WebJan 22, 2024 · FCT was defined as non-uniform cortical thickening showing single or multiple bulges protruding from the lymph node cortex. When LOH was suspected, the short-axis diameter was substituted for the cortical thickness. LOH was judged as positive only when the short-axis diameter was ≥ 4 mm on MRI . When LOH or FCT was observed, the … Weba more rounded shape, in which the long-to-short axis ratio decreases, or eccentric cortical hypertrophy (16,34). A com-monly used size threshold in the pelvis accounts for this change in morphology, using 10 mm in short-axis diameter for ovoid lymph nodes while using a smaller threshold (8 mm) as a cutoff for rounded lymph nodes (34).

WebSep 1, 2024 · A normal lymph node has an oval or reniform shape owing to a central fatty hilum and a thin outer cortex, with a long-axis/short-axis ratio greater than 2. Lymphatic flow enters the cortex through the afferent channel and then exits the hilum through the efferent channel ( Fig 1 ). WebUsually, the presence of lymph nodes with a short-axis diameter greater than 10 mm prompts a referral for an invasive diagnostic test such as EBUS-TBNA. Interestingly, previous studies showed that lymph nodes with a short-axis diameter less than 10 mm could contain malignant cells ( 12, 13) and those greater than 10 mm can be reactive in nature. WebThe mean number of lymph nodes on a representative section was 1.1 (range, 0-6); 72.4% of CT patients showed one to three lymph nodes per zone. There was a significant size difference (p less than 0.001) between lymph nodes residing in the superior mediastinum compared with those in the middle mediastinum contiguous to the carina. local.ch/fr
