Bilateral Subdural Hygroma in a Case with Sylvian Arachnoid Cyst
ثبت نشده
چکیده
Arachnoid cysts are congenital lesions developing from arachnoid membrane. The incidence of arachnoid cysts in the general population is around 0.1% and their most common place is middle fossa. Arachnoid cysts usually present during childhood and are identified incidentally. When symptomatic, the most common presentation includes headache and seizure. The popular treatment for this lesion is surgery. In this case report, we describe a 12-year-old boy with a middle cranial fossa arachnoid cyst presenting with progressive headache, and bilateral subdural hygroma following a trivial trauma.

Symptomatic Unilateral Subdural Effusion as the First Presentation of Suprasellar Arachnoid Cyst
Background and Importance: Arachnoid cysts are benign nontumoral lesions that are usually found incidentally in brain imaging. 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...

متن کاملTwo case series reports: 8 cases of arachnoid Temporoparietal cysts (middle fossa & sylvian fissure) and 2 cases of chronic subdural hematoma
Background: Arachnoid cysts are common intracranial space-occupying lesions which are often found in middle fossa and temporal regions of the skull. Many of these lesions are asymptomatic but some might appear as spaceoccupying lesions. Almost arachnoid cyst rupture, either following a trauma or spontaneously can result in intracystic hemorrhage, subdural hematoma and hygroma. The present study...
متن کاملCase Report Sylvian arachnoid cyst typing and neuroendoscopic fistula surgery treatment
Objective: To propose a new typing method for sylvian arachnoid cysts (SACs) and to provide a basis for the choice of surgical approaches of SACs. Methods: 34 cases of SACs were divided into 3 types: I type. SACs medial cyst wall was located in the outer 1/3 of sylvian fissure; type II. SACs medial cyst wall was located in median 1/3 of sylvian fissure; III type. Type I and Type II accepted neu...
