BALT lymphoma of the lung in a 33-year-old housewife with primary Sjogren's syndrome.. A. Posterior-anterior chest radiograph shows diffuse reticulonodular densities in both lungs.. B. Inspiratory thin-section CT scan shows mosaic pattern of inhomogeneous attenuation. Note the smaller caliber of pulmonary vessels within the area of lower attenuation than within the higher. Note too the presence of bronchial wall thickening in the lingular division of the upper lobe of the left lung.. C. Expiratory thin-section CT scan shows no difference in the extent of mosaic pattern of inhomogeneous attenuation.. D. Light microscopic examination of resected specimen shows diffuse infiltration of marginal zone lymphocytes into peribronchiolar alveolar
space (H and E, x 100).

Chest radiographs demonstrated the presence of bilateral, diffuse, reticulonodular densities in both lungs (Fig. 1A). There was no difference in the extent of mosaic attenuation between inspiratory (Fig. 1B) and expiratory thin-section CT scans (Fig. 1C).
