Abstract: Objective To investigate the CT characteristics of skull chlesteatoma,and explore its diagnostic accuracy.Methods CT characteristics of 15 skull chlesteatomas confirmed by surgery and pathology were retrospectively analyzed.CT plain scan were performed in all the patients,while extra enhanced CT scan was done in 2 cases.Results On the CT images,all cases were solitary.14 cases originated from intradiploe,and one case from skull suture.Extensive destruction of the skull with hard margin was found in 15 patients.7 cases presented crater-form deossificatio.11 cases demonstrated inhomogeneous density in which 6 cases showed calcification.The fat-like density was noticed mainly in one case,the water-like density mainly in 2 cases,the iso-density mainly in 2 cases,and homogeneous density in 4 cases.MPR and VR images could display the shape and scope of destruction.2 cases showed mild enhancement on contrast CT.Conclusion CT scanning of skull chlesteatomas has some features,CT combining with post-processing techniques are very effective in the diagnosis of skull chlesteatomas.
