Primary Fusiform Superior Vena Cava Aneurysm

Abstract

Superior vena cava (SVC) aneurysms are rare mediastinal vascular lesions. We report a case of a 42-year-old female, who presented to the outpatient department with features suggestive of lower respiratory tract infection. Chest X-ray showed abnormal contour and widening of right border of mediastinum. Computed tomography (CT) thorax revealed fusiform aneurysmal ectasia of SVC measuring 4.5 × 5.5 × 8.9 cm without internal thrombosis or dissecting flap. Management options include observation with follow-up and in some cases anticoagulation and surgical excision may be considered. The general consensus is that fusiform variety can be managed conservatively in view of the low risk of complications. The saccular aneurysms may need to be managed with anticoagulation therapy or surgically in view of the possible risk for thrombus formation and pulmonary embolism. Since in our case it was an asymptomatic primary fusiform SVC aneurysm, patient was advised for conservative management and follow-up.

“…Superior vena cava and azygos vein aneurysms are an extremely rare phenomenons, as fewer than 40 cases have been reported in the indexed English literature. 1 Detailed diagnostics include chest computer tomography or magnet resonance imaging with angiography are necessary. The more common fusiform aneurysms are usually detected incidentally, portend a benign prognosis, and are managed conservatively.…”

Spontaneus rupture of the left venous angle aneurysm - a case report

“…Sometimes aneurysms occur spontaneously, of unclear cause, as in our case. Venous aneurysms in the region of the neck and upper extremities are rare, and only a few cases have been described in the literature [6][7][8].…”

“…The complications are rare, and only a few cases with complications, including rupture or pulmonary thromboembolism, have been reported in the literature [6][7][8].…”
