Submasseteric abscesses, often linked to dental issues, pose diagnostic challenges. While CT imaging is common, Magnetic Resonance (MR) imaging sometimes offers superior visualization of these masticator space lesions.

Area of Science:

  • Radiology
  • Oral and Maxillofacial Surgery
  • Infectious Diseases

Background:

  • Submasseteric abscesses are infections located within the masticator space, frequently associated with dental pathology.
  • Accurate diagnosis is crucial for effective management and preventing complications.

Observation:

  • This study reviewed five cases of submasseteric abscess.
  • Computed Tomography (CT) was the primary imaging modality used.
  • Limitations of CT in defining lesion extent were noted in several cases.

Findings:

  • Magnetic Resonance (MR) imaging provided better lesion definition compared to CT in some instances.
  • Radiologic findings were correlated with pathological findings.
  • Dental disease was a common preceding condition in affected patients.

Implications:

  • The findings suggest that MR imaging should be considered in the diagnostic workup of suspected submasseteric abscesses, especially when CT is inconclusive.
  • Improved imaging interpretation can lead to timely and appropriate treatment.
  • Understanding radiologic-pathologic correlations aids in surgical planning and patient care.
