What are the CT and FDG-PET/CT imaging characteristics of pulmonary MALT lymphoma and their utility in patient follow-up?
CT and FDG-PET/CT imaging of pulmonary MALT lymphoma typically reveal multiple, bilateral consolidations or nodules with increased FDG uptake, which are valuable for diagnosis and monitoring treatment response.
May aid pattern recognition on CT/PET-CT in suspected pulmonary MALT lymphoma; leaves open prospective validation for diagnostic and monitoring utility.
PURPOSE: The aim of the study was to present the computed tomography (CT) and fluorine 18 (F) fluorodeoxyglucose-positron emission tomography (FDG-PET)/CT imaging findings of pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma and evaluate their roles in the follow-up of this tumor. METHODS: Computed tomography and FDG-PET/CT imaging findings of 18 cases of pathologically proven pulmonary MALT lymphoma were reviewed retrospectively. RESULTS: Multiple and solitary lesions were detected in 15 and 3 patients, respectively. Of those patients with multiple pulmonary lesions, 12 were bilateral, and 3 were unilateral. A total of 51 pulmonary lesions were identified in 18 patients, which included lesions with consolidation (31/51), mass and nodule (12/51), and ground-glass attenuation (8/51). F fluorodeoxyglucose-PET/CT imaging (n = 8) revealed increased FDG uptake in all lesions in 8 cases. At follow-up, 3 patients experienced complete remission, 10 had partial remission, and 2 remained stable. CONCLUSIONS: Computed tomography and FDG-PET/CT images of the pulmonary MALT lymphoma usually reveal multiple, bilateral consolidations, masses, or nodules with air bronchogram and increased FDG uptake. Computed tomography and FDG-PET/CT imaging play important roles in the diagnosis and follow-up of patients with pulmonary MALT lymphoma.

Zhang et al. (2011) conducted an observational in Pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma (n=18). Computed tomography (CT) and FDG-PET/CT imaging was evaluated on Imaging findings (lesion characteristics and FDG uptake). Computed tomography and FDG-PET/CT imaging of pulmonary MALT lymphoma identified 51 lesions in 18 patients, predominantly presenting as consolidations (31/51) or masses and nodules (12/51).
