The clinical data, ultrasonographic features, treatments, and prognoses of the fetuses were analyzed. Postnatal diagnoses were made using computed tomography (CT), magnetic resonance imaging, and surgical resection.Results: Of the 36 fetuses, 10 were diagnosed with adrenal hematomas, eight with adrenal neuroblastomas, seven with adrenal cysts, seven with subphrenic pulmonary sequestration, and four with adrenal teratomas. The accuracy of prenatal diagnosis was highest in those with adrenal cysts and subphrenic pulmonary sequestration, with the accuracy being 85.7% for both conditions. The mean gestational age at first detection of subphrenic pulmonary sequestration was 22.5 ± 3.1 weeks, which was significantly lower than that of other diagnoses (P < 0.05), and the mean diameter of adrenal cysts was 15.1 ± 4.2 mm, which was significantly smaller than that of other lesions (P < 0.05). All newborns with adrenal teratomas and neuroblastomas were treated surgically. Five of the seven patients with subphrenic pulmonary sequestration and three of the seven patients with cysts were also treated surgically. Follow-ups of the remaining cases were carried out by enhanced CT examination, and the prognoses were good.Conclusion: Prenatal ultrasonography can help differentiate between different types of fetal adrenal space-occupying lesions, and there is a high coincidence rate between the diagnosis of adrenal cysts and subphrenic pulmonary sequestration.Keywords: ultrasonography, prenatal diagnosis, suprarenal space-occupying lesion, fetus mass
