Chronic subdural hematoma associated with type II and type III Galassi arachnoid cysts: illustrative cases

Bac Thanh Nguyen, Van Dinh Tran, Jehan Bista, and Trung Van Trinh

, hydrocephalus, and epileptic seizures. 2 The diagnosis of asymptomatic ACs has increased in recent years due to the extensive utilization of computed tomography (CT) and magnetic resonance imaging (MRI) techniques. 3 Head trauma is one of the most significant risk factors for the development of intracystic hemorrhage in ACs and subsequent subdural hematoma (SDH). However, fewer than 182 cases of spontaneous intracystic hemorrhage have been reported in the literature. 3 , 4 In this report, we present illustrative cases of three young patients who experienced spontaneous AC

Intracranial subdural hemorrhage following closed neural tube defect repair: illustrative case

Stacey Podkovik, Jonathon Cavaleri, Carli Bullis, and Susan Durham

Intradural spine surgeries are extremely common procedures within the fields of both adult and pediatric neurosurgery. Distant intracranial extraaxial hemorrhages are a known, but uncommon, complication after intradural spinal procedures. Most of these occurrences are typically due to an iatrogenic cerebrospinal fluid (CSF) leak leading to intracranial hypotension. 1 The incidence of subdural hematoma (SDH) in the setting of intracranial hypotension is approximately 10%. 1 However, the incidence of SDH after intradural spine surgeries is reported to be as

Spontaneous rupture of an arachnoid cyst in an adult: illustrative case

presentation for symptomatic patients, although arachnoid cysts may also cause hydrocephalus, neuropathies, seizures, cognitive complaints, and other focal neurological deficits. 1 , 2 Rarely, arachnoid cysts can present as a neurosurgical emergency due to cyst rupture with subsequent intracystic hemorrhage or subdural hematoma causing mass effect or a rapid rise in intracranial pressure. 1 , 3 Few documented reports of spontaneous arachnoid cyst hemorrhages exist as this predominantly occurs following head trauma. 1 , 4 In this report, we describe a patient who presented

Acetazolamide to treat symptomatic ruptured arachnoid cysts: illustrative cases

Isabella Watson, Patrick J. McDonald, Paul Steinbok, Brendon Graeber, and Ashutosh Singhal

ruptured ACs, intervention may be needed. 5 Particularly in the case of an AC rupture, there is a risk of intracystic hemorrhage, subdural hematoma, or subdural hygroma, which can cause raised intracranial pressure (ICP) and lead to adverse neurological symptoms. 5 The optimal treatment for a ruptured AC remains controversial, and a consensus has yet to be reached on whether a conservative, nonoperative, or surgical approach is most effective. Because ruptured ACs are relatively uncommon, there is limited literature on treatment options and treatment effectiveness

Nontraumatic symptomatic de novo arachnoid cyst in an adolescent patient treated with cystoperitoneal shunting: illustrative case

Angelica M Fuentes, Jonathan J Yun, and John A Jane Jr.

. One less frequently reported cause of arachnoid cysts is chronic ventricular shunting. One case report described such a patient who developed subdural hematoma and arachnoid cyst after having had a ventriculoperitoneal shunt in place for approximately 7 years. 17 Although possible, CSF overdrainage is not likely the cause of arachnoid cyst development in the present case. Other signs of CSF overdrainage, including decreased ventricular caliber and the formation of subdural collections, were not observed in our patient. To date, there has been no reporting of
