Small bowel obstruction due to inguinal hernia

Loops of small bowel dilated up to 4.2 cm in the central-left abdomen, with air-fluid levels.
Contents and gas in the ascending colon, gas in the rectum. The latter finding probably denotes an incomplete small bowel obstruction or a complete obstruction where the colonic contents have not yet been completely evacuated.
Prior cholecystectomy (known).
15 x 17 mm peripheral calcified nodule in the right upper abdomen, medial to the inferior rib - calcified lymph node? dropped gallstone?

• many mildly dilated small bowel loops, some with air-fluid levels, some with a string of pearls sign
• the transition point is a loop of ileum incarcerated in a large right inguinoscrotal hernia, showing a thickened, edematous wall and edema of its mesentery
• the efferent bowel loop is collapsed right to the ileocecal valve
• loop of sigmoid colon inside the same hernia, without signs of strangulation
• copious amount of fluid inside the hernia
• slightly hypoenhancing 9-mm lesion in hepatic segment 6, too small and hazy to characterize (due to movement artifact) 
• the gallbladder has been removed
• thick medial arm of left adrenal, no distinct lesion identified
• peripherally calcified right renal artery aneurysm 14 mm in diameter
• circumaortic left renal vein.
• small mural thrombi on the posterior aortic wall at the level of the celiac trunk
• bilateral moderate hydrocele

In summary:

1. Small bowel obstruction, perhaps incomplete, due to ileal loop incarceration in large right inguinoscrotal hernia. The incarcerated loop shows signs of strangulation. Incarcerated loop of the sigmoid colon without such signs in the same hernia.
2. Small calcified right renal artery aneurysm.
