A 12 Week Fetus with Anophthalmia, Limb Anomalies and Infratemporal Teratoma.

ABSTRACT

Background: Microphthalmia is a rare autosomal recessive condition commonly known as Waardenburg anophthalmia syndrome (WAS) or oculo-acromal formation syndrome (MIM#206920). Case Description Here, we report the case of a woman whose fetal ultrasonography at 12 weeks of pregnancy revealed multiple fetal abnormalities. These included the absence of the left upper limb, an unclear display of the right orbit, a visible maxillary space, and a round, echoless appearance measuring 4 mm in diameter in the middle of the forehead. There was also a significant echo in the sac wall. The possibility of a frontal meningocele or a proboscis-like nose was considered. The fetus was delivered with absence of the left upper limb, absence of the right eye, a cleft lip on the right side, and a milky white sac with a diameter of 5 mm on the forehead after the pregnancy was terminated at the hospital. Pathological investigation revealed a mature cystic teratoma. The conclusion was microphthalmia with limb anomalies (MLA) after missing limbs, absence of eyes, and cleft lip were input into the Online Mendelian Inheritance in Man database. The case was diagnosed with fetal microphthalmia with limb anomalies and an interfrontal teratoma. Conclusion: In this case, the entire exon analysis was not conducted, and as a result, the final diagnosis remains unclear. Based exclusively on the phenotype of the induced fetus, MLA was diagnosed. It is proposed that cases satisfying the requirements for a pathological diagnosis should undergo a pathological examination to establish a definitive diagnosis.
