title: [Chemodectoma of the pterygo-maxillary fossa].
abstract: Cervicocephalic chemodectomas are rare non-chromaffin paraganglionic tumours, most often originating in the carotid body or the jugular ganglion. Their main features are a reluctance to invade adjacent tissue and the absence of general clinical signs. Since they are histologically quite varied they may at times be difficult to recognise. A chemodectoma of a hitherto unreported type is described. Encountered in the pterygo-maxillary fossa it was identified by computerised axial tomography and angiography.
