The chest radiographs (n = 18) and CT scans (n = 17) of 24 patients (18 men and 6 women) aged 27-78 years (mean = 56 years), with a known diagnosis of pulmonary MALT lymphoma, were retrospectively reviewed by two radiologists and the imaging findings are described. There were multiple other cavitating and non-cavitating pulmonary nodules, and extensive mediastinal lymphadenopathy. Background: Primary pulmonary lymphoma (PPL) mainly comprises mucosa-associated lymphoid tissue (MALT) lymphoma as well as other subtypes of lymphoma. An Algorithmic Approach to the Interpretation of Diffuse Lung Disease on Chest CT Imaging. Pulmonary Intravascular Large B-cell Lymphoma in a Patient Administered Methotrexate for Rheumatoid Arthritis. A primary pulmonary lymphoma is defined as an extranodal pulmonary lymphoma without evidence of extrapulmonary involvement at diagnosis and during the subsequent three months. Though there are definite advantages to this, they are at times offset by diagnostic pitfalls especially in entities with elusive clinical presentation.Peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS) is an aggressive subtype of T-cell lymphomas that . Magnetic resonance imaging (MRI). along subpleural surface and fissures, along interlobular septa and the peribronchovascular bundle). The primary pulmonary lymphoma (PPL), with a low incidence, was highly misdiagnosed in clinic. .

The differential diagnosis of LC includes sarcoidosis and other chronic interstitial lung diseases such as silicosis, coal worker's pneumoconiosis, extrinsic allergic alveolitis (hypersensitivity pneumonitis), and cryptogenic fibrosing alveolitis, as well as other neoplasms, such as lymphoma and Kaposi sarcoma.Most of these diagnoses can be excluded on the basis of the clinical findings alone. De Schepper AM. After participating in this educational activity, the . Pulmonary lymphoma is involved in < 10% of Hodgkin lymphomas and < 5% of non-Hodgkin lymphomas. Primary pulmonary lymphoma (PPL) is defined as clonal lymphoid proliferation involving lung parenchyma and/or bronchi without detectable extra pulmonary lymphoma at primary diagnosis or the subsequent 3 months ().PPL is a rare neoplasm, accounting for ≤1% of all lymphomas and 0.5-1% of primary pulmonary malignancies ().The most common type of PPL is mucosa-associated lymphoid . CT Imaging of Primary Pulmonary Lymphoma. . Primary pulmonary lymphoma is a very rare entity and is thought to represent only 3-4% of extranodal non-Hodgkin lymphoma, <1% of all non-Hodgkin lymphoma, and 0.5-1% of all primary pulmonary malignancies 1-6. Primary pulmonary Hodgkin's lymphoma is an uncommon initial presentation; lung lesions usually occur later in the course of the disease. Acquired pulmonary stenosis in adults is rare and is usually caused by extrinsic compression from a mediastinal tumour. The interpretation of interstitial lung diseases is based on the type of involvement of the secondary lobule. No history of other malignancy within last 5 years except for early skin cancer. This patient had a chronic disease with progressive consolidation. No prior treatment with chemo- or radiotherapy. Primary pulmonary B-cell lymphomas (PP-BCLs) comprise a group of extranodal non-Hodgkin lymphomas of B-cell origin, which primarily affect the lung without evidence of extrapulmonary disease at the time of diagnosis and up to 3 months afterwards. 14 January 2020 | Respirology Case Reports, Vol. Lymphoma of Lung may be associated with autoimmune disorders and bacterial infection.
