“…AC may develop rapidly in utero [17, 18] or appear after birth [19], and they may be associated or not with underlying brain hypoplasia [18]. Nonetheless, their association with other congenital diseases [7, 8] such as atretic cephalocele [20] suggests the possibility of a genetic basis at least in some cases.…”

Although hearing loss in newborns and infants is predominantly due to malformations and infections, there are other situations which may compromise hearing quality in later stages, including posterior-fossa arachnoid cysts (ACs). We report the case of an 8-year-old girl who presented with hearing loss linked to a pontocerebellar-angle AC which had been diagnosed and treated when she was 14 months old. The pathophysiology of this late AC complication is discussed. This case reminds us that a close follow-up with audiologic monitoring and/or brain stem auditory evoked response is necessary in children with posterior-fossa AC because modern neuroradiological imaging methods do not inform about cerebral and nerve functions, although they provide excellent morphological details of ACs and have improved the ease and accuracy of their early diagnosis. Therefore, surgery should be performed before complete hearing loss occurs; however, in hearing-impaired patients, it remains unclear which surgical treatment is most appropriate.

“…1 Galassi et.al has described the classification system of arachnoid cyst based upon its size, shape & communication with the cistern. 2,3 Type I sylvian arachnoid cyst has biconvex appearance which is freely communicated with cistern & are best managed conservatively. Type II sylvian arachnoid cyst are rhomboid shaped & partially communicated with cistern.…”

“…Type III sylvian arachnoid cyst are huge in size with mass effect & no communication with cistern, hence surgical treatment are advised to deal this type of arachnoid cyst. 2,3 Various surgical treatments are available & all of them have showed relatively similar outcome in terms of its recurrence & morbidity. Cystoperitoneal shunt, marsupilization of cyst, fenestration of cyst with the nearby cistern either endoscopically or microsurgically, arachnoidoplasty, are the various surgical options available.…”

Arachnoid cyst is a benign congenital lesion which can be located in various regions like; suprasellar, sylvian, posterior fossa, spine & so on. The most common location of arachnoid cyst is the middle fossa or sylvian fissure usually behind the greater wing of sphenoid bone (50%). Here we are presenting a case of a 59 year-old woman brought to the emergency department with history of sudden onset loss of consciousness associated with generalized tonic clonic seizure. CT-scanning of head showed Galassi type 3 arachnoid cyst. She was managed with fenestration and partial marsupialization of cyst with excellent outcome.

“…These disorders are thought to result from the mass effect of the cyst on the hypothalamus and infundibulum. Suprasellar arachnoid cysts have been classifi ed as communicating or noncommunicating based on CT cisternography and pneumoencephalography [10,11] . Communicating cysts contain the basilar apex and represent an aberrant dilatation of the interpeduncular cistern.…”

Hypothalamic Hamartoma in Association with a Suprasellar Arachnoid Cyst: A Case Report

et al. 2005

View full text Add to dashboard Cite

A 5-year-old female presented with a history of precocious puberty and increased height. MRI of the brain revealed a nonenhancing hypothalamic mass and associated suprasellar arachnoid cyst. The patient underwent a right frontal craniotomy with orbital osteotomy for wide fenestration of the cyst. Intraoperatively, it was clear the mass represented a hamartoma with a very smooth glistening surface. For this reason, no biopsy of the wall was performed. Postoperatively, the patient remains neurologically intact and without any medication dependence. This case highlights the occurrence of a suprasellar arachnoid cyst in association with a hypothalamic hamartoma.
