A case report on thrombosed external jugular vein aneurysm

Venous aneurysms, particularly those involving the external jugular vein, are a rare clinical entity, with the majority of cases being reported in the internal jugular vein. Due to their rarity, there is limited literature regarding their incidence and optimal treatment strategies. This case report discusses a 50-year-old female patient who presented with pain and swelling in the lower left lateral region of the neck, which had persisted for eight days. The patient had previously observed a gradually enlarging mass over the course of eight months. Doppler ultrasound confirmed the presence of a fusiform aneurysm of the external jugular vein, complicated by thrombosis and the absence of flow within the aneurysm sac. Initially, the patient refused the recommended surgical resection and was managed conservatively with anticoagulation therapy using rivaroxaban. However, due to persistent symptoms, the patient eventually consented to surgery, which involved the excision of the aneurysm under local anesthesia. The procedure was uncomplicated, and the patient experienced a favorable recovery with good wound healing.
