Article Synopsis
- * Out of 86 surgeries, 3D-US successfully visualized 80% of aneurysms, especially those located at the middle cerebral artery (MCA), where visibility reached 86.4%.
- * The results suggest that while most aneurysms can be seen using this technology, further research with a larger sample is necessary to validate these findings and assess their clinical significance.
Recurrent craniopharyngiomas in children and adults: long-term recurrence rate and management.
Acta Neurochir (Wien)
January 2014
Background: The significance of the majority of the factors influencing the recurrence rate (RR) of craniopharyngiomas remains unclear, and the management of this significance is controversial. The present study aimed to evaluate the influence of patient age and tumor topography on the RR, the efficacy of radiotherapy, and the safety of surgery for recurrences.
Methods: The RR was analyzed in 38 children (follow-up, 2-256 months [mean, 147.
Background: Lateral approaches to the brain stem for the resection of the cavernous malformations are preferred in order to avoid the structures within the floor of the fourth ventricle. The entry behind the pyramidal tract (PT) is usually carried out through the posterolateral surface of the brain stem. The more straightforward lateral approach below the temporal lobe is used rarely because of potential risks.

Recently, a half-way solution was added. Radical removal is reserved only for the tumors not involving hypothalamus.

Methods: MRI findings in 76 consecutive patients with craniopharyngiomas operated on between June 1991 and December 2002 were interpreted on the basis of the results of the authors' own previous microanatomic studies. The assumed tumor-3rdVF relationships were then correlated with the operative findings.
