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.
作者报告了一例颅咽管瘤的罕见部位，肿瘤完全位于脑外，位于蝶窦和鼻咽部。对于该病变，没有CT或MRI征象具有确诊意义，但出现含有钙化和囊性结构的肉质肿物时必须考虑这一诊断。MRI能很好地评估病变范围，但无法准确检测出小的钙化或骨化。
