Arachnoid Cyst Is a Risk Factor for Chronic Subdural Hematoma in Juveniles: Twelve Cases of Chronic Subdural Hematoma Associated with Arachnoid Cyst

Abstract: Chronic subdural hematoma (CSDH) tends to occur in elderly patients with a history of mild head injury at a few months prior to the onset of symptoms. Intracranial arachnoid cyst is believed to be congenital and sometimes becomes symptomatic in pediatric patients. These two distinct clinical entities sporadically occur in the same young patient. Twelve of 541 cases of CSDH surgically treated in our institution had associated arachnoid cyst. The clinical and radiological characteristics of the cases of CSDH ass… Show more

“…However, arachnoid cysts can be associated with the development of symptomatic subdural hygromas and subdural hematomas. [4][5][6] These subdural abnormalities are thought to occur due to rupture of an arachnoid cyst and in the case of subdural hematoma hemorrhage into the subdural space, associated with trauma. The reported risk of subdural hematoma in patients with arachnoid cyst is 8 to 17%.…”

“…The reported risk of subdural hematoma in patients with arachnoid cyst is 8 to 17%. 6 Hence, it is currently not recommended to surgically treat arachnoid cysts to prevent cystic hygroma and subdural hematoma. It is, however, recommended that patients with arachnoid cyst try to avoid head trauma.…”

“…Both had favorable outcomes 4 . When emergency surgery is necessary for patients with AC and subdural hematomas the direct approach to the AC is usually not necessary, because the cyst frequently decreases or disappears after the evacuation of the hematoma or hygroma 4,13,14 . This is the expected outcome for intracystic or ipsilateral hematomas, which are different of the contralateral hematoma of our patient.…”

“…Hemorrhage may occasionally occur into an arachnoid cyst after trauma. [97][98][99][100] Because this is also a very rare event, prophylaxis against future hemorrhage risk should not be used to justify surgical treatment in an asymptomatic child. Furthermore, hemorrhages associated with arachnoid cysts are associated with generally good outcomes, even when surgical evacuation of the hemorrhage is deemed necessary.…”
