DUPLICATION OF INTERNAL JUGULAR VEIN: A RARE VENOUS ANOMALY

Case report: A 2-years-old male presented with severe headache and diagnosed as subarachnoid haemorrhage on plain CT head. CT angiography (CTA) was done on 256slice CT scanner. The arterial phase images showed right MCA bifurcation aneurysm. The venous phase showed variation in the right internal jugular vein anatomy which bifurcated into two channels in lower part of neck (Fig. 1 & 2). They run parallel for a short distance and drain separately into right subclavian vein. Duplicated right IJV was suggested as variation.
