文摘

To evaluate cognitive outcome in children after surgical decompression of arachnoid cysts of the middle cranial fossa. An additional objective was to assess the children as one part of the decision whether to perform a surgical intervention or not. Arachnoid cysts are often considered asymptomatic incidental findings of MRI or CT. In this project the aim was to assess prevalence of cognitive symptoms correlated to the cyst and possible postsurgical improvement.

Methods

Neuropsychological assessment at the department of child neurology at Karolinska University Hospital, Stockholm. The assessment of intellectual ability was done using WISC-IV. Assessment of specific cognitive functions was done using NEPSY-II, Rey Oesterrieth Complex Figure test, BNT-II and FAS (test of verbal fluency). A follow-up with the same psychometric tests 4–5 months after surgery.

Results

To this date 6 children has gone through presurgical assessment. Four of six children showed cognitive symptoms in the assessment. Symptoms that was correlated to the location of the cyst and the neurosurgeon decided on fenestration of the cyst. Two of six children had no cognitive symptoms and the neurosurgeon decided on no surgical intervention. Two of the four children with symptoms have been evaluated 5 months after decompression of the cyst. Both clinical and psychometric results points towards reduction of cognitive symptoms in these two patients.

Conclusion

Neuropsychological assessment might be used as a help in decisions regarding surgery. Pre- and post-op assessment might be a way of evaluating the possible benefits of decompression of arachnoid cysts of the middle cranial fossa in children.
