Objective To investigate the CT and MRI manifestations in splenic tumors, and improve the diagnostic accuracy rate of benign and malignant splenic tumor. Materials and Methods The CT and MRI scan data of 30 cases of splenic tumors with surgicalpathological proved splenic tumor were analyzed retrospectively. Results A total of 13 cases were benign tumor, 17 cases were malignant tumor. Splenic cavernous hemangioma, spenic cyst and splenic abscess were most common benign tumor in the spleen; splenic cavernous hemangioma showed multiple cystic lesions or solid lesion, and has local prominency in inner margin of spleen, and enhanced most depply. The typical cavernous hemangioma showed "lump bulb" sign on MR imaging. Spenic cyst were cystic lesions and mostly occured after injury, has no enhancement. Splenic lymphoma and metastatic tumor were the most common splenic malignant tumor. Splenomegaly, multiple nodular lesions or isolated inhomogeneous lesion could be seen in splenic lymphoma patients, and had inhomogeneous enhancement after enhanced. Splenic metastatic tumor were rare, showed multiple lesions in the spleen, and mostly secondary to the hematogenous spread of malignant tumor. Conclusion Serious analyze the CT and MRI manifestations in splenic tumors helps to improve the diagnostic accuracy rate of benign and malignant splenic tumor.
