Overview
Craniopharyngioma must be differentiated from other pituitary masses such as sarcoid, pituitary adenoma, aneurysm, teratoma, tuberculosis, rathke cleft cyst, chordoma, hypothalamic glioma, hamartoma of tuber cinereum, histiocytosis, meningioma and optic nerve glioma.
Differentiating Craniopharyngioma from other Diseases
Craniopharyngioma is a mass in the pituitary region. A simple and popular mnemonic to remember the common pituitary masses that can be confused with craniopharyngioma is SATCHMO.[1]
- S: Sarcoid, sellar tumour (pituitary adenoma)
- A: Aneurysm
- T: Teratoma or tuberculosis (and other granulomatous diseases)
- C: Cleft cyst (Rathke), chordoma
- H: Hypothalamic glioma, hamartoma of tuber cinereum, histiocytosis
- M: Meningioma, metastasis
- O: Optic nerve glioma
General imaging differential considerations include:
- Rathke cleft cyst
- No solid or enhancing component
- Calcification is rare
- Unilocular
- Majority are completely or mostly intrasellar
- Pituitary macroadenoma (with cystic degeneration or necrosis)
- Can look very similar
- Usually has intrasellar epicentre with pituitary fossa enlargement rather than suprasellar epicentre
- Despite occasional presence of T1 bright cystic regions, calcification in these cases is often absent (whereas most adamantinomatous craniopharyngiomas are calcified)
- Intracranial teratoma
- Presence of fat is helpful, but requires fat saturated sequences or CT to confirm
