Abstract:
A superior vena cava (SVC) aneurysm is a rare disease that can be confused with upper mediastinal tumor. A 57-year-old female visited our hospital regarding an abnormal shadow in her mediastinum on a chest X-ray. Upon closer examinations, which included three-dimensional computed tomography, we diagnosed it as a SVC aneurysm. Since her SVC aneurysm was regarded as fusiform type at low risk of rupture and thrombosis, she has been managed conservatively and is free from any complications to date. Thus, it is important to keep SVC aneurysms in mind during routine examinations.

Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...
