Peritoneal tuberculosis, also known medically as tuberculous peritonitis, is mainly due to peritoneal exudation after infection of the intestine by Mycobacterium tuberculosis. The main symptoms of tuberculous peritonitis are fever, abdominal pain, bloating, ascites, abdominal wall tenderness, abdominal masses, and systemic symptoms. Fever is the most common symptom of tuberculous peritonitis, mostly low and moderate fever, some patients have tachypnoea fever, and exudative and caseous patients may have retention fever. Patients may have varying degrees of abdominal pain, mostly persistent vague or dull pain, mostly in the lower abdomen around the umbilicus, sometimes in the whole abdomen, with a kneading sensation during physical examination. Patients may present with abdominal distention, but sometimes without significant ascites, which may be caused by symptoms of tuberculosis toxicity or peritonitis with intestinal dysfunction. Small and moderate amounts of ascites are common in most patients, and mobile turbid sounds may appear with a tenderness of the abdominal wall when the amount of ascites is high. Some patients may develop abdominal masses, mostly located in the middle and lower abdomen, and the size of the masses varies, sometimes in the form of transverse masses or nodular sensation, and some have intestinal-shaped changes with light tenderness. Some patients may develop systemic symptoms, such as diarrhea, constipation, alternating constipation, and also liver enlargement and fatty liver due to malnutrition. Some patients with tuberculosis will have pulmonary symptoms, such as cough, sputum, night sweats, etc., along with anemia, emaciation, nutritional deficiency, orchitis, etc. Some patients may see symptoms such as chills and high fever, and women of childbearing age may experience menopause.
