A new lower limb venous duplex scan and Multislice CT scan of the pulmonary arteries revealed Subacute bilateral DVT with similar findings in the CT pulmonary angiography Which stated the existence of thrombotic filling defects that involved the main right pulmonary artery, extending partially into the segmental lower lobe artery branches with adjacent ectatic bronchial arteries (Fig. 1), also with a smaller thrombotic circumferential filling defect at the left lower lobe artery branch, preserving a centrally patent residual lumen (Fig. 2).

Unfortunately, such findings of suspicious pulmonary aneurysms with thrombotic process inside as well as dilated ectatic bronchial arteries could not be correlated at the time of presentation to Hughes Stovin syndrome (see Fig. 3).
