External jugular vein spontaneous aneurysm, diagnosis and treatment with video

True and false aneurysms of veins are very rare conditions and only few cases have been described in the literature. We present a case of a 56-year-old female with personal history of primary arterial hypertension and connective tissue disease. Ultrasound of the neck showed a saccular, compressible, hypoechoic structure that appeared to have a direct communication with the left external jugular vein lumen. The venous aneurysm was removed and the histopathology of the mass showed a grossly dilated vein, with continuous aspects of the entire 3 layer of the venous wall, classifying it as a venous aneurysm.
