title: [A giant retropharyngeal lipoma showing no change in clinical presentation and size within a two-year follow-up: a case report].
abstract: Retropharyngeal tumors are rare. They typically originate from the neighboring anatomical structures or from the retropharyngeal space itself. Retropharyngeal lipomas are even rarer. A 75-year-old male patient presented with complaints of dyspnea, dysphagia, snoring, and obstructive sleep apnea. Computed tomography showed a giant mass measuring 125 x 81 x 27 mm in the retropharyngeal space, compressing the larynx, trachea, and esophagus, and extending to the thoracic inlet. The mass had regular margins, exhibited low attenuation, and was homogeneously hypodense. After intravenous contrast administration, there were thin septa formations within the lesion that did not show contrast enhancement. There was no invasion to the neighboring muscular structures. The lesion was considered a lipoma. Surgery was not performed due to the cardiovascular problems of the patient. During a two-year follow-up, there were no changes in the size and tissue characteristics of the mass, nor any mass-related clinical problems.
