Abstract：
Fetal intracranial teratoma presents a rare and devastating diagnosis. Typically, this condition is first detected during routine prenatal ultrasounds, appearing as an irregular heterogeneous lesion. Further insights are gained through fetal magnetic resonance imaging (MRI), better characterizing the anomaly. The combination of these modalities provides detail-oriented high resolution MRI images, while follow-up ultrasounds capture dynamic growth changes, serving as a cost-effective and easily accessible adjunct. This fast-growing tumor leads to macrocephaly and ventriculomegaly, causing severe distortion of the brain parenchyma. Early detection is crucial for effective fetal management and preventing maternal complications. Unfortunately, treatment options are limited due to the tumor\'s aggressive nature, typically resulting in fetal demise shortly after birth. Here, we present the sonographic and MRI findings of a congenital intracranial teratoma, reaching massive proportions and replacing the entire cerebral hemisphere.
摘要：
胎儿颅内畸胎瘤是一种罕见且破坏性的诊断。通常,这种情况是在常规产前超声检查中首先检测到的，表现为不规则的异质性病变。通过胎儿磁共振成像（MRI）获得进一步的见解，更好地表征异常。这些模式的组合提供了面向细节的高分辨率MRI图像，而后续超声捕获动态生长变化，作为一个具有成本效益和容易获得的辅助服务。这种快速增长的肿瘤会导致大头畸形和脑室肿大，导致脑实质严重变形.早期发现对于有效的胎儿管理和预防母体并发症至关重要。不幸的是,由于肿瘤的侵袭性，治疗选择有限，通常导致胎儿出生后不久死亡。这里,我们介绍了先天性颅内畸胎瘤的超声和MRI表现，达到巨大的比例并取代整个大脑半球。
