture. He eventually underwent upper endoscopy to find the mass, with subsequent biopsy indicating JA. We hope to bring greater awareness to jejunal carcinoma as a potent cause of SBO in adults.
