Sonographic findings include irregularly dispersed echodense masses which show no acoustic shadowing; they may also have an echogenic wall with an anechoic interior. These masses adhere to the bowels and abdominal wall and float with change in patient position. Calcification has also been described in pseudomyxoma peritonei, secondary to ovarian papillary mucinous cystadenocarcinoma. The ultrasound appearance may differ in benign and malignant disease. Septation probably represents margins of the mucinous implants.
CT is distinctive in that the gelatinous nature of the deposit produces a mantle of low-density material over the surface of the liver causing scalloping of its margins, in association with the cystic peritoneal collection. Walls may show some calcification. The pressure of the material prevents bowel loops floating up, which may help to differentiate from ascites.
On MRI the gelatinous material coats the peritoneal surface and causes scalloping similar to that seen on CT scan. Septae are more easily seen. There is enhancement, which helps differentiate from ascites. The multiplanar capability of MRI will demonstrate the extent of the disease.
