Overview
The main differential diagnosis of Arachnoid cysts are epidermoid cysts. They can be differentiated using MRIs.
Differential Diagnosis
The main differential diagnosis of Arachnoid cysts are epidermoid cysts. They can be differentiated using MRIs. Other cystic lesions of the CNS also must be differentiated.
| Intraventricularly: | Colloid cysts |
| Intraparenchymally: | Parasitic infections, cystic metastases |
| Porencephalic cysts | |
| Craniopharyngiomas | |
| Holoprosencephalies | |
| Agenesis of corpus callosum | |
| Defect in the hemispheral cleavage | |
| Dandy-Walker complex (posterior fossa cysts) |
As differential diagnosis, the following hypothesis must be considered:
- Enlarged CSF space;
- Epidermoid cyst;
- Subdural hygroma/chronic subdural hemorrhage;
- Cystic tumors;
- Pilocytic astrocytoma;
- Hemangioblastoma;
- Neurenteric cyst;
- Neuroglial cyst;
- Porencephalic cyst;
- Neurocysticercosis.[2]
