CT diagnosis of primary orbital lipid prolapse / 中国医师进修杂志

ABSTRACT

Objective To investigate the CT findings of primary orbital lipid prolapse. Methods The CT data of 13 patients with primary orbital lipid prolapse in Jiaxing Traditional Chinese Medicine Hospital Affiliated to Zhejiang Chinese Medical University from January 2012 to June 2018 were retrospectively analyzed. Results In all of the 13 cases of primary orbital lipid prolapse, there were 12 cases of bilateral orbital lipid prolapse and 1 case of unilateral orbital lipid prolapse. The CT images showed that the fat density masses in the posterior orbital septum were herniated from the outer quadrant of the orbit. The tumor was crescent shaped and connected with the orbital adipose tissue. The mass and the orbital adipose tissue were natural and homogeneous. Conclusions CT has distinctive imaging findings in the diagnosis of primary orbital lipid prolapse, and it is helpful for the diagnosis and differential diagnosis of this disease.
