Diagnosis With Brief Discussion

Diagnosis
Extranodal marginal zone B cell lymphoma (MALT lymphoma)
Radiologic Findings
Chest radiograph shows multiple nodular lesions in both lower lung fields.
Chest CT also shows multiple ill-defined nodular lesions in both lungs. The lesions show hypermetabolism on FDG-PET CT. Histopathologic examination on the specimens obtained by wedge resection of left upper lobe and left lower lobe revealed extranodal marginal zone B cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma).
Brief Review
Extranodal marginal zone B cell lymphoma, also called low grade B cell lymphoma of mucosa associated lymphoid tissue (MALT), is an extranodal lymphoma that arises in a number of epithelial tissues, including the stomach, salivary gland, lung, small bowel, thyroid, and elsewhere. Extranodal maginal zone B cell lymphoma of the lung is sometimes referred to as bronchial-associated lymphoid tissue (BALT) lymphoma.
The commonest radiological manifestations of pulmonary MALT lymphoma were pulmonary masses or mass-like areas of consolidation and multiple pulmonary nodules. Common features associated with pulmonary MALT lymphoma included air bronchogram, positive angiogram sign on contrast enhanced CT, halo of ground-glass shadowing or peribronchovascular thickening at tumour margins, and discrete patches of ground-glass shadowing. There appears to be no lobar predilection. Slowly progressive pulmonary consolidation in conjunction with a supportive history of autoimmune disease or lymphoma in another mucosal site should strongly suggest the diagnosis of MALT lymphoma, as the radiographic features are not diagnostic in isolation.
