Abstract
Background: Renal cell carcinoma (RCC) is the most common primary malignancy of the kidney and is known for its unpredictable metastatic behavior. Although it commonly spreads to the lungs, bones, liver, and brain, metastasis to the small intestine is extremely rare. Case Presentation: We report the case of a 47-year-old male with a known history of metastatic RCC who presented with symptoms of intestinal obstruction. Contrast-enhanced computed tomography (CECT) of the abdomen revealed dilatation and wall thickening of the distal jejunum along with an exophytic hypodense lesion in the upper pole of the right kidney. Due to persistent symptoms, the patient underwent diagnostic laparoscopy with resection and anastomosis of the obstructed proximal ileal segment. Histopathological examination of the resected bowel segment confirmed metastasis from RCC. The postoperative period was uneventful, and the patient was started on adjuvant systemic therapy with immunotherapy. Conclusion: Small bowel metastasis from RCC is rare and may present with intestinal obstruction. This case highlights the importance of considering metastatic disease in patients with a history of RCC presenting with gastrointestinal symptoms, as early recognition and appropriate management are essential for optimal patient care.
