CTICasesPrimary pulmonary marginal zone B-cell lymphoma of MALT
Imaging findings
Serial chest CT scans show progressive development and enlargement of bilateral, poorly defined, airway-associated ground-glass and solid nodules. Histopathology from biopsy confirmed mucosa-associated lymphoid tissue lymphoma.
Key takeaways
MALT lymphoma is the most common primary pulmonary lymphoma. It typically presents as slowly progressive, indolent, airway-centric ground-glass or solid nodules or consolidations along lymphatic pathways. It is often a low-grade malignancy that has an indolent course and may be managed conservatively or with chemotherapy if symptomatic.
