Overview

Abdominal ultrasound scan may be helpful in the diagnosis of pseudomyxoma peritonei. Finding on ultrasound of patients with pseudomyxoma peritonei are hyper or/and hypoechogenic peritoneal masses or plaques in thickened areas.

Ultrasound

On abdominal ultrasound, pseudomyxoma peritonei is characterized by:

• Echogenic peritoneal masses or ascites with echogenic, immobile particles (unlike other mobile forms of particulate ascites such as haemoperitoneum or pus in the peritoneum)
• Medial displacement of the small intestinal loops
• U/S may also illustrate scalloping of the liver or spleen
