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, hypoechoic 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]
- Loss of haustra coli of the colon
- Hypoechoic 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
