“…Ammar et al reviewed cases of spontaneously resolved ACs prior to 2020 and found that up to 85% of cases occurred in children. 4 To date, only one case of spontaneous resolution of a CPA AC has been reported in an 11-month-old child by Takagi et al 5 Our case represents the first documented case of a symptomatic CPA AC resolved without intervention in an adult.…”

Arachnoid cysts (ACs) account for 1% of all intracranial masses, and majority of cases are asymptomatic. 1 In adult, symptomatic AC often requires surgical intervention, with spontaneous resolution being a rare occurrence. Here, we present the first documented case of spontaneous resolution of a symptomatic cerebellopontine angle (CPA) AC in adult, with subsequent recovery of neurological deficits.

“…However, it is worth noting that spontaneous resolution, expansion, and rupture of cysts have all been reported. [13][14][15] Although there is a lack of class I evidence regarding the optimal treatment of arachnoid cysts, it is generally agreed that if the cyst is symptomatic due to the presence of hydrocephalus, neurological deficits, or localized seizures, surgical management is indicated. For asymptomatic cysts, observation is recommended, although the benefit of repeat imaging past the age of 4 years is controversial.…”

Infection of arachnoid cyst associated with vasospasm and stroke in a pediatric patient: case report

Arachnoid cysts are relatively common and benign intraarachnoid membrane outpouchings containing CSF-like fluid. The majority of arachnoid cysts remain stable and asymptomatic and do not require intervention in the pediatric population. Here, the authors present the first reported case of an infected arachnoid cyst in a pediatric patient resulting in severe vasospasm of the left terminal internal carotid artery, left A1 segment, and left M1 branches with a left middle cerebral artery infarct. Their experience suggests that close monitoring is warranted for this condition and that the pediatric population may be at higher risk for vasospasm.

Background Intracranial arachnoid cysts are benign collections of cerebrospinal fluid that are often asymptomatic and discovered incidentally. An interhemispheric location of these lesions is rare, with only a few such cases reported in the literature. Though spontaneous regression of arachnoid cysts has been described in other locations, to date this phenomenon has not been reported in interhemispheric fissure cysts. Observations In this report, we describe a patient with a large, multiloculated interhemispheric arachnoid cyst diagnosed on prenatal ultrasound. She did not exhibit neurologic deficits or signs of increased intracranial pressure and was observed with serial imaging. After several years of observation, imaging revealed spontaneous and progressive decrease in the cyst size. Lessons We illustrate a case of regression of an interhemispheric arachnoid cyst in a pediatric patient. To our knowledge, this is the first reported case of spontaneous shrinkage of an arachnoid cyst in this location. Although the current presentation is rare, this reporting adds to the current understanding of natural history of arachnoid cysts and provides an example of radiographical improvement without intervention of a cyst located within the interhemispheric fissure.
