[size=20px]A 15 month-old boy presents with a cough. A chest x-ray and subsequent CT scan demonstrate a cystic mass in the right lower lobe. Two prenatal ultrasounds showed no evidence of a lung lesion. The most appropriate management is:

A Bronchoscopy

B Repeat chest x-ray in three months

C Right lower lobectomy

D Thoracoscopic wedge resection of cyst

E Cyst aspiration and sclerosis[/size]

[size=20px]A 3 month-old term infant was diagnosed prenatally with a congenital lung lesion. She had no respiratory issues postnatally and remains well. She recently underwent a CT scan of the chest and is in your clinic to review the results. Which features on history and imaging are associated with an increased risk of malignancy?

A Size less than 3 cm

B Macrocystic lung lesion

C Prenatal detection

D Presence of a systemic feeding vessel

E All of the above[/size]

[size=20px]A 5-month-old girl is being seen in your clinic for a right lower lobe cystic lung mass. She had a CXR performed for a chronic cough and the lesion was seen. Chest CT scan was performed and shows a macrocystic 4 cm lesion in the right lower lobe, with question of a feeding vessel. Her mother had serial prenatal ultrasounds for placental position and the lesion had not been seen. In this child’s history, which factor is most concerning for possible malignancy?

A Absence of lesion on prenatal ultrasound

B Location of lesion

C Presence of systemic feeding vessel

D Size of lesion[/size]

[size=20px]A previously healthy six month male infant presents with cough and fever. A chest radiograph reveals bronchiolitic changes and a large right lung cyst. After treatment, a follow up CXR 6 weeks later is normal except for a persistent cyst, and chest CT scan demonstrates a multilocular, 5 cm peripheral lung cyst in the right lower lobe, without air fluid levels or a feeding vessel. Prenatal ultrasounds were normal.

The next step in the care of this child should be:

A Bronchoscopy

B Sweat test to exclude cystic fibrosis

C Thoracoscopic or open right lower lobectomy

D B-Catenin gene analysis

E Repeat CXR in 3 months[/size]
