18F-FDG PET/CT images in a child with cutaneous B cell Lymphoblastic Lymphoma presented with bone involvement

B-cell lymphoblastic lymphoma (B-LBL) is an uncommon subtype of pediatric non-Hodgkin Lymphoma (NHL) which rarely involves the skin primarily. The positron emission tomography with 2-deoxy-2-[fluorine- 18] fluoro-D: -glucose integrated with computed tomography (18F-FDG PET/CT) scan findings of a 8-year-old boy with cutaneous B-LBL were presented. PET/CT scan demonstrated mild FDG uptake in the lesion located on the scalp and also multiple bone metastases with increased FDG uptakes in several areas. The importance of 18F-FDG PET/CT scan in primary staging of the patients with primary cutaneous B-LBL. due to its impact on planning of therapy via the determination of unexpected malign infiltration sites was emphasized.
