Abstract:
Objective To evaluate the CT value in diagnosis and differential diagnosis of splenic tumors.Methods 52 cases of splenic tumors were examined by plain and contrast-enhanced CT scan.27 cases of splenic tumors were confirmed by operation and pathology,25 cases were definited by clinical history and having typical imaging signs.Results There were 18 benign and 34 malignant tumors.Most of benign splenic tumors appeared as single or multiple low dense nodus with different size,one hemangioma was isodense.Calcifications could be showed in splenic hemangioma and lymphangioma.Homogeneous and marked enhancement occurred in hemangiomas at delayed-phase,no or slightly enhanced in the septum of splenic lymphangiomas,and the cysts had no enhanced.The malignant tumors of spleen were bigger in size mostly with unhomogeneous density,and unhomogeneous enhancement could be seen at contrast-enhanced CT scan.Uneven enlargement of spleen was commonly seen in patients of splenic lymphoma and the lesions were multiple in a most of cases,and had not enhancement obviously.Conclusion Splenic tumors can be diagnosed correctly in most patients based on the features of plain and contrast-enhanced CT in combination with clinical history and the other examinations.
