The shadow (turquoise line) is just cranial to the cranial border of the cricoid cartilage.
In the case of pathological retroperitoneal LNMs, the cranial border was extended to a maximum of renal vessels.
A low signal intensity band (arrow) is seen on the cranial border of the cyst with a high intensity band on the opposite side.
Last, other findings reported in the literature include the leakage of contrast agent anterior to the medial margin of the scapula (Fig. 10), pseudo-synovitis over the cranial border of the subscapularis tendon and the biceps anchor, and widening of the subscapular recess [2].
When lymph node metastases (LNMs) were evident on CT and/or pathological tracer uptake was seen on PET, an additional CTVLN was defined with a 5-mm margin around the vessels, including the external iliac, internal iliac, and obturator nodes, to a cranial border at the level of the promontory.
It was graded as caudal if the cranial border of the ilium was cranial to the cranial endplate of L7, intermediate if the cranial border of the ilium was superimposed on the cranial half of L7, and cranial if the cranial border of the ilium was superimposed on the caudal half of L7.
