[Giant cervical lipoma adjacent to carotid artery: a case report and literature review]. / Gigantskaya lipoma shei, prilezhashchaya k sonnoi arterii: klinicheskii sluchai i obzor literatury.

ABSTRACT

BACKGROUND: Cervical lipomas accompanied by neurovascular compression are extremely rare and require surgical treatment in case of appropriate symptoms. The preferable method is gross total resection, as otherwise they tend to recur. Invasive growth is not typical for lipomas. However, large tumors can involve adjacent nerves and vessels and significantly complicate resection. MATERIAL AND METHODS: We present a 57-year-old patient who underwent resection of giant soft tissue cervical lipoma invading neurovascular bundle and compressing the oropharynx and esophagus with dysphagia and positional asphyxia. The patient was followed-up for previous 5 years. Resection was necessary due to tumor enlargement with appropriate symptoms. Searching for literature data was performed in the Pubmed, Medline, EMBASE, Cochrane Library and eLibrary databases. RESULTS AND DISCUSSION: Gross total resection of 7-cm tumor was accompanied by mobilization of hypoglossal and vagus nerves, common, external and internal carotid arteries and jugular vein with repositioning of the oropharynx and esophagus. There was mild Horner's syndrome in early postoperative period. The patient was discharged in 4 days after surgery with regression of complaints. We found only 5 reports describing giant cervical lipomas invading neurovascular bundle. CONCLUSION: Giant cervical lipomas are extremely rare, and total resection with preservation of critical structures is possible in a specialized hospital.
