Acute right-sided pleuritic pain and breathlessness. High D-dimer.

Patient Data

Age: 50 years
Gender: Female

Severe luminal narrowing (maximal 4 mm caliber) of the right main pulmonary artery, due to severe concentric mural thickening, such that only a thin trickle of contrast passes through.

Mild mural thickening of the distal ascending aorta and aortic arch. Marked mural thickening of the brachiocephalic trunk, right subclavian and bilateral common carotid arteries. Non-opacified left subclavian artery.

Case Discussion

Appearances are consistent with a large vessel vasculitis, and this patient had had a biopsy performed elsewhere confirming Takayasu arteritis.
