| 目的 评价99Tcm-DX淋巴显像对淋巴管肌瘤病（LAM）肺外病变的诊断价值。方法 回顾性分析经临床或病理证实的39例LAM患者的淋巴显像图像，总结该病的淋巴显像特点。结果 39例LAM患者中，33例（33/39，84.62%）伴乳糜胸，99Tcm-DX淋巴显像可显示84.85%（28/33）的乳糜胸，表现为患侧胸部分放射性增高；16例（16/39，41.03%）伴乳糜腹，99Tcm-DX淋巴显像均可显示（16/16，100%），表现为腹盆部不同程度的放射性摄取增高；34例（34/39，87.18%）伴腹/盆腔淋巴管肌瘤，99Tcm-DX淋巴显像均可显示淋巴管肌瘤（34/34，100%），表现为髂、腰及纵隔粗大、团、串状分布的放射性摄取异常增高灶；8例（8/39，20.51%）伴下肢淋巴水肿，3例LAM伴阴囊淋巴水肿，99Tcm-DX淋巴显像均可显示；24例（24/39，61.54%）伴左静脉角区放射性浓聚。结论 99Tcm-DX淋巴显像可判断LAM患者肺外病变分布，评估病情严重程度。 |

| Objective To explore the value of 99Tcm-DX lymphoscintigraphy in detecting extra-pulmonary lesions of 99Tcm-DX lymphangioleiomyomatosis (LAM). Methods The lymphoscintigraphic images of 39 patients with LAM diagnosed clinically or confirmed by pathology were retrospectively analyzed. The lymphoscintigraphic imaging features of LAM were observed. Results Among 39 LAM patients, 33 (33/39, 84.62%) had chylothorax. 99Tcm-DX lymphoscintigraphy showed chylothorax in 28 cases (28/33, 84.85%), presenting as increased radioactivity in the affected side of the chest. Sixteen patients (16/39, 41.03%) had chyloperitoneum and all were detected with 99Tcm-DX lymphoscintigraphy (16/16, 100%), showing different degrees of increased uptake of radioactivity in the abdomen and pelvis. 99Tcm-DX lymphoscintigraphy showed all 34 cases (34/34, 100%) of abdominal/pelvic lymphangiomyoma (34/39, 87.18%), the lesions of ilium, waist and mediastinum manifested as abnormal uptake of radioactivity with thick, clusters and clusters distribution. Lower limbs lymphedemas were found in 8 patients (8/39, 20.51%), among them 99Tcm-DX lymphoscintigraphy showed 3 cases with lymphedema of scrotum. Radiation concentration on the left subclavian-jugular venous angle was detected in 24 patients (24/39, 61.54%). Conclusion 99mTc-DX lymphoscintigraphy could describe the distribution of extra-pulmonary lesions in LAM patients and evaluate the severity of disease. |
