8>A 30-year-old otherwise healthy woman presents to her physician
with complaints of fatigue and dyspnea. Physical examination reveals
normal breath sounds and the presence of third and fourth heart sounds.
Chest x-ray shows clear lung fields but right ventricular enlargement,
main pulmonary artery enlargement, and "pruning" of the peripheral
vasculature. Electrocardiogram shows right axis deviation and right
ventricular hypertrophy. Left ventricular function appears normal
on echocardiography. Serologic studies show antinuclear antibodies.
Which of the following pathological findings would this patient
also show, either at autopsy or if an appropriate biopsy was taken?
A. Mural thrombus of the right atrium
B. Necrosis and scarring of the left ventricle
C. Plexogenic pulmonary vasculopathy
D. Pulmonary artery stenosis
E. Severe pulmonary fibrosis

E. Severe pulmonary fibrosis due to SLE.

clear lung fields..wont fibrosis produce abnormal lung fields?

[ArchivalUser]

plexogenic pulmonary vasculopathy or PPHt

[ArchivalUser]

correct chintoo.Its pulmonary HTN primary type.The pulmonary vasclature is dilated and plexogenic.

[ArchivalUser]

folks, the answer is A.

[ArchivalUser]

how can u explain pulmonary main vessel dilation on this basis?

[ArchivalUser]

simply an emblus is lodged in a big branch of the pulmonary artery, which can lead to vessel dilation

[ArchivalUser]

the answer with me is pulmonary HTN.They say inlike cardiac tempnade,cardiac arrythmias from mural thrombus is uncommon in idiopathic pulmonary HTN.
