The distinction between tuberculous peritonitis and peritoneal carcinomatosis is extremely difficult in patients with omental cake appearance on computed tomography and elevated CA-125 level. A 21-year-old female presented with abdominal distention, diarrhea, nausea, fever, weight loss, and night sweats. Serum CA-125 level was 563 U/L (normal range: <35 U/L) and other tumor markers were within normal range. Radiologic studies showed massive ascites, smooth minimal thickening and increased contrast enhancement of peritoneum, omental nodularities, hepatomegaly, and right pleural effusion. No underlying malignancy that could cause this condition was detected clinically and radiologically. Ultrasound-guided omental tru-cut biopsy was performed to exclude carcinomatosis peritonei. Histopathologic examination showed small-medium-sized granulomas with caseous necrosis. Molecular microbiology tests of biopsy specimens confirmed diagnosis of tuberculosis. In conclusion, tuberculous peritonitis should be in differential diagnosis of a patient with ascites, omental nodularities and elevated serum CA-125 levels.

Infectious complications in peritoneal dialysis (PD) remain a constant challenge, with atypical pathogens posing significant risks. This case from Thailand highlights the rare occurrence of , an often-overlooked non-tuberculous mycobacterium (NTM), as the causative agent in a catheter-related exit-site infection that progressed to peritonitis. Initially misattributed to from preceding exit-site infections, was ultimately identified as the primary pathogen through multiple effluent cultures and advance polymerase chain reaction sequencing.

Peritoneal tuberculosis (TB) is a rare extrapulmonary form of TB that often mimics ovarian malignancy, posing diagnostic challenges. This report presents a 16-year-old Jordanian female with abdominal distension, weakness, anorexia, and night sweats. Initial imaging, including contrast-enhanced computed tomography (CT), revealed compartmentalized ascites, peritoneal thickening, and enlarged ovaries with masses, suggesting possible ovarian malignancy.

Autoimmune hepatitis (AIH) is a distinct clinical entity with variable presentations and diverse clinical outcomes, characterized by autoimmune-mediated injury to the liver. The detection of autoantibodies and histological features consistent with autoimmune injury is crucial for diagnosing AIH. Early identification and treatment are essential to prevent progression to cirrhosis.

Article Synopsis
- Peritoneal tuberculosis is a rare form of TB that occurs outside the lungs, primarily affecting individuals in countries with high TB prevalence, making travel from these areas a risk factor.
- Diagnosing this condition is challenging due to overlapping symptoms with other illnesses, which can delay treatment and worsen outcomes.
- A case study highlights a woman in her mid-50s who experienced severe symptoms, leading to various diagnostic procedures, with TB ultimately isolated from her fluid, allowing her to successfully complete a 6-month anti-TB treatment.
