Abstract：Objective To investigate the CT performance of sclerosing angiomatoid nodular transformation (SANT) of the spleen. Methods Clinical and CT data of 11 patients with SANT which were confirmed by operation and pathology were retrospectively analyzed, and the related literatures were reviewed. The CT performance of SANT were analyzed and summarized. Results The 11 cases were all solitary (11/11) and with low density (11/11) by CT noncontrast enhanced scan. Calcification in the center of the lesion was scanned in 1 case (1/11). Among the 11 cases, 4 presented with with an unclear boundary (4/11), and 7 with a clear boundary (7/11). CT enhanced scan of 11 cases showed a trend of progressive and concentric enhancement (11/11). 4 cases presented with nodular enhancement (4/11), 7 cases with " Spoke Wheel Pattern" (7/11), 8 cases with false envelope (8/11), and 9 cases with "Star sign"(9/11). Conclusion CT manifestations of SANT has certain characteristics: progressive enhancement, " wheel syndrome" and "astral sign". And pseudocapsule appeared highly suggestive SANT.
