[A case of lipoma in retropharyngeal space]

One case of lipoma was reported in retropharyngeal space. Oropharyngeal CT showed: tumor's size was 59.2 mm x 28.4 mm, the boundary was clear, and the surrounding tissue was pressed obviously. Retropharyngeal space lies between posterior wall of the pharynx and prevertebral space, and contains fat and lymphoid tissue. Retropharyngeal space tumor often showed no clinical symptoms early. Tumor could show airway obstruction when growing up. Surgical operation is the only treatment method.
