【Abstract】 Objective To study the imaging manifestations of primary pulmonary non Hodgkin’s lymphoma (PPNHL).Materials and Methods Imaging features, including plain chest film (n=7), CT (n=5) and MRI (n=2), and pathologic findings in 7 patients with pathologically proved PPNHL were retrospectively analyzed. Related references were reviewed.Results Of 7 cases, solitary pulmonary mass was seen in 5, in 3 of which the lesion had indistinct border and presented as ground glass shadow, and in 4 of which the lesion was lobulated. For the remaining 2cases, pneumonia shadow and segmental consolidation was seen in one each. On MRI of 2 cases, the lesions were iso signal on T 1WI and iso or high signal on T 2WI. Pathologically, B lymphocyte type was seen in 3, T lymphocyte type in 2 and not typed in 2 cases.Conclusion PPNHL is a rare disease. Clinically, it has no specific features. Solitary pulmonary lobulated mass with blurred border and ground glass shadow is a relatively characteristic imaging finding, nevertheless, it is depended on pathologic examination to establish the diagnosis.更多还原
