[Peripharyngeal abscess. Apropos of 2 cases]

Area of Science:

• Infectious Diseases
• Surgical Pathology
• Anatomy

Background:

• Despite antibiotic availability, peripharyngeal abscesses persist as a clinical challenge.
• Mediastinitis, an infection of the mediastinum, is a rare but serious complication of deep neck infections.
• Understanding the anatomical pathways of infection spread is crucial for timely diagnosis and treatment.

Observation:

• A case of retropharyngeal abscess progressing to mediastinal abscess is presented.
• Another patient with a lateropharyngeal abscess experiencing significant respiratory distress is detailed.
• These cases illustrate the potential for rapid and severe downward spread of infection from the neck.

Findings:

• Pathological processes in the neck can directly extend or spread via fascial planes into the thoracic cavity.
• The contiguous spread and fascial plane dissection are key mechanisms for deep neck infections to involve the mediastinum.
• Early recognition of deep neck infections is vital to prevent catastrophic thoracic complications.

Implications:

• This highlights the need for vigilance in diagnosing and managing deep neck infections, even with antibiotic use.
• Prompt surgical and medical intervention is critical for patients with suspected mediastinal involvement secondary to neck abscesses.
• Enhanced anatomical understanding aids in predicting and managing the spread of these infections, improving patient outcomes.
