Co-localisation of meningioma and craniopharyngioma mimicking a single skull base tumour in an elderly patient.

According to WHO Classification meningioma and craniopharyngioma represent two distinct pathological entities. They may present the same skull base localisation therefore age distribution and peculiarity of imaging are pivotal in order to obtain a correct preoperative diagnosis. Although they are both characterized by a benign biological behaviour and a quite good prognosis, they need different and specific treatment strategies. The simultaneous occurrence of meningioma and craniopharyngioma is rare, and even more rare is their co-localisation. The authors present the case of an old female patient with concurrent craniopharyngioma and meningioma in the parasellar region mimicking a single tumour.
