Idiopathic pneumoperitoneum, a rare condition of air in the abdominal cavity without apparent cause, was diagnosed in an elderly male. Surgical exploration revealed no underlying pathology, and the patient recovered fully.

Area of Science:

  • Gastroenterology
  • Abdominal Surgery
  • Diagnostic Imaging

Background:

  • Idiopathic pneumoperitoneum is a rare clinical finding characterized by the presence of free air in the peritoneal cavity without a clear etiology.
  • Spontaneous perforation of the gastrointestinal tract is the most common cause of pneumoperitoneum, but in idiopathic cases, no such cause is identified.

Purpose of the Study:

  • To report a case of idiopathic pneumoperitoneum in a 75-year-old male presenting with abdominal pain.
  • To highlight the diagnostic and management challenges associated with this rare condition.

Main Methods:

  • Case presentation of a 75-year-old male with vague left-sided abdominal pain.
  • Diagnostic workup including physical examination and imaging (implied by repeat chest X-ray).

  • Surgical intervention via exploratory laparotomy.

    • Main Results:

    • Exploratory laparotomy was negative for any identifiable cause of pneumoperitoneum.
    • The patient experienced an uneventful postoperative recovery.
    • A repeat chest X-ray prior to discharge showed no evidence of pneumoperitoneum.

    Conclusions:

    • Idiopathic pneumoperitoneum can present without clear etiology and may resolve spontaneously or after diagnostic laparotomy.
    • While surgical exploration is often performed, it may not reveal an underlying cause in idiopathic cases.
    • This case underscores the importance of considering rare diagnoses in the differential for abdominal complaints.
