Summary
Behcet
Area of Science:
- Radiology and cardiovascular imaging
- Thoracic imaging
- Rheumatology and immunology
Background:
- Behcet's disease (BD) is a multisystemic inflammatory disorder.
- Chest imaging is crucial for diagnosing and monitoring BD complications.
Purpose of the Study:
- To determine the range and frequency of abnormal chest findings on multidetector computed tomography (MDCT) in patients with Behcet's disease.
- To identify key imaging features indicative of BD involvement.
Main Methods:
- Retrospective review of chest MDCT scans from 44 patients diagnosed with Behcet's disease between 2009 and 2016.
- Analysis of abnormalities in the pulmonary artery, lungs, heart, mediastinum, pleura, and pericardium.
Main Results:
- Sixteen patients (36.4%) exhibited BD-related CT findings.
- Pulmonary artery (PA) involvement was most frequent (27.2%), including thrombosis and aneurysms.
- Enlarged PA diameter (mean 29 ± 3.7 mm) and hypertrophied bronchial arteries were common.
- Lung parenchymal findings were often associated with PA involvement.
- Cardiac filling defects were observed in 75% of patients with PA aneurysms.
Conclusions:
- Behcet's disease involves multiple anatomical sites, as seen on chest MDCT.
- Pulmonary artery enlargement and hypertrophied bronchial arteries are significant indicators of PA involvement in BD.
- Screening for cardiac filling defects is recommended in BD patients with PA aneurysms.
