Conclusion
Absence of the inferior vena cava is one of the rarest anomalies of the venous system.
It is so uncommon that when not clinically manifested it could be a challenge for the radiologist.
It should be considered in patients,
especially young people,
presenting with venous flow abnormalities.
CECT or MRI are essential for the diagnosis,
being able to not only show the absence of the IVC but also assess the related abnormalities – usually collateral pathways and deep venous thrombosis (DVT).
Venography is a very accurate but invasive imaging method.
US is a very useful tool and is sometimes where it all starts – with the diagnosis of DVT.
It is important to be distinguished from other causes for occlusion of the IVC like chronic thrombosis or compression.
A correct radiological diagnosis is essential and would give the clinicians awareness of the condition and the possible complications and possibilities for treatment.
