CONGENITAL CYSTIC LUNG DISEASE: PRENATAL ULTRASOUND AND POSTNATAL MULTIDETECTOR COMPUTER TOMOGRAPHY EVALUATION. CORRELATION WITH SURGICAL AND PATHOLOGICAL DATA

Purpose. To evaluate the diagnostic accuracy of postnatal MDCT compared with
prenatal US, surgical findings, and histology, in 33 patients with Congenital Cystic Lung
Disease.
Methods. Thirty-three patients, 17 males and 16 females, were evaluated by MDCT. 27
of these patients underwent prenatal US between week 18 and 22, and between week
32 to 35 of gestation. Lung lobectomy, segmentectomy, atypical resection, lesion
resection were performed in 31 patients and surgical specimens were analysed.
Results. Prenatal US and MDCT correctly diagnosed 76.9% and 94% of the lesions,
respectively. Disagreement occurred in 6 lesions with PUS, and in 2 lesions with
MDCT. No statistically significant differences were observed between the two techniques (p=0.122).
Conclusions. As most of surgeons consider the surgical resection of these lesions
mandatory, our study underscores the essential role of imaging, in particular Computed
Tomography, in providing invaluable preoperative information on Congenital Cystic
Lung Diseases recognized in uterus.
