The retropharyngeal space is a potential space located posterior to the pharynx that contains areolar fat and lymph nodes. It allows for movement of the pharynx during swallowing and respiration. Lesions and fluid collections like abscesses or hematomas can develop in this space. Imaging like CT scans are useful for evaluating these conditions. Retropharyngeal abscesses require prompt treatment with antibiotics and drainage to prevent airway complications. Lymph nodes in this region can metastasize early from cancers like nasopharyngeal carcinoma.
