Fig. 4. ¹⁸FDG PET-CT and diagnostic contrast-enhanced chest CT in patient with angioimmunoblastic T-cell lymphoma.

MIP image (A) demonstrates intense ¹⁸FDG uptake in cervical, thoracic, abdominal, and left inguinal lymph node stations, subcutaneous nodules, and bilateral pulmonary nodules, masses, and consolidations. Focal ¹⁸FDG uptakes in left arm are likely related to injection. Axial fused PET-CT image (B) demonstrates intense ¹⁸FDG uptake right axillary lymphadenopathy (arrow) and within bilateral pulmonary nodules and masses. Axial contrast-enhanced CT image on lung window (C) demonstrates pulmonary nodules and masses with surrounding groundglass opacities and mild intralobular septal thickening. One of lung masses was biopsied, and proven to be angioimmunoblastic lymphoma. Patient had complete response after treatment with CHOP and underwent autologous stem cell transplant but developed myelodysplastic syndrome and T-cell lymphoma recurrence and expired. FDG = flourodeoxyglucose, MIP = maximum intensity projection, PET = positron emission tomography
