“…Congenital arachnoid cysts (CAC) account for 1% of all intracranial space-occupying lesions [19,29]. Some are found incidentally at autopsy [11,19,29], However, with improved diagnostic methods more of these are discov ered [8,19,29], Most cysts are discovered in the first 2 decades of life [13,29,30,43] with as many as 60-80% being discovered by 16 years of age [32].…”

“…The incidence is greater in males than females [13,30,43]. Most cysts are in the middle cranial fossa [6,29,44], the next most common site being the posterior cranial fossa [6,29], Bilateral middle cranial fossa cysts and retroclival cysts are very rare; only nine cases of the former have been reported [28,39].…”

“…A number of theories have been proposed to explain the etiopathogenesis of these lesions [6-8, 16, 18, 19,29, 32, 35,40,44], Abnormal splitting of the arachnoid and subsequent cerebrospinal fluid (CSF) flow during de velopment and an aberration in the formation of CSF spaces are widely accepted [29,32,35,44], Their close relation to the major subarachnoid cisterns lend support to the above theories. The clinical and radiological fea tures of this condition have been well described [1,2,4,7,11,15,16,19,20,24,26,47,51].…”

Congenital arachnoid cysts (CAC) are benign developmental disorders. A number of theories have been proposed to explain the origin and progression to the symptomatic stage. Management strategies range from not treating the asymptomatic cysts to craniotomy, excision of cyst wall and establishment of a communication with the adjacent subarachnoid cistern or ventricle. Other lesions may resemble CAC, and can be differentiated from CAC only by a critical review of the biopsy specimen. We have reviewed our experience with true CAC and similar lesions. Based on our experience we recommend craniotomy, excision of cyst wall and establishment of a communication with an adjacent subarachnoid cistern or ventricle as the primary procedure.

“…6 An arachnoid cyst is an intracranial benign, nongenetic developmental cyst which contains spinal fluid and occurs within the arachnoid membrane. 7 The exact mechanism of formation during embryogenesis is still unclear. Postulated mechanisms of the enlargement of these cysts include secretion by the cells forming the cyst walls, a one way valve, or liquid movements secondary to the pulsations of the veins.…”

Guillain–Barre´ syndrome with bilateral facial palsy with incidental arachnoid cyst

et al. 2015

This case report describes the findings of a 10-year-old female child admitted with fever and headache for 3 days along with several episodes of vomiting and generalized seizures for 1 day. She regained consciousness 50 minutes after admission with initial treatment, but developed muscle weakness, followed by tetraplegia with areflexia, bilateral facial palsy and respiratory insufficiency. The nerve conduction study (NCV) had evidence of demyelinating neuropathy and the cerebrospinal fluid (CSF) showed albumin-cytological dissociation. These neurologic findings were consistent with the diagnosis of Guillain-Barré syndrome. The patient was treated with immunoglobulin and other supportive cares. Mechanical ventilation was started on day 3 of hospital admission in face of respiratory insuficiency. Recovery, however, was relatively quick and extubation was possible on 6th day. Work up for CNS infection was non-contributory. MRI of brain done during the course, revealed an archnoid cyst in right temporal region which might have contributed to the episode of unconsciousneess, vomiting and convulsion. After two weeks of hospitalization the patient was discharged from the hospital on wheel chair with satisfectory improvement of powers of facial and limb muscles. When the patient was seen at the outpatient department four weeks after hospital discharge, she was able to walk with help with normal facial nerve function on both sides. G B syndrome presenting like meningitis; bilateral facial palsy; and co-presence of an archnoid cyst makes this case worth sharing.DOI: http://dx.doi.org/10.3126/ajms.v6i5.11627Asian Journal of Medical Sciences Vol.6(5) 2015 71-74

Neurosurg Focus 40 (4):E9, 2016S port-related concussion (SRC) has emerged as a public health problem, affecting athletes of all ages and participation levels. 11,35,43 While SRC by definition includes normal imaging results, a minority of sportrelated head injuries result in structural brain injury. 3,18,19,84,85 These cases are often neurosurgical emergencies and can result in permanent neurological deficit and/or death. Recent literature has postulated that athletes with arachnoid cysts (ACs) demonstrate a higher rate of structural brain injury after trauma, specifically subdural hematoma (SDH) or hygroma. 37,44,79 ACs are congenital lesions bordered by an arachnoid AbbreviAtioNs AC = arachnoid cyst; ICP = intracranial pressure; IPH = intraparenchymal hemorrhage; IQR = interquartile range; PCS = postconcussion syndrome; SDH = subdural hematoma; SRC = sport-related concussion. objeCtive Arachnoid cysts (ACs) are congenital lesions bordered by an arachnoid membrane. Researchers have postulated that individuals with an AC demonstrate a higher rate of structural brain injury after trauma. Given the potential neurological consequences of a structural brain injury requiring neurosurgical intervention, the authors sought to perform a systematic review of sport-related structural-brain injury associated with ACs with a corresponding quantitative analysis. MethoDs Titles and abstracts were searched systematically across the following databases: PubMed, Embase, CINAHL, and PsycINFO. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Peer-reviewed case reports, case series, or observational studies that reported a structural brain injury due to a sport or recreational activity (hereafter referred to as sport-related) with an associated AC were included. Patients were excluded if they did not have an AC, suffered a concussion without structural brain injury, or sustained the injury during a non-sport-related activity (e.g., fall, motor vehicle collision). Descriptive statistical analysis and time to presentation data were summarized. Univariate logistic regression models to assess predictors of neurological deficit, open craniotomy, and cystoperitoneal shunt were completed. resUlts After an initial search of 994 original articles, 52 studies were found that reported 65 cases of sport-related structural brain injury associated with an AC. The median age at presentation was 16 years (range 4-75 years). Headache was the most common presenting symptom (98%), followed by nausea and vomiting in 49%. Thirteen patients (21%) presented with a neurological deficit, most commonly hemiparesis. Open craniotomy was the most common form of treatment (49%). Bur holes and cyst fenestration were performed in 29 (45%) and 31 (48%) patients, respectively. Seven patients (11%) received a cystoperitoneal shunt. Four cases reported medical management only without any surgical intervention. No significant predictors were found for neurological deficit or open cr...
