Abstract:
The vast variability of the overall rare congenital anomalies of the inferior vena cava (IVC) are mostly detected by accident through different imaging modalities. These cannot be classed as pathological findings, and should not be confused with lymphomas and has to differ from secondary collateral venous pathways. Based on 656 CT examinations 10.5% known forms of IVC anomalies were found. According to the embryological development three main groups of IVC variants could be nosologically classified: agenesis of the suprarenal IVC, anomalies of the pars renalis and anomalies of the infrarenal IVC. Additionally three unusual anomaly complexes were found. For the understanding details of the embryology based on a simplified depiction are presented.

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...
Veins of the Abdomen and Pelvis
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...
Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
