Chest High-resolution Computed Tomography Findings in 601 Patients with Inflammatory Bowel Diseases.

Rationale And Objectives: Pulmonary involvement in inflammatory bowel disease may reflect the common embryonic origin of the gastrointestinal tract and the bronchial tree. No studies have compared pulmonary high-resolution computed tomography (HRCT) findings between ulcerative colitis (UC) and Crohn disease (CD). This study aimed to assess the relationship between pulmonary HRCT findings and inflammatory bowel disease activity and to compare HRCT findings between UC and CD.

Computed tomography findings in Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) of the elderly: comparison with EBV-negative DLBCL.

Objective: This study aimed to compare CT findings in patients with Epstein-Barr virus positive (EBV+) diffuse large B-cell lymphoma (DLBCL) of the elderly with CT findings in patients with Epstein-Barr virus negative (EBV-) DLBCL.

Methods: We retrospectively identified 9 consecutive patients with EBV+ DLBCL (6 males and 3 females; aged 72-83 years, mean: 76.2 years) and 39 consecutive patients with EBV- DLBCL (19 males and 20 females; aged 53-91 years, mean: 71.

Chest HRCT findings in acute transformation of adult T-cell lymphoma/leukemia.

Objectives: To assess chest high-resolution computed tomography (HRCT) findings in patients with acute transformation of adult T cell leukaemia/lymphoma (ATLL).

Methods: We retrospectively identified 72 consecutive patients at our institution with ATLL between October 2000 and March 2014. The cases included acute type (n = 20), lymphoma type (n = 21), smouldering type (n = 24) and chronic type (n = 7).

EBV-positive MTX-diffuse large B cell lymphoma in a rheumatoid arthritis patient.

Methotrexate (MTX)-associated lymphoproliferative disorders have received much attention from rheumatologists, and early diagnosis is very important for reducing mortality. There are several reports of radiologic findings in patients with pulmonary malignant lymphoma, mainly consisting of masses, nodules, and lymphadenopathy. Computed tomography has rarely detected necrosis in the masses.
