本文报道了５例（８只患眼）较为罕见的脉络膜骨瘤。着重讨论了本病的ＣＴ表现、诊断和鉴别诊断。结果表明：ＣＴ不仅可以显示脉络膜骨瘤的骨化以及无症状患者的微小钙化，有利于早期观察和治疗，而且还可以观察周围组织有无病变，帮助鉴别诊断。脉络膜骨瘤ＣＴ表现分为斑点形；短线（带）形；纺棰形；混合形。高分辩率ＭＲ加增强、用眼部表面线圈，可以发现骨瘤骨小梁中的骨髓信号，对诊断亦有帮助。
This article reports 5 cases (8 eyes) of the more rare choroidal osteoma. Focus on discussing the CT manifestations of this disease, diagnosis and differential diagnosis. The results show that CT can not only show the ossification of choroidal osteoma and microcalcification in asymptomatic patients, but also be helpful for the early observation and treatment. CT can be used to observe the presence or absence of surrounding tissues and help to differentiate the diagnosis. Choroidal osteoma CT findings were divided into spot-shaped; short-term (band); Spinning; mixed shape. High-resolution MR plus enhancement, with the eye surface coil, can be found in the bone marrow trabecular bone marrow signal, the diagnosis is also helpful.
