title: Primary pulmonary mucosa-associated lymphoid tissue lymphoma computed tomography findings: a case report.
abstract: Primary pulmonary non-Hodgkin's lymphoma is a very rare neoplasm. It is most frequently represented by the mucosa-associated lymphoid tissue type. We describe a case of a 67-year-old woman who presented with fatigue, mild dyspnea, and consolidation on chest radiograph. The diagnosis of non-Hodgkin's lymphoma was established by transbronchial biopsy, and chemotherapy was then started. The patient was treated with 6 cycles of chemotherapy. She had good response to therapy and no progression of the disease was observed during a 4-year follow-up period. The clinical, radiological and histopathological features are described. This entity has an indolent course, good response to therapy and favorable prognosis. However, despite being an incidental radiological finding in a third of cases, this disease remains highly underdiagnosed.
