Diagnosis With Brief Discussion
- Diagnosis
- Intralobar sequestration with fungus ball
- Radiologic Findings
- There is a 5.4cm subpleural mass in the posterobasal segment of the RLL showing central low attenuation. The mass is supplied by the vessel from the descending aorta.

- Brief Review
- Distinguishing an intrapulmonary sequestration from extrapulmonary sequestration is difficult using plain radiography. Intrapulmonary lesions tend to be heterogeneous and are not well defined. Extrapulmonary masses are usually observed as solid, well defined, and retrocardiac.
Intrapulmonary sequestrations are the most common form, and 60% of these are found in the posterior basal segment of the left lower lobe. Overall, 98% occur in the lower lobes. Bilateral involvement is uncommon. About 10% of cases may be associated with other congenital anomalies. A case of intrapulmonary sequestration associated with a bronchogenic cyst has been reported.Extrapulmonary sequestrations occur on the left in 95% of cases. Of these, 75% are found in the costophrenic sulcus on the left side. They may also be found in the mediastinum, pericardium, and within or below the diaphragm.They are associated with other congenital malformations in more than 50% of cases, such as congenital diaphragmatic hernias, congenital cystic adenomatoid malformation (CCAM) type II (hybrid lesions), and congenital heart disease.
