Extracranial craniopharyngeoma. A-C: Coronal, axial and sagittal reconstructions of a spiral CT scan. Note the expansively growing mass with calcifications, thinning and remodeling of the walls of the pterygoid processes, predominantly on the right side, and the anterior parts of the clivus with preserved posterior margin. D and F: Axial and sagittal contrast-enhanced T1-weighted images from a 3D data revealing a partly solid and cystic mass of the clivus and sphenoid cavity with expansion into the ventral the ethmoid sinuses and the nasal cavity, caudally limited by the plane of soft and hard palate and cranially by the sella. E: Early arterial phase of a time resolved contrast-enhanced MR angiography to exclude an juvenile angiofibroma. Neither pathological arterial vessels nor arteriovenous shunts were visible.
