This study presents a case of lymphocytic ganglioneuritis in a dog secondary to intervertebral disc extrusion that mimicked a peripheral nerve sheath tumour on magnetic resonance imaging. A four‐year‐old spayed female dachshund with lumbar pain was imaged via magnetic resonance. A tubular, space‐occupying, contrast‐enhancing lesion was noted in the right intervertebral foramen at L6 to L7 . This was presumed to represent focal enlargement of the right sixth lumbar spinal nerve. A right‐sided haemilaminectomy was performed at L6 to L7 and material that grossly resembled extruded nucleus pulposus was removed. The right L6 dorsal root ganglion, dorsal nerve root and proximal spinal nerve were severely enlarged and a partial thickness biopsy was collected from the dorsal root ganglion. Results of histopathological examination of the submitted tissue samples were consistent with extruded disc material and lymphocytic ganglioneuritis. To the author's knowledge, this is the first published report of lymphocytic ganglioneuritis secondary to intervertebral disc disease in a dog.
