An infant with a hyperlucent chest mass: An unexpected diagnosis

Area of Science:

• Pediatric Pulmonology
• Thoracic Surgery
• Neonatal Medicine

Background:

• Pneumatocele is a rare cause of cystic lung disease in infants.
• Infantile cystic lung disease can present with significant respiratory compromise.

Observation:

• A four-month-old infant presented with chronic respiratory distress without preceding infection.
• Imaging revealed a tension pneumothorax secondary to a large lung cyst.
• Surgical intervention with left lower lobectomy was performed for the suspected pneumatocele.

Findings:

• Histopathology confirmed the diagnosis of pneumatocele.
• The infant remained clinically stable 16 months post-surgery.
• This case highlights a unique presentation of pneumatocele in infancy.

Implications:

• Pneumatocele should be considered in the differential diagnosis of infantile cystic lung disease.
• Early diagnosis and intervention are crucial for managing tension physiology in infants with pneumatocele.
• Further research into the etiology and optimal management of infantile pneumatoceles is warranted.
