Abstract

PURPOSE:

To describe the results of three-dimensional ultrasonography used to evaluate extrascleral extension of a choroidal melanoma.

METHODS:

Case report. The three-dimensional ultrasound system uses a 10-MHz B-mode transducer combined with a motorized rotating holder. The system acquires 180 sequential images that are stored and processed to create a three-dimensional block of the region of interest.

RESULTS:

Unique coronal and oblique perspectives were obtained from interactive manipulation of the three-dimensional reconstruction. Examination of the three-dimensional image allowed us to detect the transscleral uveal-orbital connection. Extrascleral melanomatous extension was confirmed on histopathologic examination.

CONCLUSION:

Three-dimensional ultrasonography is a promising imaging technique for evaluating melanomatous extrascleral extension.
