A rare case report of internal jugular vein aneurysm

Vascular aneurysms are common in the arteries and rare in the veins. Internal jugular vein (IJV) aneurysm is a relatively rare condition. The patient presented with a painless swelling on the right side of the neck that appears while coughing, straining, and bending. Detection of a soft and compressible swelling in the course of IJV, superficial to the sternocleidomastoid muscle, which resolves on compression and becomes prominent on Valsalva maneuver supports the clinical diagnosis of IJV aneurysm. Imaging diagnosis was done by color Doppler ultrasound, and precise delineation of the lesion was done with multidetector computed tomography. There was no thrombus within aneurysm.
