An unusual case of subdural haematoma presenting to the accident and emergency department

Abstract

A case of subdural haematoma associated with an intracranial arachnoid cyst is reported. The pathogenesis, clinical presentation and treatment options of intracranial arachnoid cysts is discussed.

Chronic subdural haematoma associated with arachnoid cyst of the middle fossa in a soccer player: Case report and review of the literature

“…13 patients on admission presented with CSDH [5,[7][8][9][10][11][12][13][14][15][16]18,19]. 11 patients had midline shift [5,[7][8][9]11,12,15,16,18], in 1 case the midline structure was on axis [10]. and in 2 cases there was no mention on midline shift or other signs of raised intracranial pressure [14,19].…”

“…Six patients underwent an open craniotomy with cyst fenestration [5,7,8,11,13,19] In one of these, the patient with the subdural hygroma and midline shift, a cistoperitoneal shunt was also performed [13]. In one case the surgical procedure was not well speci ied [10]. In the case of subdural hygroma with no midline shift, a conservative treatment was done [17].…”

“…1,2,12 The interval from onset until diagnosis of pediatric subdural hematomas due to sports-related injury has ranged from several hours to several months. 1,2,13 There are several theories as to why arachnoid cysts cause these bleeding events. 3,9,10 One theory is that the walls of the cyst are stiffer than surrounding brain tissue, making for easier distention and rupture of adjacent bridging veins.…”

Intracranial arachnoid cysts: Clinical study with the findings of 32 surgically treated cases

“…They may tear and bleed spontaneously (or after a relatively minor head trauma) into the cyst (intracystic hemorrhage), causing its size to increase. If a blood vessel bleeds on the outside of a cyst, a collection of blood (subdural or subarachnoid hemorrhage) may result [9,27,28] (Fig. 3).…”
