Abstract：Objective To exPlore the value of CT diagnosis and differential diagnosis of sPlenic tumors. Methods 30 Patients with sPlenic tumors(13 were benign and 17 were malignant)were examined by CT Plain and enhanced scanning. 18 Patients were confirmed by oPeration and Pathology,16 were diagnosed by tyPical signs and definite histo-ry. Results Single or multiPle low density nodular lesions were manifested in benign tumors,and 1 hemangioma was isodense. Punctate or flake calcifications could be shown in hemangioma and lymPhangioma. Homogeneous and marked enhancement occurred in hemangiomas at delayedPhase,mild enhancement occurred in lymPhangioma in the interval, and no enhancement occurred in sPlenic cyst. Calcification of sPlenic hamartoma and adiPose tissue mass were charac-teristic manifestations. Malignant tumors of sPleen were mostly large of uneven density with heterogeneous density. SPlenomegaly and multiPle low density nodular lesions were manifested in sPlenic lymPhoma with unobvious enhance-ment. Conclusion CT is the main examination method in the diagnosis of sPlenic neoPlasmas,which can make etio-logical diagnosis combined with clinical history and B - ultrasound examination.
