Overview
CT
- Cranial magnetic resonance imaging (MRI): An MRI uses magnetic fields but it is a different type of image than what is produced by computed tomography (CT). It can produce very detailed images of the brain to help diagnose craniopharyngioma. Like computed tomography (CT), a contrast agent may be injected into a patient’s vein to create a better picture.
- Cranial computed tomography (CT) scan: CT scans are also used to diagnose craniopharyngioma. It can confirm the location of the tumor and show the organs nearby.
- Endocrine hormone tests
- Adamantinomatous-type tumor appears as a predominately cystic mass with a solid component (>90%).
- The solid component appears isoattenuating and usually contains calcifications (>80%).
- The sella may be expansile
- Hydrocephalus may be present
- Contrast enhancement is characteristic of the solid component and cyst wall (90% cases)
- Papillary type is usually solid, isoattenuating, and rarely calcified.
