Diagnosis With Brief Discussion
- Diagnosis
- Non-Hodgkins Lymphoma manifesting Golden S sign
- Radiologic Findings
- The chest radiograph showed a right hilar bulging shadow and collapse of right upper lobe, which is known as so-called Golden S sign. Chest CT scan showed the collapse of the right upper lobe and multiple lymph nodes enlargement at right hilar area and mediastinum. The conglomerated lymph nodes at the right hilar area compressed and obstructed the right upper lobar bronchus. The lesion encased and splayed out the pulmonary vessels in the right upper lobe with mucoid impaction within the collapsed lobe.
Lymph node biopsy at the left supraclavicular fossa revealed a diffuse large B cell lymphoma with morphologic features of T-cell rich B-cell lymphoma. Immunohistochemical staining demonstrates the scattered large cells are B-cells expressing L26/CD79a (second figure as belows). Ki-1, ALK, CD10, TIA/granzyme B, CD23 and CD23 are expressed in the large cells. And the patient was in partial remission two months later after chemotherapy.
- Brief Review
- Golden S sign on chest radiograph has been known to be a typical sign of bronchogenic carcinomas. However, malignant lymphomas occasionally involve airway resulting in lobar or segmental collapse. Lung or airway involvement in patients with non-Hodgkins lymphoma and Hodgkins disease is unusual at the onset of the disease. Even if a malignant lymphoma shows Golden S sign on chest radiograph, like our case, the recognition of the CT findings such as the tumor infiltration encasing and splaying out the pulmonary vessels in the collapsed lung and associated multiple lymph nodes enlargement could be clues for differentiating thoracic lymphoma from bronchogenic carcinoma.
