Lymphangiomatous Tumors of the Neck: Tips to Avoid Iatrogenic Nerve Injuries in the Brachial Plexus Region

Lymphangiomas are rare malformations of the lymphatic system and can often be found in the neck region, where its proximity to the brachial plexus may cause compressive neuropathy and possible iatrogenic injuries during dissection. We report 4 cases of lymphangiomas with compression of the brachial plexus that were successfully removed without permanent nerve injuries and present a literature review of the preoperative approach and surgical techniques. A preoperative multidisciplinary approach can help surgeons predict what they may encounter during the surgery. A careful and stepwise dissection of the vital structures surrounding the tumor, especially the brachial plexus anatomy, is critical to avoiding severe complications. Incomplete resection or leakage of the lymph could result in higher rate of recurrence.
