Background: Multidetector computed tomographic (MDCT) angiography is considered the
best modalityforthethree-dimensional delineation of the Inferior Vena Cava (IVC).
Knowledge of the broad spectrum of congenital anomalies and pathologic conditions
affecting the inferior vena cava (IVC) is important.
Aim of the Study: To assess the role of MDCT angiography with multiplanar reformation
(MPR) and three-dimensional (3D) reconstruction in the delineationofinferior vena cava
anomalies and abnormalities.
Method: The study was done in the period from April 2019 to March 2020in Zagazig
university hospitals. Thirty patients were included (70% males and 30% females; age range:
20-55 years), who had MDCT angiography using a 128-slice MDCT scanner (Ingenuity
Phillips health care, best Netherlands).
Results: In our study, IVC thrombosis was the most commonly detected abnormality in 17
patients (56.6%), followed by Budd-Chiari syndrome in 5 cases (16.6%) then three cases
(10%) with heterotaxy syndrome, only one case (3.3%) with double IVC and another one
(3.3%) with left-sided IVC. Regarding 17 patients found with IVC thrombus, 5 cases (29.5%)
with bland thrombus were detected, while 12 cases (70.5%) with tumor thrombus extension
were detected. IVC tumor thrombus in 12 patients were distributed as follow; Among 12
patients examined with tumor thrombus, the most commonly detected type extended from
HCC presented in 7 cases (58.3%), followed by RCC in 3 cases (25%), then one case with
pancreatic mass and one case with ovarian mass with the percentage of 8.3% for each.
