Mielopatia comprensiva por extrusión de disco calcificado a nivel de L1 -L2, en dirección dorsolateral izquierda con estenosis de hasta 50% del canal vertebral en camino Jack Russell de 6 años.

Abstract

Intervertebral disc disease in this case leads to spinal cord compression with symptoms related to mobility problems in the hind limbs. Progressive muscle weakness is reported that could progress with paraparesis and moderate ataxia until presenting total loss of movement in hind limbs. Difficulty going up and down stairs, poor positioning of the pelvic limbs represented by their dragging and lack of proprioception. The pain gradually increases, but urinary function and fecal control remain intact up to this point. It belongs to the chondrodystrophic breeds, this refers to a genetic modification to shorten their long bones. The diagnosis by neurological characteristics of progressive course, the race, age and the data obtained by the physical examination and neurological examination of the patient where a neurolocation must be reached, imaging techniques, response to corticosteroids and, if possible, lymphoproliferation results. X-rays revealed narrowing of the intervertebral space and foci of mineralized disc material. Magnetic resonance imaging allowed us to determine compressive myelopathy due to extrusion of a calcified disc at the level of L1-L2, in a left dorsolateral direction with stenosis of up to 50% of the vertebral canal.
