RESUMO
Objective To evaluate CT findings and the common causes of calcification of the eyeball wall.Methods CT manifestations of 26 cases of calcification of the eyeball wall were reviewed.3 cases were confirmed by surgery and pathology.Etiological diagnosis was made in 23 cases on the basis of detailed history,ophthalmic examination,clinical laboratory and follow-up results.Results Of the 26 patients with calcification of the eyeball wall,19 occurred in unilateral eye,7 occurred in bilateral eyes.The common causes of calcification of the eyeball wall included choroidal osteoma(n= 7),sclerochoroidal calcification(n= 5),subconjunctival lipoma with calcification(n= 4),optic diskdrusen(n=3),long-standing retinal detachment(n=3),recurrent traumatic endophthalmitis(n=2),chronic uveitis(n=1)and postkeratoplasty (n=1).The calcified lesions located in the back of equator of eyeball were showed in 17 patients(66%),in the front of equator in 5 patients(19%),both in the front and back of equator were seen in 4 patients(15%)with multiple lesions.On CT,calcified lesions of the eyeball wall mainly demonstrated some punctiformed,stippled,flat,peltate and irregular high density lesions,and 4 cases with ocular atrophy.Conclusion Most diseases that result in calcification of the eyeball wall have typical location and lesion shape.CT scan is valuable for finding the etiological factors and guiding the clinical treatment.
