Suprasellar Arachnoid Cysts (SSACs) are rare. They can cause hydrocephalus and increased intracranial pressure, lower cranial nerve impairment and endocrine disorder. Sometimes arachnoid cysts become complicated by subdural hematoma/hygroma. Case Presentation: We describe a patient with a suprasellar arachnoid cyst that was complicated with symptomatic subdural effusion and increased intracranial pressure after minor trauma. Conclusion: Although these cysts are rarely complicated with subdural hematoma/hygroma, and intracystic hemorrhage, the probability of subsequent subdural hygroma and increased intracranial pressure should not be underestimated. }, URL = {http://irjns.org/article-1-92-en.html}, eprint = {http://irjns.org/article-1-92-en.pdf}, journal = {Iranian Journal of Neurosurgery}, doi = {10.29252/irjns.3.3.115}, year = {2017} }
