Abstract:
Objective To discuss the imaging features of parietal bones atrophy,and to improve the understanding of this disease. Methods Clinical and imaging data of 8 patients with parietal bones atrophy were analyzed retrospectively.Age ranged 66-90 years with median age 76 years.CT scans were performed in all cases,and CT enhanced examination in 1 case.MRI examination were performed in 3 cases,in which MRI enhanced examination in 2 cases.Imaging characteristics were analyzed along with a review of the current literature.Results Bilateral parietal sympathetic involvements were found in 4 cases,unilateral parietal involvement in 4 cases,in which the left parietal bone was found in 2 cases and the right side in other 2 cases.The lesions ranged from 2.4 cm to 7.1 cm.On CT and MRI images,the external table of the parietal bones showed symmetrical impression,the diploe revealed thinner and the inner table was intact,which presented"Step change".Two of these patients were followed up,in which 1 case become severe atrophy,and the other case was no significant change.Nothing was showed in the relative scalp and soft tissue.Conclusion According to different degrees of thinning of parietal bones,combined with specific age,symmetrical parietal bone impression should be considered.
