Diagnosis With Brief Discussion

Diagnosis
MALT lymphoma
Radiologic Findings
Chest CT demonstrated an anterior mediastinal mass having focal low attenuation. On lung window settings, there were multiple thin-walled cysts in both lungs. In addition, a few solid nodules were shown in RML and RLL. A nodule in the RML contained calcification. The lesions were hypermetabolic on PET/CT scan. The patient underwent total thymectomy and wedge resection for multiple nodules in both lungs. The pathologic diagnosis of anterior mediastinal mass was thymic extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) with extensive plasma cell differentiation. Lung nodules were confirmed as lung involvement of thymic extranodal marginal zone B-cell lymphoma and amyloid deposit.
