Introduction and importance: Peritoneal tuberculosis (PTB) is an infrequent clinical condition that frequently eludes diagnosis. The scarcity of PTB cases underscores the necessity for heightened vigilance within clinical settings to detect its presence. Notably, there has been a noticeable increase in PTB incidence in recent years. Mycobacterium tuberculosis is the causative agent responsible for PTB, affecting multiple gastrointestinal components such as the peritoneum and hepatobiliary system. Peritoneum is a rare site for TB with broad unspecific symptoms. It can be asymptomatic to periodic signs or mimic the positive peritonitis examinations like our case.
Case presentation: We have reported a case of 19-year-old male experiencing progressive abdominal pain. The presence of generalized tenderness and guarding on physical examination prompted us to perform an urgent laparotomy due to suspicion of peritonitis. During the surgery, we observed the peritoneum exhibiting widespread nodularity, resembling a disseminated seeding pattern, along with mild ascites, which raised our suspicion of peritoneal tuberculosis. Subsequently, cytological analysis of the ascitic fluid and histopathological examination of the lesions confirmed our diagnosis of peritoneal TB.
Clinical discussion: We have shared our experience in facing PTB and reviewed recent papers to find further relevant information. The common presentations, probable causes, the role of imaging in diagnosis and the management are discussed for better management strategy and the best surgical decision.
Conclusion: Peritoneal tuberculosis is a rare condition with challenging diagnosis. Key symptoms include vomiting, abdominal pain, ascites, weight loss, and fever. Prompt recognition and treatment are vital for better outcomes.
