TL;DR: BALT lymphomas usually appear as airspace consolidation or nodules with air bronchogram or adjacent ground-glass attenuation at CT, similar to previous descriptions of pseudolymphomas.

Abstract: Purpose The purpose of this work was to describe the CT findings of pathologically confirmed bronchus-associated lymphoid tissue (BALT) lymphoma in 10 patients. Method The CT examinations of 10 patients with pathologically proven BALT lymphoma were reviewed retrospectively by two radiologists. Evaluated findings included number and distribution of lesions. We also assessed other CT findings such as presence of airspace consolidation, nodules, ground-glass attenuation, bubble-like radiolucencies, air bronchogram, bronchial dilatation, and lymphadenopathy. Results Pulmonary lesions were revealed as airspace consolidation in six patients (60%) and nodule(s) in six (60%). Multiplicity of disease was seen in seven patients (70%) and bilateral lung lesions in six (60%). Areas of ground-glass attenuation were seen in seven patients (70%). Bubble-like radiolucencies were present in five patients (50%) and air bronchogram in nine (90%). Findings of bronchial dilatation and lymphadenopathy were seen in three patients (30%). Conclusion BALT lymphomas usually appear as airspace consolidation or nodules with air bronchogram or adjacent ground-glass attenuation at CT. These findings are similar to previous descriptions of pseudolymphomas. Multiple bilateral lesions are common in BALT lymphoma. Bubble-like radiolucencies have not been described previously and can be an additional finding of BALT lymphoma.

Primary pulmonary lymphoma
TL;DR: In this article, the authors describe the pathophysiological, diagnostic, prognostic, and therapeutic aspects of primary pulmonary B-cell lymphoma, including pathophysiology, diagnosis, prognosis, and treatment.

Marginal zone B-cell lymphoma of bronchus-associated lymphoid tissue: imaging findings in 21 patients.
Young A Bae,Kyung Soo Lee,Joungho Han,Young-Hyeh Ko,Byung-Tae Kim,Myung Jin Chung,Taesung Kim +6 more
TL;DR: Marginal zone B-cell lymphomas of BALT manifest diverse patterns of lung abnormality on CT scans, but single or multiple nodules or areas of consolidation are the main patterns that occur in a majority (76%) of patients.

Unusual primary lung tumors: a radiologic-pathologic overview.
TL;DR: Although unusual primary lung tumors are difficult to diagnose on the basis of imaging findings alone, cross-sectional imaging can play an important role in the diagnostic work-up of these unusual tumors by delineating their extent and directing the radiologist or bronchoscopist to the appropriate biopsy site.

Pulmonary mucosa-associated lymphoid tissue lymphoma revisited
Raphael Borie,Marie Wislez,Martine Antoine,Christiane Copie-Bergman,Catherine Thieblemont,Jacques Cadranel +5 more
TL;DR: The pathophysiology includes cytogenetic abnormalities and autoimmune diseases, whereas an association with a chronic pulmonary infection is still suspected but not yet demonstrated and the current available treatments are discussed in this review.

CT Findings of Thoracic Manifestations of Primary Sjögren Syndrome: Radiologic-Pathologic Correlation
Ryoko Egashira,Tetsuya Kondo,Tetsuyoshi Hirai,Noriyuki Kamochi,Mai Yakushiji,Fumio Yamasaki,Hiroyuki Irie +6 more
TL;DR: Air cysts and mediastinal manifestations may help diagnose primary Sjögren syndrome, and MALT lymphoma should always be considered because its morphologic characteristics are similar to those of benign lymphoproliferative disorders.

Solitary pulmonary nodule: high-resolution CT and radiologic-pathologic correlation.
TL;DR: Edge and internal characteristics of pulmonary nodules evaluated with high-resolution computed tomography were correlated with the pathologic specimens in 93 patients, and malignant nodules as a group were larger than benign lesions and more commonly demonstrated a spiculated contour, lobulation, and inhomogeneous attenuation.

Primary lymphomas of the lung morphological immunohistochemical and clinical features
TL;DR: The prognosis of the B‐cell‐derived lung lymphomas without constitutional symptoms was relatively favourable, regardless of whether they were of low‐ or high‐grade malignancy, whereas patients with constitutional symptoms and the two patients with T‐cell lymphomas showed a bad prognosis.

Benign lymphoid disorders of the lung, with a theory regarding their development.

TL;DR: It is suggested that lymphoid hyperplasia is a basic inflammatory response of the lung and not malignant lymphoma, which is a basis for understanding these disorders.

Primary pulmonary non-Hodgkin's lymphomas
TL;DR: Clinical data suggest that limited surgery or non‐aggressive chemotherapy can provide long‐term survival in patients with such slowly developing neoplasms, however, non‐invasive diagnostic methods need to be developed.
