Diagnostic value of CT in the masses of Scalp

Objective: To discuss the diagnostic value of CT in the masses of scalp.Methods: CT,clinical characteristics and histological findings of 128 lesions from 124 patients were analyzed retrospectively,including clinical symptoms,age of onset,sex,position of lesion,density of lesion,margin,and adjacent destruction of bones.Results: One hundred and twenty-four patients were included,92 males and 32 females.There were 120 cases with singe scalp mass,and 4 cases with multiple scalps masses.120 cases (93.7%)showed as benign masses,and 8(6.3%)as malignant masses.According to the tissue origin,the masses may originate from the scalp soft tissue or the skull.Lipoma(44/128),epidermoid cyst(19/128) and trichilemmal cystst(17/128)are consided as the most common pathological type.Conclusions: The position,morphology,density of mass and adjacent destruction of bone could be well indicated by CT,and this may produce an effective impact on diagnosis,CT scanning is the important assistant to clinicls.
