Appendicolith. Significance in acute appendicitis and demonstration by computed tomography

Area of Science:

• Radiology
• Gastroenterology
• Surgical Pathology

Background:

• Periappendical abscess is a complication of acute appendicitis.
• Appendicoliths, calcified fecaliths, are often associated with appendicitis and can indicate a higher risk of complications.

Observation:

• A case of periappendical abscess was diagnosed using computed tomography (CT).
• CT demonstrated an appendicolith within a large abscess cavity, correlating with clinical findings.
• Plain film radiography failed to detect the appendicolith.

Findings:

• Computed tomography (CT) showed higher sensitivity than plain film radiography in detecting appendicoliths.
• The presence of an appendicolith in this case was crucial for diagnosis.
• The study suggests the actual incidence of appendicoliths in acute appendicitis may be underestimated.

Implications:

• CT imaging is superior to plain radiography for identifying appendicoliths in cases of suspected periappendical abscess.
• Increased detection of appendicoliths via CT could lead to revised estimates of their prevalence in acute appendicitis.
• Enhanced diagnostic accuracy through CT may improve patient management and outcomes for appendicitis complications.
