Plain-English summary
A 9-year-old dog showed signs of facial weakness and difficulty eating due to a condition called bilateral trigeminal neuropathy, which affects the nerves responsible for sensation in the face. After testing, the vet found that the dog had multicentric lymphoma, a type of cancer that was affecting the nervous system. The diagnosis was confirmed through a spinal fluid test and muscle activity tests. Unfortunately, the cancer had invaded the nerves, leading to the symptoms. Treatment options would typically include chemotherapy, but the specific outcome for this dog isn’t detailed.

Abstract
A nine-year-old dog presented with clinical signs consistent with bilateral trigeminal neuropathy. Multicentric lymphoma was diagnosed, and neoplastic lymphocytes were identified in the cerebrospinal fluid. Electromyography revealed spontaneous activity in temporal and masseter muscles. Histopathological examination demonstrated neoplastic cell invasion of temporal and masseter myofibers and of multiple peripheral nerves, including the trigeminal nerve. Central nervous system pathology consisted primarily of spinal root and leptomeningeal lymphoid cell infiltration with relative sparing of spinal cord and brain parenchyma.
