摘　　要：BACKGROUND Primary chondrosarcoma of the liver are extremely rare.Moreover,there are few reports focusing on typical clinical symptoms and imaging characteristics.Therefore,the diagnosis of chondrosarcoma of the liver remains a challenge.CASE SUMMARY A 59-year-old male was admitted due to a lesion occupying the right liver lobe that was found by physical examination.Magnetic resonance imaging showed a lobular mass with high T2 weighted image and low T1 weighted image with enhanced internal separation and edge in the right liver.He was diagnosed with liver cystadenoma by using magnetic resonance imaging.At 3 mo later,the magnetic resonance scan showed that the mass was enlarged.Laparoscopic liver tumor resection was performed with a pathological diagnosis of liver chondrosarcoma.Then he received a surgical resection for the recurrent lesion.However,intrahepatic and abdominal metastases were found again at 8 mo after the second operation.The patient then received conservative management and is now under follow-up.CONCLUSION Primary liver chondrosarcoma generally is presented as lobulated and heterogeneous density/signal,cystic,solid masses without calcification with enhanced edge,internal septa and solid part.The imaging features are closely related to pathology,which may be helpful for clinical diagnosis.
