Successful surgical resection of intrapericardial extralobar pulmonary sequestration with congenital pulmonary adenomatoid malformation type II

Incidental finding - the discovery of a bronchopulmonary foregut malformation through investigations for Crohn's disease

Pulmonary sequestration (PMS) is a rare bronchopulmonary malformation. It has an incidence of between 0.15% to 1.7%. Likewise, cystic adenomatoid malformation (CCAM) is another relatively rare category of a bronchopulmonary malformation with a reported incidence of between 1 in 25,000 to 1 in 35,000. Moreover, a bronchopulmonary malformation with features allied to both of these forms is considered an even rarer entity. In general, bronchopulmonary malformations present with a range of non-specific symptoms. Radiological features can be non-specific yet distinctive when related to clinical features. Ultimately, definitive diagnosis depends upon histological assessment of lung tissue. We present an adult female with radiological features of both pulmonary sequestration and cystic adenomatoid malformation. This was an incidental finding unrelated to the patients presenting complaint. This case highlights the importance of using a structured and systematic approach when interpreting medical imagery.

Intrapericardial extralobar pulmonary sequestration detected as an intrathoracic cystic mass by using prenatal ultrasonography: case report and review of the literature

Intrapericardial extralobar pulmonary sequestration is a very rare congenital lung anomaly. We report a case of this condition, detected as an intrathoracic cystic lesion by using prenatal ultrasonography. The neonate was born at 38 weeks of gestation with no progression of the lesion and no respiratory or cardiac symptoms. Ultrasonography and computed tomography (CT) revealed a 40 × 17 × 17-mm intrapericardial lesion, composed of cystic components and a solid component. Intrapericardial extrapulmonary sequestration was suspected largely because CT showed a vague aberrant artery. At the age of 3 months, elective surgery was performed, and the postoperative course was uneventful.

Intradiaphragmatic hybrid lesion in an infant: case report

Hybrid lesions have elements of both congenital cystic adenomatoid malformation and bronchopulmonary sequestration. We report an unusual case of an infant treated for an intradiaphragmatic hybrid lesion. Although computed tomography remains the criterion standard imaging examination for planning the operation, the exact localization of such lesions may be discovered only at surgical exploration.
