  • Title: [The clinical significance of calcification in orbital computed tomography].
    Author: Pan Y, Song GX, He YJ.
    Journal: Zhonghua Yan Ke Za Zhi; 2004 Mar; 40(3):197-8. PubMed ID: 15307994.
    Abstract:
    OBJECTIVE: To study clinic significance of ocular and orbital diseases with computed tomographic (CT) scans. METHODS: 2181 ocular and orbital photos of computed tomographic scans were reviewed. The relevance with pathogenesis, diagnosis criteria and differential diagnosis of calcification was analyzed. RESULTS: Of 2181 CT scans, 129 showed calcified densities. 40 cases (31%) with retinoblastoma, and 3 cases (1%) with chorodal osteoma were revealed intraocular lesions containing calcium. The massive calcification was demonstrated in orbital diseases including 58 cases (45%) with vascular lesions, 19 (15%) cases with other orbital benign tumors and 9 cases (8%) with orbital malignant tumors. CONCLUSION: The calcification number, location and shape within lesions are of great value in the diagnosis of ocular and orbital diseases.
