Purpose of this study is to investigate whether intraoperative imaging using a 1.5T MRI in craniopharyngioma surgery is useful in order to increase the rate of complete tumor removal.

Primary Outcome Measures:
- Rate of additional tumor removal [ Time Frame: up to 3-4 months following surgery ] [ Designated as safety issue: No ]Number of patients in whom non suspected tumor remants were indicated by intraoperative MRI and remnants could be removed completely thereafter. Results have to be confirmed in 1st follow up imaging.
- Rate of achievement of intended extent of removal [ Time Frame: up to three months following surgery ] [ Designated as safety issue: No ]It is examined whether the extent of tumor removal defined prior to surgery was achieved
- Diagnostic reliability [ Time Frame: within 3 -4 months following surgery ] [ Designated as safety issue: No ]false positive or negative interpretation of intraoperative imaging determined after follow-up imaging 3 - 4 months following surgery
Secondary Outcome Measures:
- Surgical complication [ Time Frame: within 1st week following surgery ] [ Designated as safety issue: No ]Rate of new deficits following surgery (excluding new endocrine deficits)
