Peer Review Status: Internally Peer Reviewed
The patient was a 1 month old male who was noted to have increased respiratory rates and contractions.
Clinical Physical Exam:
Clinical Differential Diagnosis:
Infection versus lung lesion.
Nuclear medicine, chest CT exam, and chest films showed a lesion in the right lung.
Images 1 and 2
Imaging Differential Diagnosis:
Congenital lobar emphysema versus cystic adenomatoid malformation
Two weeks after the chest CT exam the patient had an elective thoracotomy. The right middle lobe was emphysematous and a right middle lobectomy was performed.
The mass was 10 x 7 x 3 cm in size. Dysplastic lung parenchyma with emphysematous changes consistent with lobar emphysema and features of polyalveolar lobe were found. Pathological Diagnosis: Congenital Lobar Emphysema, Right Middle Lobe
Follow-up and Prognosis:
The patient had an uncomplicated post-operative course. A routine chest film obtained two months postoperatively suggested a right upper quadrant calcification, and an ultrasound was performed to rule out neuroblastoma and was negative.
