Concurrent Intracranial and Spinal Dural Metastases Demonstrated by 68Ga-DOTATATE PET/CT With Negative 123I-MIBG SPECT/CT in a Pediatric Neuroblastoma Patient

Abstract Contrast enhancement MRI of the brain and spine showed abnormal enhancement in intracranial and spinal dural lesions in a 6-year-old boy with high-risk neuroblastoma, suggesting the possibility of dural metastases. 123 I-MIBG SPECT/CT did not show any abnormal MIBG accumulation in these lesions. However, 68 Ga-DOTATATE PET/CT showed obvious DOTATATE uptake in these metastatic lesions. Surgical pathology confirmed the diagnosis of intracranial dural metastasis. Concurrent intracranial and spinal dural metastases from neuroblastoma demonstrated by 68 Ga-DOTATATE PET/CT with negative 123 I-MIBG SPECT/CT have not been reported previously.
