CT findings and differential diagnosis of benign tumors of spleen / 中国医学影像技术

ABSTRACT

Objective: To explore CT manifestations of 4 kinds of benign tumors of spleen and the key points of differential diagnosis. Methods CT findings of 4 kinds of benign tumors of spleen were analyzed retrospectively, including 18 cases of hemangioma, 3 cases of lymphangioma, 19 cases of hemolymphangioma and 1 case of harmatoma. CT characteristics of the above 4 kinds of benign tumors of spleen were observed. Results All hemangiomas were solid lesions, including single lesion in 11 cases, multiple lesions in 7 cases of spleen; 16 cases were with typical enhancement pattern. Lymphangioma was cystic lesion without enhancement. Hemolymphangioma could be solid, cystic, solid-cystic or mixed lesions. Most of the hemolymphangiomas were multiple (n=15) and solid (n=9) lesions, mild enhancement in the solid component and without enhancement in the cystic component. The appearance of harmatoma was a hypodense tumor with enhancement pattern similar to hemangioma. Conclusion All 4 kinds of benign tumors of spleen have certain CT characteristics, which are helpful to the diagnosis and differential diagnosis.
