Introduction:
Carcinosarcomas of the gallbladder are rare tumors that are characterized by malignant epithelial and mesenchymal components, and preoperative diagnosis of carcinosarcoma of the gallbladder remains difficult.
Case Report:
We recently encountered a case of carcinosarcoma of the gallbladder with osteoid and chondroid differentiation, manifesting as cholangitis due to hemobilia.
Conclusion:
Preoperative computed tomography and magnetic resonance imaging indicated the cause of cholangitis and provided qualitative information regarding the two components of the tumor.
