case_images: Coronal view of magnetic resonance imaging abdomen demonstrating an upside-down U-shape
  dilated sigmoid loop in the left upper quadrant giving a "coffee-bean" appearance. Fetus
  can also be seen in the image.

case_images: Magnetic resonance imaging of the abdomen revealed large bowel distention with abrupt transition point in the region of the distal descending and proximal sigmoid colon with swirling of mesentery and collapse of distal sigmoid and rectum highly suggestive of SV without free intraperitoneal air (Figure 1).
case_images: Endoscopic view of the classic "whirl sign" with a spirally twisted viable appearing
  colonic mucosa.

case_images: SV with the distal point of torsional obstruction in the distal sigmoid colon showing the classic "whirl sign" with a spirally twisted viable appearing colonic mucosa (Figure 2). Successful complete decompression was achieved by advancing the endoscope proximal to the volvulus followed by endoscopic suctioning of gas and liquid stool, and finally a 14-French soft rectal tube placement left to gravity.
