Lymphoblastic Involvement of the Bone Marrow as a Cause of Superscan Appearance in F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography.

The F-fluorodeoxylucose (FDG) positron emission tomography (PET) is the gold standard imaging modality in the staging of lymphoma. The superscan appearance in the FDG PET/computerized tomography (CT) imaging might be because of benign diseases or malignant infiltrations. This case report presents lymphomatous blastic infiltration as a cause of superscan appearance in F-FDG PET/CT.
