Overview

Spontaneous bacterial peritonitis must be differentiated from other diseases that cause fever and abdominal pain, such as peritonitis, pyelonephritis, and appendicitis.

Differentiating Spontaneous bacterial peritonitis from other Diseases

Spontaneous bacterial peritonitis presents as fever and pain in the abdomen. These symptoms may also be seen in other abdominal conditions such as:
