Background: The most common site of paragonimiasis is in the lungs. The migratory route passes through the duodenal wall, peritoneum, and diaphragm to the lungs; thus, the thoracic cavity and central nervous system, as well as the liver, intestine, and abdominal cavity may be involved. Here, we present a case of intraperitoneal paragonimiasis without other organ involvement, mimicking tuberculous peritonitis.
Case Summary: A 57-year-old man presented with recurrent abdominal pain for 4 wk. Physical examination revealed tenderness in the right lower quadrant. Laboratory findings showed complete blood counts within the normal range without eosinophilia. Multiple reactive lymph nodes and diffuse peritoneal infiltration were noted on abdominal computed tomography (CT). There were no abnormalities on chest CT or colonoscopy. Intraoperative findings of diagnostic laparoscopy for the differential diagnosis of tuberculous peritonitis and peritoneal carcinomatosis included multiple small whitish nodules and an abscess in the peritoneum. Pathological reports confirmed the presence of numerous eggs of (). A postoperative serum enzyme-linked immunosorbent assay revealed positivity. Persistent and repetitive history-taking led him to retrospectively recall the consumption of freshwater crab. After 3 d of treatment with praziquantel (1800 mg; 25 mg/kg), he recovered from all symptoms.
Conclusion: In patients who require diagnostic laparoscopy for the differential diagnosis of tuberculous peritonitis and peritoneal carcinomatosis, repetitive history-taking and preoperative serologic antibody tests against may be helpful in diagnosing intraperitoneal paragonimiasis without other organ involvement.

Peritoneal tuberculosis: the diagnostic challenge must not preclude treatment.
BMJ Case Rep
November 2024
Internal Medicine Department, Coimbra University Hospital Centre, Coimbra, Portugal.
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.

Article Synopsis
- Tuberculosis (TB) is a complex infection that can affect any part of the body, with many people unknowingly carrying it in a latent form, and there's an increasing number of abdominal TB cases.
- Diagnosis is challenging due to overlapping symptoms with other conditions, especially in immunocompromised individuals, making early detection difficult.
- A case study of a 71-year-old woman illustrates the difficulties in diagnosing peritoneal tuberculosis, which was mistaken for peritoneal carcinomatosis, highlighting the need for increased awareness and scrutiny in similar cases.
Tuberculosis Peritonitis Resulting in Small Bowel Obstruction.

General Surgery, Methodist Le Bonheur Germantown Hospital, Memphis, USA.
Article Synopsis
- Tuberculosis (TB) peritonitis can cause small bowel obstruction, but it's hard to diagnose due to vague symptoms; a case study showed a 30-year-old woman after a trip to Vietnam with gastrointestinal issues.
- CT scans detected a mass in her intestine, leading to positive TB tests and biopsy results indicating a mycobacterial infection.
- Despite starting treatment, she faced complications, requiring surgery for a bowel obstruction, highlighting the need for TB tests in patients with worsening gut symptoms.
Article Synopsis
- A nine-year-old boy with trisomy 21 and end-stage renal disease showed signs of peritonitis linked to his peritoneal dialysis catheter.
- After initial antibiotic treatment failed, the catheter was surgically removed, revealing a non-tuberculous mycobacterial infection that improved his symptoms.
- He later transitioned to hemodialysis and received a successful kidney transplant eight months later, highlighting the importance of considering atypical infections in similar cases.
Atypical tuberculous peritonitis presenting as a peritoneal pseudocyst in an immunocompetent adult: insights from a case and literature review.

Department of Internal Medicine, Hôpital Provincial Général de Référence de Bukavu (HPGRB), Bukavu, South Kivu, Democratic Republic of the Congo.
Background: Tuberculous peritonitis often presents with nonspecific symptoms that can lead to diagnostic challenges, particularly when manifesting as peritoneal pseudocysts. This study highlights the clinical complexity and diagnostic approach of tuberculous peritonitis presented as a pseudocyst in an immunocompetent adult, an atypical scenario that is rarely documented.
Case Presentation: We report a detailed case of a 41-year-old man presenting with abdominal distension, pain, and significant weight loss over four months.
