Metastatic small intestinal neuroendocrine tumor presented with partial intestinal obstruction in Saudi Arabia: a case report.

Abstract

Well-differentiated neuroendocrine tumors (NETs) of the ileocecal region are rare but increasingly recognized gastrointestinal neoplasms. They often present vague symptoms, delaying diagnosis. Despite slow growth, these tumors can metastasize to the liver and bone, complicating management. Despite their indolent nature, these tumors can metastasize to the liver and bone, complicating treatment. We report a case of a 54-year-old woman with a one-year history of vague abdominal symptoms that worsened over the last 2 months. Contrast-enhanced computed tomography imaging revealed a mesenteric lesion leading to partial intestinal obstruction. Further imaging revealed liver and spine metastases. Colonoscopy confirmed an obstructing ileocecal mass, and biopsy identified a Grade 1 well-differentiated NET. The patient underwent laparoscopic right hemicolectomy with ileocolic anastomosis for symptom relief, followed by octreotide therapy. This case highlights the diagnostic and therapeutic challenges of metastatic ileocecal NETs and emphasizes the importance of a multidisciplinary approach for effective treatment and long-term stability.
