Neuroradiology case approach-Haemangioblastoma
Young male with headache
Differentials include
Vein of galen aneurysm-
- normally presents early
- straight sinus will be full and dilated
- multiple flow voids with thrombosis likely
- Sup sag sinus will also be full
- DW could show penumbra of restriction
Pilocytic astrocytoma----------possible
- unusual location
- Flow voids unusual as it is low grade tumour
- perilesional oedema possible
Epidermoid---------------------possible
- No restriction on diffusion
- normally does not enhance
Pineal gland tumour-------possible
- usually midline
- heterogenous enhancement
- goes to flooor of third ventricle
What we suggested is haemangioblastoma
- unusual location
- nodule is typical
- Bleed not present
- no oedema usually
