Renal hypoplasia and dysplasia in an American miniature foal

Diagnostic imaging, including computed tomography, of a two-month-old foal with renal failure indicated that its right kidney was probably absent and that its left kidney was abnormal in shape. The foal was stabilised and rel eased, but three days later its clinical signs recurred. Postmortem examina tion revealed renal hypoplasia and dysplasia, the first reported case of th is condition in an American miniature horse.
