Objective:
To compare the MRI features of peliosis hepatis and hepatic metastases following chemotherapy for gastrointestinal adenocarcinoma with the aim to improve the differential diagnosis.
Methods:
The clinical data of 33 patients with gastrointestinal adenocarcinoma treated from June 2014 to December 2017 at Zhongshan Hospital of Fudan University were retrospectively analyzed. Of the 26 males and 7 females aged (56.0±9.8) years, there were 11 patients with peliosis hepatis and 22 patients with hepatic metastases following chemotherapy in these patients. All patients underwent contrast-enhanced abdominal MRI scans. The differences in the MRI features, including morphology, margin, signal intensity on plain scanning and enhancement patterns were compared statistically. The apparent diffusion coefficient (ADC) values of peliosis hepatis, hepatic metastases and adjacent hepatic parenchyma were measured in an ADC map.
Results:
In 14 lesions of the 11 patients with peliosis hepatis, 10 lesions were ill-defined and 4 lesions were well-defined. In 31 lesions of the 22 patients with hepatic metastases, 5 lesions were ill-defined and 26 lesions were well-defined. Significant differences existed between peliosis hepatis and hepatic metastases in the margin (
