(A,B) Axial (A) and sagittal (B) ultrasound images of the chest demonstrate a large right chest mass containing multiple macro- and microcysts displacing the heart to the left (arrow) and everting the diaphragm inferiorly.
(C) Axial MRI demonstrates marked deviation of the heart to the left (arrow).
(D) Coronal MRI demonstrates minimal residual normal lung in the left upper lobe (arrow). No systemic feeding vessel and no hydrops appreciated. CVR was 2.4, consistent with high risk for hydrops.
