Histopathology showed: hemorrhages in adrenal cortex, capsule thickening and atrophy cortical with coagulation necrosis of zona glomerulosa, coagulation necrosis focal zona fasciculata, only congestion of the zona reticularis.

En el examen clínico el caballo presentaba agotamiento, depresión, letargo y anorexia. Luego de iniciar el tratamiento el caballo murió. En la necropsia se evidenciaron múltiples hemorragias en la corteza adrenal y zona cortical renal con necrosis papilar y necrosis tubular aguda. La histopatología mostró: hemorragias en la corteza adrenal, engrosamiento y atrofia de la cápsula cortical con necrosis por coagulación de la zona glomerulosa, necrosis por coagulación focal de la zona fasciculata y congestión de la zona reticularis. En conclusión, reportamos un caso de síndrome de insuficiencia adrenocortical en un caballo de resistencia con rápido desarrollo de signos clínicos, sin respuesta a tratamiento de emergencia, confirmado con resultados de laboratorio, necropsia e histopatología.]]></p></abstract>
