[Imaging of pulmonary artery involvement in Takayasu disease]

Abstract

Objectives: Illustrate imaging aspects of pulmonary artery involvement in Takayasu's arteritis.

Patients and methods: Retrospective study of six patients among 28 patients with Takayasu arteritis whose disease involved the pulmonary arteries and to review their clinical and computed tomography data.

Results: Mean patient age among those with pulmonary artery involvement was 34 years. All patients exhibited extensive lesions of systemic arteries. The most common computed tomography angiography sign was wall thickening. Dilatation of the pulmonary artery trunk was observed in one-third of cases.

Conclusion: Pulmonary arterial involvement in Takayasu's disease is not uncommon. Computed tomography is a reliable imaging technique to establish the diagnosis.
