The gallbladder is not seen at anatomical location due to prior resection.
Case Discussion
Features on CT scan consistent with superior mesenteric artery syndrome.
Normally, the aortomesenteric angle and aortomesenteric distance are 28-65° and 10-34 mm, respectively. In SMA syndrome, both parameters are reduced, with values of 6° to 22° and 2 to 8 mm.
