However, there are many uncommon peritoneal diseases including malignant peritoneal mesothelioma, primary sclerosing encapsulating peritonitis, intraperitoneal loose body,peritoneal ecchinococcosis, primary serous papillary carcionoma of peritoneum, extrapelvic endometriosis, ruptured ovarian teratoma with peritoneal dissemination and peritoneal inclusion cyst. Knowledge of those imaging findings is helpful in making diagnosis or narrowing differential diagnosis.
