Synopsis

Keywords: Liver, CancerProblem: To illustrate the MRI manifestations of spontaneous intratumoral coagulative necrosis (iCN) in hepatocellular carcinoma (HCC) and its value in predicting postoperative early recurrence. Methods: 263 patients with HCC confirmed by surgical pathology were enrolled. The qualitative assessments of MRI features were performed. Results: The iCN in HCC was characterized by a similar appearance to the tumor on pre-contrast MRI but with non-enhancement on post-contrast MRI. Presence of iCN on MRI was associated with early tumor recurrence. Conclusions: Presence of iCN on MRI is associated with early tumor recurrence and might assist to guide clinical treatment.
