When the probe was put in the retroperitoneal space, the crus of diaphragm could be identified and GSN and LSN could be found between the middle and medial crus of the diaphragm
Supine abdominal X-ray showed no dilated bowel loops, but there was an abnormal lucency at the right abdomen outlining the right crus of the diaphragm and extending along the right psoas muscle (Figure 1).

During regular dissection classes for medical students, we identified duplicated right crus of the diaphragm in an approximately 55-years-old male cadaver of South Indian origin.
Though the duplication of the right crus of the diaphragm has been reported, information about the frequency of its occurrence is scanty in the scientific literature.
In some cases, a total obstruction of the celiac trunk with only one concave impression in SMA was observed angiographically (Loffeld et al.), a slight narrowing of the SMA, the celiac trunk compressed by left crus of the diaphragm and an adenopathy and fibrous reaction around the celiac trunk and SMA (Cornell), and a moderate SMA stenosis without any significant hemodynamic implication (Edwards; Lord et al.).
Tahery verified the celiac trunk compression release after a division of the right crus of the diaphragm associated to ganglionectomy.
