Synchronous multiple meningiomas and renal cell carcinoma metastasis to the brain in a 68Ga-DOTATATE scan: illustrative case

68Ga-DOTATATE is highly sensitive for detecting benign and malignant CNS tumors, including small lesions. It aids in planning treatment, defining radiosurgical targets, and monitoring response. In RCC, it yields a higher SUV than 18F-fluorodeoxyglucose positron emission tomography, making it a more effective diagnostic tool. In meningiomas, the SUV correlates with tumor growth rate. However, specificity is limited, and interpretation requires correlation with MRI, CT, and clinical findings. As its use in CNS tumors grows, understanding its capabilities and limitations is crucial for proper application. https://thejns.org/doi/10.3171/CASE25527.
