Abstract:
Acute mediastinitis (AM) has become a rare disease since the introduction of antibiotics but still has an unchanged high mortality-rate if the diagnosis is not readily established, and adequate therapy is performed. Clinical signs of AM are often uncharacteristic, plain chest films do not allow a reliable diagnosis because of lack of sensitivity as well as specificity. In a retrospective study the CT-results of 23 patients clinically suspect for AM were evaluated in order to determine the diagnostic value of CT-findings were compared to operation, percutaneous drainage procedures and clinical course. In 15 patients the diagnosis of AM was established correctly by CT, 8 patients were reported normal. Diffuse infiltration of mediastinal fatty tissue was found in 3 patients, mediastinal fluid collections were demonstrated in 12 (infected hematomas = 4, abscess formation = 8). The extension of inflammatory changes could be exactly assessed by CT in all patients.
Insights
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.
