Spectrum of the inferior vena cava: MDCT findings.

Inferior vena cava (IVC) abnormalities are not uncommon. Congential anomalies, thrombosis, neoplasms, and obstructive lesions can involve IVC. With the wide use of multidetector CT, it has demonstrated its ability to display the abnormalities of IVC. Congenital anomalies, thrombosis, neoplasms, and stenosis or obstructive diseases and other abnormalities can be demonstrated by MDCT. We present a pictorial essay to illustrate its roles in detecting and defining the nature of lesions of IVC, from the anatomy to disease spectrum of IVC.
