Rationale:

Acute otitis media is a common disease in early childhood, and is usually caused by Streptococcus pneumoniae (S. pneumoniae). Acute mastoiditis is a complication of acute otitis media and can involve not only the mucoperiosteum of the middle ear but can also spread to the periosteum by destroying the mastoid bone (acute coalescent mastoiditis). In addition, the infection can extend through the surrounding bones or the emissary veins beyond the mastoid's air cells, leading to subperiosteal abscesses.

Patient's Concern:

A 16-month-old female patient was hospitalized due to the purulent discharge of the left ear and the symptoms of right mastoiditis (swelling and redness of the skin).

Diagnosis:

Bilateral acute coalescent mastoiditis caused by S. pneumoniae infection. The computer tomography revealed bilateral bone destruction of the mastoid and abscesses found behind the auricle on both sides.

Interventions:

The patient underwent intravenous antibiotic therapy and surgical treatment.

Outcomes:

The patient was discharged 14 days after hospitalization with an improved condition.

Lessons:

Improperly treated acute coalescent mastoiditis can lead to extracranial and intracranial complications, sometimes serious and even life-threatening. Complications are prevalent in children under 2 years, in whom the disease progresses more rapidly and severely. The vaccination with a 13-valent vaccine may not result in sufficient immunity against S. pneumoniae, a predominant pathogen in children affected by acute coalescent mastoiditis.
