Overview
Ultrasound may be helpful in the diagnosis of toxic megacolon. Findings on an ultrasound suggestive of toxic megacolon include loss of haustra coli of the colon, hypo-echoic and thickened bowel walls with irregular internal margins in the sigmoid and descending colon and significant dilation of the transverse colon.
Ultrasound
- Ultrasound may be helpful in the diagnosis of toxic megacolon. Findings on an ultrasound suggestive of toxic megacolon include:[1][2][3][4][5]
- Loss of haustra coli of the colon,
- Hypo-echoic and thickened bowel walls with irregular internal margins in the sigmoid and descending colon,
- Prominent dilation of the transverse colon (>6 cm),
- Insignificant dilation of ileal bowel loops (diameter >18 mm) with increased intraluminal gas and fluid.
