BACKGROUND
Congenital orbital teratoma is relatively rare, and few reports of prenatal ultrasound findings in such cases have been published.
CASE PRESENTATION
A rare case of congenital orbital teratoma at 24 + 2 weeks of gestation was previously diagnosed as microphthalmia, noting how orbital teratoma without proptosis is different from microphthalmia, retinoblastoma and intracranial teratoma. Ultrasound examination, analysis of gross specimens, and histopathological evaluation confirmed the diagnosis of orbital teratoma.
CONCLUSION
Prenatal ultrasound examination is useful for diagnosis and differential diagnosis of congenital orbital teratoma.
背景
先天性眼眶畸胎瘤较为罕见，此类病例的产前超声表现鲜有报道。
病例介绍
此前，我们在 24+2 孕周时诊断了一例罕见的先天性眼眶畸胎瘤病例，该病例最初被诊断为小眼球，提示无眼球突出的眼眶畸胎瘤与小眼球、视网膜母细胞瘤和颅内畸胎瘤不同。超声检查、大体标本分析和组织病理学评估均证实了眼眶畸胎瘤的诊断。
结论
产前超声检查有助于先天性眼眶畸胎瘤的诊断和鉴别诊断。
