CT and MRI manifestations of liver fluke granuloma

Objective To investigate the CT and MRI manifestations and clinical features of liver fluke granuloma. Methods A retrospective analysis was performed for the clinical and imaging data of 5 patients with pathologically confirmed liver fluke granuloma who were hospitalized in The First Affiliated Hospital of Guangxi Medical University from January 2010 to September 2015. Results Liver fluke granuloma had slightly low density on CT plain scan, as well as a slightly low signal on T1 weighted images and a slightly higher signal on T2 weighted images of MRI plain scan. Three-phase contrast-enhanced CT scan showed delayed enhancement with mild dilatation of the intrahepatic bile duct, and normal vessels ran through the lesion. Conclusion Liver fluke granuloma is a rare disease in clinical practice. A history of eating raw fish, delayed enhancement on three-phase contrast-enhanced CT scan, and normal vessels running through the lesion all contribute to the diagnosis of liver fluke granulomas.
