Computed tomographic evaluation of abdominal and pelvic abscesses

Area of Science:

• Radiology
• Medical Imaging
• Abdominal Imaging

Background:

• Abdominal and pelvic abscesses present diagnostic challenges.
• Differentiating abscesses from other soft-tissue masses is crucial for appropriate management.

Purpose of the Study:

• To analyze the computed tomography (CT) characteristics of abdominal and pelvic abscesses.
• To correlate the pathological development of abscesses with their CT appearance.

Main Methods:

• Retrospective analysis of CT scans from 29 patients with abdominal and pelvic abscesses.
• Evaluation of imaging findings in relation to pathological processes.

Main Results:

• Low-density areas within soft-tissue masses and definable walls/rims are common but not specific findings for abscesses.
• These findings can also be present in hematomas, inflammatory masses, and cystic/necrotic tumors.
• Extraluminal gas was the most specific CT sign, identified in 38% of patients.

Conclusions:

• While certain CT findings suggest abscesses, they lack specificity.
• The presence of extraluminal gas on CT is a highly specific indicator of abdominal and pelvic abscesses.
