  "account": "Hajebian and Friel (Journal of Craniofacial Surgery, published 16 January 2026) describe a 22-month-old girl with persistent bilateral parietal skull defects and global developmental delay. The full text is paywalled. Her computed tomography (CT) showed symmetric ossification defects beside the sagittal suture that the treating physician did not initially recognize. The mother used “a smartphone application powered by Med-Gemini-3D” on a 3D-CT reconstruction. It suggested “Catlin mark skull”, the historical name for enlarged parietal foramina. Genetic evaluation then identified a CDC42BPB variant associated with Chilton-Okur-Chung neurodevelopmental syndrome. The authors state that establishing the diagnosis facilitated earlier therapeutic interventions. The abstract notes that Google introduced Med-Gemini-3D in 2024 and that it is not approved for independent clinical use. A consumer app running Med-Gemini-3D cannot be verified from the abstract.",

The full text is paywalled. Her computed tomography (CT) showed symmetric ossification defects beside the sagittal suture that the treating physician did not initially recognize. The mother used “a smartphone application powered by Med-Gemini-3D” on a 3D-CT reconstruction. It suggested “Catlin mark skull”, the historical name for enlarged parietal foramina. Genetic evaluation then identified a CDC42BPB variant associated with Chilton-Okur-Chung neurodevelopmental syndrome. The authors state that establishing the diagnosis facilitated earlier therapeutic interventions. The abstract notes that Google introduced Med-Gemini-3D in 2024 and that it is not approved for independent clinical use. A consumer app running Med-Gemini-3D cannot be verified from the abstract.",

The mother used “a smartphone application powered by Med-Gemini-3D” on a 3D-CT reconstruction. It suggested “Catlin mark skull”, the historical name for enlarged parietal foramina. Genetic evaluation then identified a CDC42BPB variant associated with Chilton-Okur-Chung neurodevelopmental syndrome.

The mother used “a smartphone application powered by Med-Gemini-3D” on a 3D-CT reconstruction. It suggested “Catlin mark skull”, the historical name for enlarged parietal foramina. Genetic evaluation then identified a CDC42BPB variant associated with Chilton-Okur-Chung neurodevelopmental syndrome. The authors state that establishing the diagnosis facilitated earlier therapeutic interventions. The abstract notes that Google introduced Med-Gemini-3D in 2024 and that it is not approved for independent clinical use. A consumer app running Med-Gemini-3D cannot be verified from the abstract.",
