title: Ultrasonic findings in intraocular retinoblastoma and correlation with histopathologic diagnosis.
abstract: A and B-scan ultrasonographic records of 132 eyes of 126 patients with suspected retinoblastoma were evaluated retrospectively. Six patients had bilateral lesions. The results were compared with the histopathologic diagnoses obtained after enucleation in 129 cases and with the indirect ophthalmoscopic examination in 3 bilateral cases. Ultrasonographic diagnosis was correct in 115 cases (87.12%), false-negative in 12 cases (9.09%) and false-positive in 5 cases (3.79%). Echographic tumor typing was made in 88 cases and the mixed tumor type was the most frequent with 74 cases (84.09%). Cystic, solid and diffuse infiltrating types were the other echographic diagnoses. Our experience confirms the accuracy of ultrasonography in the diagnosis of retinoblastoma.
