Pendred's syndrome with episodic vertigo, tinnitus and vomiting and normal bithermal caloric responses.
A case of early-onset bilateral sensori-neural deafness with episodic objective vertigo, tinnitus and vomiting, suggestive of Menière's syndrome, was found to have a diffuse goitre. A Perchlorate discharge test was positive, indicating an organification defect diagnostic of Pendred's syndrome. The case was found to be euthyroid both clinically and on investigations. Tone decay was absent and recruitment was found, thus indicating a cochlear site of lesion. Bithermal caloric tests and clinical tests of vestibular function were within normal limits. X-rays, including petrous tomography, did not show any abnormalities.
