title: Retromandibular vein diverticulum: unique imaging findings with a novel therapeutic strategy.
abstract: Diverticula of the vascular system are rare. A diverticulum involving the retromandibular vein has not been described to date. We describe the imaging findings and a novel therapeutic strategy for the management of this rare diverticulum. A 25-year-old male presented with complaints of swelling behind the angle of mandible that enlarged on straining. On imaging, a retromandibular vein diverticulum was seen. The diverticulum was punctured percutaneously with the patient performing Valsalva maneuver and injected with sclerosant microfoam. There was no sclerosant reflux into the normal neck veins. At 6-month follow-up, the patient had complete resolution of his symptoms. We also have done a review of literature for patients with venous diverticula in the head and neck region treated by endovascular techniques.
