[Clinical manifestations and imaging features of peripheral vestibular paroxysmia: a report of 7 cases].

OBJECTIVE

To investigate the clinical manifestations and imaging features of peripheral vestibular paroxysmal (PVP).

METHODS

The clinical data, including magnetic resonance tomographic angiography (MRTA), of 7 PVP patients, 1 male and 2 females, aged 40-72, were retrospectively analyzed.

RESULTS

(1) All 7 patients had non-specific cochleovestibular symptoms, e.g., recurrent vertigo and continuous dizziness. (2) The predominant symptom was transient vertigo or dizziness with the sudden change of head position. (3) MRTA showed cross of the cochleovestibular nerve (CNV) and blood vessel in all patients. (4) Carbamazepine and sibelium succeeded to relieve the symptoms.

CONCLUSION

Compression of the cranial nerve VIII by crossing vessel thereon may be the mechanism of PVP which can be identified and diagnosed clinically.
