Chordomas are known as rare primary malign tumours that have formed from primitive notochord remains. Sacral chordomas grow slowly but locally and aggressively. Chordomas are locally invasive and have low tendency to metastasis and have a poor prognosis in long-term follow-up. Metastasis may be seen in a rate of 5–40 % of the chordomas. Metastasis of chordomas is common in liver, lung, lymph nodes, peritoneum, and brain. The treatment approaches, including surgery, have been discussed in the literature before. Susceptibility to radiotherapy and chemotherapy is controversial in these tumours. The success of surgical treatment affects survival directly. In this report, wewill report a sacral chordoma case inwhich an intraperitoneal distantmetastasis occurred and discuss the surgical approach. 1. Objective Chordomas are low-grade, rare, and primarilymalign tumors that grow slowly. They rarely have distant metastasis, but instead more locally recurrent tumors grow from primitive notochordal cell remnants. The yearly incidence is estimated at 5/1,000,000; 50–60 % of cases are seen in the sacrum, 25
