Collision tumors at the skull base: unveiling a somatotroph pituitary adenoma coexisting with a petroclival meningioma. Illustrative case
The authors highlight the importance of recognizing the potential for dual pathology in complex intracranial tumors. This case describes the limitations of preoperative imaging in diagnosing collision tumors. Careful long-term surveillance and multidisciplinary management are essential for accurate diagnosis and optimal treatment of collision tumors. https://thejns.org/doi/10.3171/CASE25709.
