Solitary Dural Metastasis From Neuroblastoma Detected by 123I-MIBG SPECT/CT

ABSTRACT: 123 I-MIBG SPECT/CT was performed for follow-up in an asymptomatic 8-year-old girl with a history of neuroblastoma. The images showed an unsuspected abnormal accumulation in the head, which was identified as a hyperdense lesion of the dura with increasing MIBG uptake, suggesting the possibility of metastasis from neuroblastoma. A brain MRI with contrast showed a remarkably enhanced lesion beside the confluence of sinuses, which mimicked meningioma. Results of the surgical pathology are consistent with the diagnosis of dural metastasis from neuroblastoma.
