Abstract: Objective To assess the value of CT or PET-CT with fluorine-18-labeled fluorodeoxyglucose (FDG) for the diagnosis of pulmonary mucosa-associated lymphoid tissue (MALT) type lymphoma. Methods The CT or FDG PET-CT findings in 14 patients with pathologically proved pulmonary MALT lymphoma were retrospectively analyzed. Results Lung lesions were unilateral in 7 patients and bilateral in 7 patients. Lesions presented as a single mass in 3 patients, as a single consolidation in 3 patients, as a nodule in 1 patient, as multiple nodules in 1 patient, as multiple patchy consolidations in 4 patients, as a mass with multiple nodules and patchy consolidations in 1 patients, as diffuse interstitial change in 1 patients. Air bronchogram was found in 9 patients and CT angiogram sign in 5 patients. On PET-CT, lesions showed heterogeneous FDG uptake in 2 patients, maximum standard uptake value was higher than 2. 5. Conclusion Imaging characteristics of pulmonary MALT lymphoma are single or multiple nodules or consolidations with air bronchogram on CT, and heterogeneous high FDG uptake on PET-CT.
