Article Synopsis
- * There are two main types of craniopharyngioma: adamantinomatous, which is common in children and linked to mutations in the CTNNB1 gene, and papillary, which mainly affects adults and is associated with BRAF mutations.
- * Treatment requires specialized centers to balance effective tumor removal with the preservation of critical brain function, and while surgery is essential, radiotherapy is used to minimize recurrence, alongside emerging targeted medical therapies.

Article Synopsis
- A study was conducted on pediatric patients with sellar-suprasellar tumors to create a deep learning algorithm for better classification using MRI images.
- 226 Chilean patients were analyzed, categorized into three groups: healthy controls, craniopharyngioma, and other sellar/suprasellar tumors.
- The findings showed a high predictive positive value (PPV) and negative predictive value (NPV) for the algorithm, highlighting the potential of explainable AI in assisting radiological diagnoses.
