Fetal congenital cystic adenomatoid malformation. PELVIS:UTERUS, ADNEXA: Gravid uterus with one fetus in vertex position facing posteriorly. The placenta is along the posterior fundus and body of the endometrial canal. No evidence of placenta previa or accreta. The cervix appears closed. Normal volume amniotic fluid.The neural axis is unremarkable.The heart apex and stomach are left-sided. Note is made of several cyst like structures in the left lung base with the largest measuring 1.5 x 1.0 cm and 1.1 x 0.8 cm. No obvious communication between the cystic structures is demonstrable. The extent of the subtle signal abnormality associated with these larger cysts measures approximately 4.1 x 2.6 cm in the sagittal plane (series 1 301/15) and approximately 3.3 x 2.9 cm in the coronal plane (series 1 101/12). No findings to suggest an intralobular sequestration such as vascular supply from the systemic circulation. The diaphragm appears intact.Unremarkable kidneys bladder bowel liver gallbladder and spleen. BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
Findings compatible with stated history of congenital pulmonary adenomatoid malformation with several macrocystic components visualized on MRI. The extent of the left lower lobe signal abnormality measures approximately 4.1 x 2.6 cm which includes the smaller cystic components. No specific findings to suggest a hybrid/combined-type CCAM and intralobar sequestration lesion.No additional fetal abnormality is identified.
