[Rhinopharyngeal craniopharyngioma. CT X-ray and MRI aspects]

The authors report about a rare site of craniopharyngioma, purely extracerebral and located in the sphenoid sinus and the rhinopharynx. No CT or MRI sign is pathognomonic for the lesion, but the presence of a fleshy process containing calcifications and cystic formations must lead to evoking this diagnosis. MRI assesses the extent of the lesions perfectly, but fails to detect small calcifications or ossifications accurately.
