Large ciliary body melanocytoma with pseudocysts: a case report

BACKGROUND: To describe the correlation between standardized A-scan echography and histopathology in a ciliary body melanocytoma. CASE PRESENTATION: We present a case of a large ciliary body melanocytoma with significant growth, vision loss, and elevated intraocular pressure that was diagnosed clinically as a melanoma, but the standardized A-scan findings correlated to the histopathological description of a melanocytoma with multiple pseudocysts. CONCLUSIONS: The reflectivity of this melanocytoma by standardized A-scan was consistent with multiple pseudocysts on pathological evaluation. This echographic pattern guided the differential diagnosis. Standardized A-scan is an important diagnostic tool in the differentiation of ciliary body melanocytomas from melanomas.
