We present eight cases of suprarenal masses detected sonographically in fetuses of 20-41 weeks. The appearances of the masses included hyperechoic (n = 2, both pulmonary sequestrations), solid isoechoic (n = 1, a neuroblastoma), purely cystic (n = 3, two neuroblastomas, one enteric cyst) and mixed or complex (n = 2, one neuroblastoma and one renal cyst). Three of the fetuses with neuroblastoma had normal scans in the second trimester, and in all four the neuroblastomas were detected after 36 weeks. This study demonstrates the differential diagnosis of suprarenal masses in fetuses. Neuroblastomas can have a solid, purely cystic or complex sonographic appearance. Although not all suprarenal masses are neuroblastomas, the newborn with a prenatally detected suprarenal mass should be evaluated for the possibility of a neuroblastoma, since early diagnosis of this malignancy can be curative.
我们报告了8例在孕20 - 41周胎儿中经超声检查发现的肾上腺肿块。肿块表现包括高回声（2例，均为肺隔离症）、实性等回声（1例，神经母细胞瘤）、纯囊性（3例，2例神经母细胞瘤，1例肠囊肿）以及混合性或复杂性（2例，1例神经母细胞瘤和1例肾囊肿）。3例患有神经母细胞瘤的胎儿在孕中期扫描正常，所有4例神经母细胞瘤均在36周后被发现。本研究展示了胎儿肾上腺肿块的鉴别诊断。神经母细胞瘤在超声检查中可表现为实性、纯囊性或复杂性。虽然并非所有肾上腺肿块都是神经母细胞瘤，但对于产前检测到肾上腺肿块的新生儿，应评估其患神经母细胞瘤的可能性，因为早期诊断这种恶性肿瘤可能治愈。
