Mf. Bozkurt et al., Ventilation-perfusion lung scan and helical computed tomographic findings in a patient with Behcet's disease, CLIN NUCL M, 26(8), 2001, pp. 721-722
Behcet's disease is a chronic multisystem vasculitis of undetermined origin
. The aorta, vena cava, and pulmonary arteries are affected in approximatel
y 25% of patients. The major diagnostic criteria for Behcet's disease are o
rogenital ulceration, erythema nodosum, thrombophlebitis and ocular lesions
. Pulmonary involvement in Behcet's disease is unusual and it is encountere
d in only approximately 5% of patients. Recurrent episodes of dyspnea, coug
h, chest pain, hemoptysis, and fever are cardinal symptoms of pulmonary inv
olvement. Multiple segmental and subsegmental perfusion defects with mismat
ched ventilation scan findings can show pulmonary involvement of Behcet's d
isease and pulmonary thromboembolism. Helical computed tomography (CT) can
provide better anatomic details of vascular and parenchymal structures and
can help to reveal the causes of perfusion defects. The authors describe a
patient with Behcet's disease in whom ventilation-perfusion imaging and hel
ical CT findings revealed pulmonary involvement.
