Pneumatosis Intestinalis

In this article, we’ll discuss the basics of pneumatosis intestinalis, including its symptoms, causes, and how it’s diagnosed. We’ll also explore the importance of imaging in diagnosing and understanding this condition.

What is Pneumatosis Intestinalis?

Pneumatosis intestinalis is a condition where abnormal air pockets or gas-filled cysts develop within the walls of the intestines. These gas-filled cysts can be found anywhere in the gastrointestinal tract, from the stomach to the colon.

Common Symptoms

This condition can cause a range of symptoms, which may include:

  1. Abdominal Pain: Patients often experience abdominal discomfort or pain. The intensity can vary from mild to severe.
  2. Bloating: Abdominal bloating is a common symptom, which can make patients feel full or distended.
  3. Nausea and Vomiting: Some individuals may experience nausea and even vomiting.
  4. Diarrhea or Constipation: Changes in bowel habits can occur due to pneumatosis intestinalis.
  5. Blood in Stool: In severe cases, there might be blood in the stool.

Causes of Pneumatosis Intestinalis

The exact causes of pneumatosis intestinalis are not always clear, but there are several potential factors that can contribute to this condition:

  1. Gastrointestinal Conditions: Pneumatosis intestinalis can be associated with various gastrointestinal conditions, such as inflammatory bowel disease or celiac disease.
  2. Ischemia and infection of bowel: bowel that lacks blood flow can develop pneumatosis
  3. Infections: Certain infections, like Clostridium difficile, have been linked to pneumatosis intestinalis.
  4. Medical Procedures: In some cases, this condition may result from medical procedures or interventions, like mechanical ventilation.
  5. Certain Medications: Some medications, especially immunosuppressive drugs, can increase the risk.

Diagnosing Pneumatosis Intestinalis

Diagnosing pneumatosis intestinalis often involves a combination of medical history, physical examination, and imaging studies. Imaging, in particular, plays a crucial role in confirming the diagnosis and understanding the extent of the condition. Common imaging techniques used include:

  1. Abdominal X-Rays: X-rays can reveal characteristic air-filled cysts in the intestinal walls.
  2. CT Scans: Computed tomography (CT) scans provide detailed images and can help assess the severity of pneumatosis intestinalis.
  3. Ultrasound: In some cases, ultrasound may be used to detect air within the intestinal walls.
  4. Endoscopy: This involves inserting a thin, flexible tube with a camera into the digestive tract to visually examine the intestines and take biopsies if needed.

Treatment and Management

The treatment of pneumatosis intestinalis depends on its underlying cause and severity. In mild cases, it may resolve on its own. However, in more severe cases or when associated with other medical conditions, treatment options may include:

  1. Managing Underlying Conditions: Treating any underlying gastrointestinal conditions or infections is essential.
  2. Supportive Care: Patients may receive supportive care to manage symptoms, such as pain relief and hydration.
  3. Surgery: In rare cases, when pneumatosis intestinalis causes complications like bowel obstruction or perforation, surgery may be necessary.


Pneumatosis intestinalis is a gastrointestinal condition that can be challenging to diagnose.  Imaging techniques, such as X-rays, CT scans, and endoscopy, are vital tools for confirming the diagnosis and assessing its severity. Remember that early detection and treatment play a crucial role in managing pneumatosis intestinalis and addressing any underlying causes.
