Presentation
Abdominal pain.
Patient Data
Treatment related changes in the right chest are partially imaged. Mild distal esophageal thickening. Relatively long-segment proximal small bowel - small bowel intussusception with upstream dilation of the bowel and stomach. Ill-defined lead point with mass-like thickening. Adjacent abnormal mesenteric lymph nodes. Changes related to distal small bowel resect
Case Discussion
Small bowel - small bowel intussusception due to melanoma metastasis, in this patient with a history of small bowel resection due to metastatic lesion. The thickening toward the lead point, adjacent enlarged lymph nodes, and supporting history help to increase diagnosis that this is not a transient finding (which would also typically be a lot shorter).
