The first-trimester ultrasound screening at 12 weeks and 4 days of gestation revealed a hyperechoic aspect of the entire right lung, which led us to suspect a unilateral pulmonary pathology (Figure 1A, 1B). The left lung was compressed by mass effect (27x14 mm) (Figure 1C, 1D).
(A) Right lung (49 g) with hypertrophic lower lobe and normal left lung. (B) Histological appearance of right lung tissue with microcystic lesions. (C) Histological appearance of normal left lung tissue.
