COMPUTED-TOMOGRAPHY OF CHOLESTERINIC GRANULOMAS IN THE CHOROID-PLEXUSOF HORSES

Cholesterinic granulomas are tumor-like masses in the choroid plexuses of horses. This report describes the computed tomographic findings in four horses with cholesterinic granulomas, including the clinical and the pathologic features. All four horses had bilateral cholesterinic granulomas in the lateral ventricles. Computed tomographic images clea rly delineated the masses, the opacity of the granulomas, and the enha ncement pattern after intravenous bolus injection of contrast medium; these factors varied considerably, Additional CT findings were symmetr ic or asymmetric widening of the lateral ventricles.
