Methods: During a recent 3-year period, 492 patients with hematemesis or melena (n=445) and septic shock (n=47) in liver cirrhosis visited our hospital. After applying the exclusion criteria, 136 patients with active variceal bleeding and 29 patients with septic shock were finally included in the study. We diagnosed multiple infarcted regenerative nodules based on the findings of the first follow-up (within 30days) CT after events. We evaluated the shape, number, size, margin, location, and distribution of the infarcted regenerative nodules. Results: Thirty-four patients were diagnosed with multiple infarcted regenerative nodules (20.6% [34/165]): 29 among 136 patients with variceal bleeding (21.3% [29/136]) and 5 among 29 patients with septic shock (17.2% [5/29]). Most of the infarcted regenerative nodules were round in shape, more than ten in number (79.4%), measured 1cm or less (76.3%), had well-defined margins (61.8%), were present in the periphery (67.6%), and had a clustered distribution (67.6%). Almost all of the infarcted regenerative nodules disappeared on the second follow-up CT (88.9% [16/18]). Conclusions: In cirrhotic patients, multiple infarcted regenerative nodules were not rare (they were found in about one-fifth of the patients) on the first follow-up CT after variceal bleeding or septic shock. Majority of the infarcted regenerative nodules were more than ten in number, measured 1cm or less, were located in the periphery, and had a clustered distribution.
