Diagnosis With Brief Discussion

Diagnosis
Extranodal marginal zone B cell lymphoma (MALT lymphoma)
Radiologic Findings
A month ago, chest PA shows a nodular increased opacity in right lower lung field. Follow-up chest CT scan shows a patchy nodular consolidation and satellite micronodules with perilymphatic distribution due to thickening of peripheral interstitum in right lower lobe without significant inverval change. Enhanced chest CT shows a relatively homogeneously enhancing nodular consolidation with air-bronchogram. This lesion shows hypermetabolism (max 6.9) on follow up FDG-PET CT. Transbronchial lung biopsy shows nonspecific chronic inflammation with infiltration of lymphocyte. Histopathology after surgical resection reveals extranodal marginal zone B cell lymphoma.
Brief Review
