Abstract：
OBJECTIVE: To describe MRI features of multiple Focal Nodular Hyperplasia (FNHs).
METHODS: 40 consecutive subjects (37 females, mean age, 38.8years) were included. All studies were independently reviewed. This was an observational study to define the radiological features of multifocal FNH.
RESULTS: 130 lesions were evaluated. The majority (88.5%), were peripheral in location. 92.3% lesions were lobulated. Marked enhancement was present in 94.6% lesions. In the portal venous and delayed phase, 46.2% and 47.7% lesions were mildly hyperintense. Central scar was present in 77% lesions.
CONCLUSIONS: Distinctive features included predominant subcapsular location and mild hyperintensity in the delayed phase, seen in nearly 50% of FNHs.
