Tumor Kleinhirnbrückenwinkel
Schwannom am
Kleinhirnbrückenwinkel rechts (links im Bild) in der MRT T1KM axial.
A rare cause
of infant facial paralysis: atypical teratoid rhabdoid tumour located in the cerebellopontine angle. a–d On the brain MRI, a dural-based, extra-axial mass lesion was observed on the left CPA, 4 × 3 cm in size, with heterogenous contrast after the application of IV contrast dye, which was heterogenous-hypointense on T1W and FLAIR sequences, heterogenous hyperintense on T2W, the mass appears to enter the cavernous sinus via Meckle’s cave. Time there is concomitant calcification, bleeding and oedema of the surrounding

Mnemonics
AMEN/MEAN
- A: acoustic neuroma (a.k.a. vestibular schwannoma) (~80%)
- M: meningioma (~10%)
- E: ependymoma (~5%)
- N: neuroepithelial cyst (arachnoid/epidermoid) (~5%)
SAME
- S: schwannoma
- vestibular schwannoma much more common than a trigeminal schwannoma
- A: aneurysm, arachnoid cyst
- M: meningioma, metastasis
- E: epidermoid cyst, ependymoma
ANGLES
- A: aneurysm, arachnoid cyst
- N: (it's almost M) - meningioma, metastasis, medulloblastoma
- G: glioma (brainstem glioma)
- L: lymphoma
- E: ependymoma, epidermoid cyst
- S: schwannoma
