Fever, abdominal pain, and lymphocytic ascites in a young immigrant from western Africa.

Tuberculous peritonitis is an uncommon disease in countries with low tuberculosis (TB) incidence, most often affecting non-white race, foreign-born individuals. We describe a case of TB with peritoneal involvement in a 32-year-old man immigrated to Italy from Burkina Faso, who presented with a history of fever, malaise, abdominal pain and abdominal swelling. Due to its nonspecific clinical presentation and paucibacillary nature, diagnosis of tuberculous peritonitis can be challenging, and requires a high index of suspicion. This report highlights the diagnostic challenges posed by tuberculous peritonitis and emphasizes the importance of imaging (computed tomography, CT) in identifying typical findings, and the value of histological examination of tissue specimens from peritoneum or any site of suspected TB as a tool for diagnosis confirmation.
