Nineteen-year-old female with idiopathic thrombosis of the internal jugular vein.

Internal jugular vein thrombosis is a rarely seen condition which may be due to infection or neoplastic, thrombophilic, traumatic or iatrogenic causes. If the thrombosis in the jugular vein leads to pulmonary embolism, septic emboli or atrial or dural sinus thrombosis, it may be life-threatening. We report a successfully treated case of a 19-year-old female patient presenting with swelling and neck pain who was diagnosed with a stepwise approach of this rare condition.
