Abstract Objective: To evaluate the clinical value of the distribution types of the hilar and mediastinal high metabolic lymph nodes in the aged by PET/CT image. Materials and Methods: Sixty-one patients ≥60 years old underwent FDG PET/CT images. According to the distribution of the hilar and mediastinal high metabolic lymph nodes(HML), all patients were divided into 4 groups: patients without HML as group A, with bilateral HML as group B, with HML at the same side of the lung nodule or mass as group C, other patients as group D. Results: Of the 61 patients, 35(57.4%) patients had HML, 7 patients and 54 patients with and without hilar and mediastinal metastatic lymph nodes respectively. In group A, B, C and D, there were 0, 3, 4 and 0 patients with hilar and mediastinal metastatic lymph nodes respectively, and there were 26, 13, 2 and 13 patients without hilar and mediastinal metastatic lymph nodes respectively, P<0.001. Conclusion: The inccident rate of hilar and mediastinal high metabolic lymph nodes is high. The distribution types of HML is useful to find the malignant HML from the benign ones.
