FDG PET/CT findings in 3 cases of pulmonary peripheral T-cell lymphoma

Pulmonary involvement of peripheral T-cell lymphoma is rare. It is difficult to make a clinical and radiologic diagnosis of pulmonary lymphomatous involvement, yet the diagnosis is often critical in determining treatment. We present 3 cases of pulmonary peripheral T-cell lymphoma with FDG PET/CT findings. In these 3 cases, FDG PET/CT images revealed multiple bilateral FDG-avid nodules, masses, or mass-like consolidations with or without air bronchogram. Familiarity with these imaging features may be helpful for the diagnosis and differential diagnosis.
