“…Of the five cases in which patients presented with symptoms referable to the identified thalamic cyst, in four the primary complaint was a movement disorder-most commonly a contralateral upper-extremity tremor. 4,8,15,16 In contrast to our series, hydrocephalus was present in only one of the five cases. 9 On the whole, the surgical management of symptomatic intracranial cysts (including neuroepithelial, colloid, and arachnoid cysts among others) has varied widely.…”

“…1,4,12,14,15,19 Although this frequently proved to be effective, a desire for a less invasive method of treating these lesions led to later reports of stereotactic aspiration and internal or external drainage via a shunt or reservoir system. [7][8][9]16 In the cases treated by Heran, et al, 8 stereotactic aspiration proved to be less effective with both patients experiencing symptomatic worsening reflective of cyst enlargement. One patient declined additional surgical management, whereas the other underwent a second attempt at stereotactic aspiration and ultimately placement of an intracystic Ommaya reservoir when her symptoms returned a second time.…”

“…7 Nevertheless, the treatment of symptomatic lesions has varied according to their locations and the surgical treatment available. Surgical management has yielded mixed results and has included stereotactic aspiration, 8,13,16 internal drainage via placement of a cystosubarachnoid or cystoventricular shunt, 9,20 external drainage via a reservoir system, 8,9 craniotomy with cyst resection and/or fenestration, 1,3,4,12,14,15,19 and endoscopic cyst fenestration into an adjacent subarachnoid or ventricular space. 5 In this paper we describe three cases of symptomatic thalamic neuroepithelial cysts associated with hydrocephalus.…”

Thalamic neuroepithelial cysts are rare lesions of the central nervous system. Surgical management of these lesions has varied and yielded mixed results. The authors identified 10 reported cases in the literature, five of which involved symptomatic lesions. The authors present three unique cases of symptomatic thalamic neuroepithelial cysts associated with hydrocephalus, which were all successfully treated using endoscopic third ventriculostomy and fenestration of the cyst into the third ventricle.

“…4 Most neuroepithelial cysts are asymptomatic, 2 however some may present with seizures, 5,6 mass effect 7,8,9 or rarely with movement disorders. 10,11,12 They usually present late in their course because of slow growth and lack of pericystic edema. One case of acute hydrocephalus due to hemorrhage into a thalamic cyst has been reported.…”

Background:The authors present two cases of movement disorders caused by neuroepithelial cysts and highlight their management. Neuroepithelial cysts are ependymal or epithelial lined fluid collections of unknown etiology within the central nervous system parenchyma with no obvious ventricular or subarachnoid connection. Most cysts are asymptomatic, however, some present with seizures, mass effect, or rarely with movement disorders.Case Reports:The first patient, a 27-year-old female, presented with progressive weakness, dystonic posturing, tremor, ballismus and choreoathetotic movements of her right upper extremity. Her symptoms improved after stereotactic drainage of a neuroepithelial cyst in her basal ganglia but recurred within a year. The second case, a 56-year-old female, presented with diplopia, nystagmus, gait imbalance and hemiparesis. Her symptoms improved after stereotactic drainage of a midbrain neuroepithelial cyst. The cyst reaccumulated over the next few years and she became symptomatic with left arm tremor and facial weakness. Aspiration was again performed with symptomatic improvement for nine months. Her tremor recurred and a cyst access device was placed stereotactically. She improved and has remained stable for over a year.Conclusion:Simple stereotactic drainage of neuroepithelial cysts has a high recurrence rate. The authors recommend considering placement of a drainage device to facilitate aspiration of the cyst fluid during follow-up, if needed.

“…Even there are previous publications reporting the use of stereotactic aspiration as a single treatment of deep-seated benign cysts with characteristics of glioependymal cysts [1][2][3]. The results of these studies show a high cyst recurrence after stereotactic drainage, which also happened in the second case presented by Apra et al…”

We thank the authors for their interest in our article [4] and for submitting their comments and suggestions related to the treatment of glioependymal cysts. The authors of the letter suggest that stereotactic drainage of glioependymal cysts can be considered as a first-line option in the treatment of these lesions.We should clarify first that our review included only cases with histopathological confirmation of glioependymal cyst, and cases without histological analysis were eliminated from the study. As consequence, we could have excluded cases treated in different ways if histological analysis was not performed. In our study, we did not find cases treated in the way described by Apra et al., but this does not mean that cases treated in this way do not exist.Due to the rarity of these lesions, treatment of glioependymal cysts is not standardized which is corroborated by the multiple surgical strategies that exist in the management of these cysts. Even there are previous publications reporting the use of stereotactic aspiration as a single treatment of deep-seated benign cysts with characteristics of glioependymal cysts [1][2][3]. The results of these studies show a high cyst recurrence after stereotactic drainage, which also happened in the second case presented by Apra et al.In their first case, a cyst located in the cerebellar peduncle was treated with stereotactic aspiration showing long-lasting clinical improvement in the patient; in addition, the cyst has not shown recurrence on imaging after 4 years. Although histopathological study was not performed in this case, the images are very suggestive of an ependymal or glioependymal cyst.Due to the aforementioned, we believe it is very risky to consider stereotactic aspiration as a first-line strategy in the management of glioependymal cysts based only on the results of a single case.We do not deny that stereotactic aspiration can be useful as initial treatment, especially for the management of cysts located in deep and functional brain areas; however, we consider a more definitive option preferable, such as the fenestration of the cyst into cerebrospinal fluid spaces.We greatly appreciate Apra et al.'s observations regarding the management of glioependymal cysts.
