Abstract:
We present the case of a 9-month-old preterm male infant admitted to neonatal intensive care unit (NICU) in whom extensive calcified thrombosis of the inferior vena cava (IVC) and left renal vein was incidentally detected via x-ray (XR). The diagnosis was subsequently confirmed by ultrasound (US) and computed tomography (CT). Initial imaging via radiography revealed lace-like abdominal calcification. Subsequent computed tomography (CT) demonstrated dense calcification extending from the inferior vena cava (IVC) into the distal left renal vein, as well as the bilateral common iliac veins, the right external iliac vein, and the left internal iliac vein. Extensive collateral circulation was also observed, consistent with chronic venous occlusion.

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 middle...
