Abdominal paragangliomas are rare tumors that arise near the root of the inferior mesenteric artery, termed the organ of Zuckerkandl. The laparoscopic approach is technically demanding for abdominal paragangliomas and tumor handling is difficult. A 26-year-old woman presented with abdominal pain. Pelvic CT and MRI showed a round, well defined, 53 × 51-mm mass attached to the sacrum. The preoperative diagnosis was schwannoma arising from the retroperitoneum and laparoscopic tumor resection was performed. Intraoperatively, the tumor appearance was of a round, whitish mass in the retroperitoneum, with involvement of the inferior mesenteric artery, which was ligated and dissected. We used indocyanine green fluorescence imaging to assess colonic perfusion. The histological findings were consistent with paraganglioma. We performed complete resection of a paraganglioma arising from the organ of Zuckerkandl combined with resection of the inferior mesenteric artery. Indocyanine green fluorescence imaging helped confirm adequate blood flow and avoided resection of the colon.
