Abstract:
We present the cases of 3 previously healthy patients who became ill with a very sudden and painful external otitis due to Pseudomonas aeruginosa. At the acute stage, diagnosis was difficult in all these patients because of marked periauricular swelling and radiological mastoiditis. The latter sign has not been reported earlier in association with external otitis in nonimmunocompromised patients. All patients made a full recovery with appropriate treatment.
Insights
Pseudomonas aeruginosa caused sudden, painful external otitis in three healthy patients. Diagnosis was challenging due to swelling and mastoiditis, a rare sign in non-immunocompromised individuals.
Area of Science:
- Otolaryngology
- Infectious Diseases
Background:
- External otitis, commonly known as swimmer's ear, is an infection of the outer ear canal.
- Pseudomonas aeruginosa is a common bacterium that can cause various infections.
Observation:
- Three previously healthy patients presented with acute, severe external otitis.
- Symptoms included sudden onset, significant pain, and marked periauricular swelling.
- Radiological mastoiditis was observed in all cases, which is unusual for external otitis in non-immunocompromised patients.
Findings:
- The causative agent was identified as Pseudomonas aeruginosa.
- Diagnostic challenges arose from extensive swelling and mastoiditis, complicating early identification of external otitis.
- All patients achieved full recovery following appropriate antibiotic treatment.
Implications:
- This case series highlights a rare presentation of Pseudomonas aeruginosa external otitis with mastoiditis in healthy individuals.
- It underscores the importance of considering unusual presentations and diagnostic signs in external otitis.
- Prompt and appropriate treatment leads to favorable outcomes even in severe cases.
