A 49-year-old male presented to our hospital with a liver tumor. CT revealed a slightly enhanced liver tumor of 30 mm in diameter in segment 6. The patient had a history of surgery for ameloblastoma 24 years ago and for metastatic lung tumors 4 years ago. Thus, laparoscopic partial liver resection was performed based on medical guidelines. Pathologically, the tumor was diagnosed as metastatic ameloblastoma. This case serves as an important reminder to consider metastatic ameloblastoma in an investigation of possible causes of a liver tumor after treatment for ameloblastoma.
A 49-year-old female with severe jaundice and liver dysfunction was transported to our hospital. Computed tomography revealed a contracted liver and massive ascites. The patient had undergone living-donor liver transplantation. On day 16 post surgery, the liver biopsy was performed to check for acute transplant rejection reaction. As a complication, the patient had intra-abdominal bleeding with shock vital signs; therefore, underwent interventional radiology (IVR) procedures. On day 155 post surgery, she had elevated alanine aminotransferase levels and portal vein regurgitation visible on ultrasonography. Hepatic arteriography showed an intrahepatic arterioportal (AP) shunt near the previous coil embolization. The patient underwent IVR again. This case serves as a reminder to consider AP shunt during differential diagnosis in patients with postoperative liver damage after the liver biopsy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
