A 4-year-old girl with bone metastasis from right adrenal neuroblastoma. (A) Sagittal MRI showing a large, heterogeneous mass in the right adrenal gland, indicated by the red arrow. (B) Sagittal MRI showing multiple vertebral lesions with low itensities, marked by red asterisks (T7, T9 and T11). These lesions show altered signal intensity compared to normal vertebral marrow, indicating metastatic involvement. (C) F-18 FDG Whole Body PET Scan: The areas of increased uptake correspond to sites of active tumor growth, including the primary adrenal mass, spine, and possibly other distant organs such as the liver or lymph nodes. The overall pattern of distribution suggests extensive dissemination of neuroblastoma cells. (D) Axial MRI at the T12 level showing a metastatic spread of neuroblastoma mass in the left epidural space (yellow arrow), leading to neurological symptoms such as pain, weakness and sensory deficits.
