The Clinical Value of Dynamic-Enhanced CT Scanning in Diagnosing Splenic Hemangiomas

Objective To investigate the dynamic-enhanced CT manifestations of splenic hemangiomas,and to discuss the diagnostic value of CT features. Methods A total of 13 cases with pathologically-confirmed splenic hemangiomas were enrolled in this study. Both plain and dynamic-enhanced CT scans were performed in all patients. The results were analyzed. Results A total of 16 lesions were detected in the 13 patients. On plain CT scan,the lesions presented as iso-density( n = 3) or low-density( n = 13) mass,round or oval in shape with sharp border,and no calcification was found in all lesions. Tri-phase contrast-enhanced CT scanning showed that the lesions were of hyper-density,and displayed various enhancement patterns in arterial phase,including complete homogeneous enhancement( n = 4),inhomogeneous enhancement( n = 2),lace-like edge enhancement( n = 3),ring-shaped enhancement( n = 1) and mild enhancement( n = 6). Of the13 patients,correct diagnosis was made in 12( 92. 3%). The disease was misdiagnosed as lymphoma in one patient.Conclusion Splenic hemangiomas have a variety of CT enhancement patterns. For CT diagnosis of atypical splenic hemangiomas,delayed scanning is particularly important. Iso-density enhancement of the lesion during delayed phase is characteristic manifestation of splenic hemangiomas.
