There are no reports of cystic liver infection after liver transplantation. Herein, we report a rare case of cystic liver graft infection after living donor liver transplantation (LDLT). The patient was a 24-year-old man with primary sclerosing cholangitis who underwent right lobe graft LDLT. Preoperative abdominal computed tomography (CT) revealed a liver cyst at segment 8 of the donor liver. Biliary reconstruction was performed with hepaticojejunostomy. The postoperative course was uneventful until the patient developed a high fever and abdominal pain 15 months after LDLT. Abdominal contrast CT revealed abscess formation. Percutaneous drainage of the cyst was performed and purulent liquid was drained. The fever gradually subsided after treatment. On follow-up CT, the size of the infected liver cyst was decreased. Clinicians should be aware of the potential for cystic liver infection when using grafts with liver cysts, particularly when biliary reconstruction is performed with hepaticojejunostomy.
