OBJECTIVE: The purpose of this study was to investigate the age-related morphologic changes of the lateral retropharyngeal lymph nodes using MR imaging. STUDY DESIGN: The maximal axial diameter of the nodes was measured on the MR image in 120 healthy subjects (younger group 6-19 years (n = 40), middle group 20-38 years (n = 48), older group 42-74 years (n = 32)). Between-group differences in the diameter of the nodes were analyzed. RESULTS: Mean values of the maximal axial diameter of the nodes were 9.0 +/- 1.6 mm, 6.6 +/- 1.7 mm, and 5.3 +/- 1.6 mm, corresponding to younger group, middle group, and older group, respectively ( P <.01). CONCLUSION: The information obtained in the current study is useful for the differential diagnosis of normal and abnormal lateral retropharyngeal lymph nodes according to age.
