Malignant peripheral nerve sheath tumour is an uncommon tumour in cats. The current case report aims to present the diagnosis, treatment and histopathology of a malignant peripheral nerve sheath tumour that developed in the cerebellopontine angle region of a cat. A 4‐year‐old 4.2‐kg female calico cat was brought to the animal hospital with the complaints of loss of balance, leaning against the wall and behavioural changes. During the neurological examination, the patient was observed to have a right‐sided head tilt accompanied by ipsilateral ventral strabismus. On magnetic resonance imaging scan, a mass was identified at the right cerebellopontine angle. The surgical removal of the mass was carried out using a caudo‐tentorial approach. The histopathological analysis revealed the presence of a malignant peripheral nerve sheath tumour. This case report contributes to the existing knowledge in the field presenting the characteristics of a malignant peripheral nerve tumour that was not associated with any nerve in the cerebellopontine angle in a cat.
