背景:胎儿超声检查是妊娠随访的常规部分,轨道结构的检查也是常规评估的一部分。尽管眼眶发育异常在新生儿期很常见,在子宫内的诊断并不常见。据我们所知,文献报道了三例诊断为先天性眼眶表皮囊肿的病例,其中两人有胎儿影像学检查结果。在这篇文章中,我们介绍了1例胎儿期诊断为眼眶囊肿,新生儿期组织病理学诊断为表皮囊肿的产前影像学表现。
方法:一名25岁女性在妊娠22周时进行超声检查。引起眼球突出的35x45毫米囊性病变,没有固体成分和血管,在左眼眶观察到视神经周围并导致视神经变薄。在胎儿磁共振成像(MRI)中,眶内囊性病变,在T2W图像上是高强度的,在T1W图像上是低信号,与颅内结构没有关系,也没有固体成分。病人的病变,采取多学科方法,出生后的计算机断层扫描(CT)和磁共振成像(MRI)显示类似。随后,病人接受了保球手术,病理诊断为表皮囊肿。
结论:眼眶表皮囊肿很少见,胎儿期的检测甚至更罕见。在胎儿和新生儿期引起眼球突出的眼眶囊性病变的鉴别诊断中应考虑。
Fetal ultrasonographic evaluation is a routine part of pregnancy follow-up, and examination of orbital structures is also part of the routine evaluation. Although orbital developmental anomalies are common in the neonatal period, diagnosis in the intrauterine period is not common. To our knowledge, three cases with a diagnosis of congenital orbital epidermal cysts have been reported in the literature, and two of them had fetal imaging findings. In this article, we present the prepostnatal imaging findings of a
case diagnosed with orbital cyst in the fetal period and histopathologically diagnosed as epidermal cyst in the neonatal period.
A 25-year-old woman applied for ultrasonography (USG) examination at 22 weeks of gestation. A 35x45 mm cystic lesion causing proptosis, without solid component and vascularity, surrounding the optic nerve and causing its thinning was observed in the left orbit. In fetal magnetic resonance imaging (MRI), the intraorbital cystic lesion, which was hyperintense on T2W images and hypointense on T1W images, had no relationship with intracranial structures and no solid component. The lesion of the patient, followed up with a multidisciplinary approach, was shown similarly with computed tomography (CT) and magnetic resonance imaging (MRI) in the postnatal period. Subsequently, the patient underwent globe-sparing surgery, and the pathological diagnosis was made as the epidermal cyst.
Orbital epidermal cysts are rarely seen, and detection in the fetal period is even rarer. It should be considered in the differential diagnosis of orbital cystic lesions that cause proptosis in fetal and neonatal periods.
