ALTERACIONES SENILES EN EL CEREBRO DE LOS PERROS - ASPECTOS DE IMAGENOLÓGICOS
Palabras clave:
cerebro, envejecimiento, perro, resonancia magnética, tomografía computadorizadaResumen
Estudios relacionados con la verificación de las alteraciones seniles en el cerebro de los perros
se han tornado muy importantes debido a la creciente atención a la salud de los perros de edad
avanzada. La determinación de los hallazgos normales durante el proceso de envejecimiento
permite la identificación de alteraciones durante el mismo. En la condición normal de este
proceso, se puede identificar reducción volumétrica de varias regiones del cerebro asociado a
ensanchamiento de los surcos cerebrales; leve a moderada dilatación de los ventrículos
laterales; disminución en la altura del hipocampo y ensanchamiento de los cuernos
temporales. En pacientes de edad avanzada es posible observar reducción de la atenuación de
la sustancia blanca y gris, así como alteraciones de la intensidad en las imágenes cerebrales
utilizando la tomografía computarizada y la resonancia magnética, respectivamente. En esta
última modalidad de imagen se han descrito áreas hiperintensas en la secuencia T2 e
hipointensas en T1 en el cerebro de seres humanos y caninos, respectivamente. En estos
pacientes, ocurre un aumento de la frecuencia de estas lesiones con el envejecimiento.
