title: Hyperostotic paraganglioma of occipitotemporal bone.
abstract: A 25-year-old male presented with off-and-on vertigo of 10-year duration. He had left-sided cerebellar signs, left vocal cord paresis, and minimal left-sided hearing impairment. Computed tomography of the head revealed significant hyperostosis of squamous occipital, mastoid, and petrous temporal bone with no adjacent soft tissue mass. On excision, it turned out to be paraganglioma. Paraganglioma as a pure bony mass is not reported in the literature. The site of origin of such a tumor could not be ascertained, even on generous screening. The tumor remained nonsecretory on clinical and biochemical investigations.
