Computed tomography (CT) aids in diagnosing acute cholecystitis, identifying gallstones and inflammation. This review details CT findings, pitfalls, and its advantages over other imaging methods for abdominal inflammation.

Area of Science:

  • Radiology
  • Gastroenterology
  • Abdominal Imaging

Background:

  • Acute cholecystitis often presents with symptoms mimicking intra-abdominal abscesses.
  • Patients may undergo abdominal CT scans due to these concerning symptoms.

Purpose of the Study:

  • To review the pathophysiology, clinical presentation, and CT findings of acute cholecystitis.
  • To discuss diagnostic pitfalls and complications.
  • To highlight scenarios where CT excels over ultrasound or hepatobiliary scintigraphy.

Main Methods:

  • Review of literature on acute cholecystitis and CT imaging.
  • Analysis of characteristic CT findings: gallstones, gallbladder wall thickening, distention, pericholecystic fluid, and stranding.
  • Discussion of diagnostic challenges and comparative imaging modalities.

Main Results:

  • CT demonstrates key features of acute cholecystitis including gallstones, gallbladder wall thickening, distention, pericholecystic fluid, and pericholecystic stranding.
  • Potential pitfalls and complications in CT diagnosis are identified.
  • Specific clinical scenarios favoring CT over ultrasound or hepatobiliary scintigraphy are outlined.

Conclusions:

  • CT is a valuable tool for diagnosing acute cholecystitis, especially when intra-abdominal inflammation is suspected.
  • Understanding CT findings and limitations is crucial for accurate diagnosis.
  • CT offers advantages in specific situations compared to ultrasound and hepatobiliary scintigraphy.
