1–1: MR lymphography (sagittal view) Case 1: A 54-year-old cervical cancer patient. The MRI scan of the pelvic lymphatic system before lymphography showed no obvious lymph node metastases. The lymphography lateral map shows an irregular shape of the obturator lymph nodes (Ob. L.N.), and the iliac blood vessel lymph nodes (I.B. L.N.) show filling defects. The lymphatic shape was not continuous. MR lymphography in this patient was acquired using a slow subcutaneous injection of 15 ml Gadodiamide and 4 ml 2% lidocaine in the labia majora pudendi followed by a 30 second massage of the injection site. MRI shows the lymph nodes (L.N.) and lymphatic vessels (L.Tube). 1–2: Lymphography (coronal view) Case 1. The contrast with lymphatic (coronal view) irregular shape of the bilateral iliac blood lymph nodes (I.B.L.N.) and the right obturator lymph nodes (Ob.L.N.). A filling defect and the absence of the left inguinal lymph nodes is shown.
