Abdominal hernias: Radiological features

Area of Science:

• Radiology
• Gastroenterology
• General Surgery

Background:

• Abdominal wall hernias are common, with a 4-5% global incidence.
• Groin hernias are most prevalent (75%), followed by femoral (15%) and umbilical (8%).
• Males exhibit a higher prevalence (M:F ratio of 8:1).

Purpose of the Study:

• To outline the primary radiological findings in abdominal herniations.
• To highlight the utility of imaging in diagnosing complex hernia cases.
• To differentiate abdominal wall masses and identify hernia contents.

Main Methods:

• Review of conventional radiography, barium studies, ultrasonography, and Computed Tomography (CT).
• Focus on radiological features aiding in the diagnosis of abdominal wall hernias.
• Analysis of imaging's role in cases with diagnostic challenges like obesity or scarring.

Main Results:

• Imaging modalities can confirm suspected hernias when physical examination is inconclusive.
• Radiology helps differentiate palpable abdominal masses.
• Imaging visualizes hernia contents, including fat, bowel, and other organs.

Conclusions:

• Abdominal imaging is crucial for diagnosing abdominal wall hernias, especially in challenging clinical scenarios.
• Various imaging techniques provide essential information on hernia location and contents.
• Radiological findings are key to accurate diagnosis and management planning.
