Epstein-Barr virus-positive diffuse large B-cell lymphoma with human immunodeficiency virus mimicking complicated frontal sinusitis: A case report

Figure 1 A 46-year-old male presented with the right forehead pain. A and B: Axial contrast enhanced paranasal sinus computed tomography (CT) shows fluid-like opacification in both frontal sinuses with combined soft tissue lesion in the right forehead and medial portion of the right orbit. There is mild marginal enhancement around the soft tissue lesion without enhancing solid component; C: There is no definite bone erosion in the anterior wall of the right frontal sinus; D: F-18 fluorodeoxyglucose (FDG) positron emission tomography/CT shows irregularly increased FDG uptake with maximum standardized uptake value of 14.4 g/mL in the marginal portion of the right forehead lesion which corresponds to marginal enhancement on paranasal CT.
