Differential Diagnosis
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.
- Eventually, arachnoid cysts may contain proteinaceous fluid or blood, which can cause diagnostic confusion.[1]
| 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.[3]
