This review details six unusual cases of pulmonary sequestration, highlighting varied radiographic presentations that mimicked other serious conditions like heart failure and tumors.

Area of Science:

Pulmonary Medicine
Radiology
Pediatric Cardiology

Background:

Pulmonary sequestration is a rare congenital lung malformation.
Accurate diagnosis is crucial for appropriate management.
Unusual presentations can complicate differential diagnosis.

Observation:

Six cases of pulmonary sequestration with atypical radiographic features were identified.
Three pediatric patients presented with congestive heart failure, raising suspicion for congenital heart disease.
One case involved a cystic sequestration mimicking a pneumatocele or infected cyst.

Findings:

Two sequestrations presented as solid mass lesions on imaging.
These solid mass lesions were misdiagnosed as mesothelioma, bronchogenic cyst, or carcinoma.

Related Experiment Videos

Congenital heart disease was suspected in children with congestive heart failure due to sequestration.

Implications:

Radiographic variations in pulmonary sequestration necessitate a broad differential diagnosis.
Early recognition of unusual features can prevent misdiagnosis and delayed treatment.
Understanding these atypical presentations improves diagnostic accuracy in pediatric and adult cases.
