Computed tomography (CT) accurately diagnoses acute mediastinitis (AM), a rare but dangerous condition. Early CT diagnosis is crucial for effective treatment and improved patient outcomes in suspected AM cases.

Area of Science:

  • Thoracic Surgery
  • Diagnostic Imaging
  • Infectious Diseases

Background:

  • Acute mediastinitis (AM) is a rare condition with high mortality if not diagnosed and treated promptly.
  • Clinical signs of AM are often non-specific, and plain chest X-rays lack diagnostic accuracy.
  • Antibiotic introduction has reduced AM incidence but not its associated mortality rate.

Purpose of the Study:

  • To evaluate the diagnostic value of computed tomography (CT) findings in patients with suspected acute mediastinitis.
  • To compare CT results with surgical findings, percutaneous drainage, and clinical outcomes.
  • To assess the accuracy of CT in identifying inflammatory changes in the mediastinum.

Main Methods:

  • Retrospective study of 23 patients clinically suspected of having AM.

  • Evaluation of CT scan results.
  • Comparison of CT findings with operative procedures, percutaneous drainage, and clinical course.

    • Main Results:

    • CT correctly diagnosed AM in 15 out of 23 patients; 8 patients had normal CT results.
    • CT identified diffuse infiltration of mediastinal fatty tissue in 3 patients.
    • Mediastinal fluid collections were detected in 12 patients, including infected hematomas (4) and abscesses (8).
    • CT accurately assessed the extent of inflammatory changes in all patients.

    Conclusions:

    • CT is a valuable tool for diagnosing acute mediastinitis.
    • CT enables precise assessment of the extent of mediastinal inflammation and fluid collections.
    • Early and accurate diagnosis via CT facilitates timely and adequate therapeutic interventions for AM.
