An unusual presentation of acute pulmonary embolism secondary to upper extremity deep vein thrombosis

Abstract

Acute pulmonary embolism (PE) secondary to congenital venous malformation of the upper limb is a rare clinical entity. Clinical manifestation may range from vague shoulder discomfort to features of superior vena cava or thoracic outlet syndrome. We report a case of a 43-year-old adult patient who was referred as acute coronary syndrome and on evaluation was diagnosed as acute PE secondary to upper extremity deep vein thrombosis. Magnetic resonance venogram of the right upper limb revealed congenital venous malformation with thrombus as the cause for deep vein thrombosis.
