The effect of radiation on the vestibular apparatus of animals and man have not been widely investigate. Referred symptoms are disequilibrium and spontaneous nystagmus in animals while histological features are intralabyrinthic haemorrhage, edema of the endolymphatic spaces and alterations of sensory hair cells. A group of 20 patients with head and neck cancer located in different sites (nasal cavity, oropharynx, oral cavity, parotid gland) underwent to vestibular investigations before and 3-6 months after radiation therapy. Ten patients (50%) showed an alteration of the vestibular function of peripheral origin after radiation treatment. Complications appeared from a few weeks up to several months following termination of radiotherapy. The slow development of the lesion permitted central compensation. Few patients had symptoms and vestibular symptomatology was always of secondary importance with respect to the initial pathology.

Paraneoplastic cerebellar degeneration is a rare neurological disorder that frequently precedes the detection of malignancy. Here, we report the case of a 60 year-old woman with locally advanced squamous cell carcinoma of the tongue who developed a subacute cerebellar syndrome associated with the presence of anti-CV2/CRMP5 antibodies in the cerebrospinal fluid, after achieving complete remission of the primary tumor and the involved cervical lymph nodes by chemoradiation. The patient's symptoms on presentation were dizziness and gait unsteadiness. On examination she showed dysarthria, nystagmus and limb and gait ataxia. The diagnosis of paraneoplastic cerebellar syndrome was made on the basis of the clinical findings and immunological testing that revealed the presence of anti-CV2/CRMP5 antibodies in the patient's cerebrospinal fluid. This syndrome, which is very rare in association with head and neck cancer, commonly precedes the detection of malignancy by a year or more and has been documented in only a few cases after completion of anticancer treatment.
