Prenatal Diagnosis of Oral Teratoma by Ultrasound.

A pregnant woman had a normal second-trimester anatomic survey at 22 weeks gestation. She was revealed to have a fetal oral mass with polyhydramnios and invisible stomach bubble by ultrasound at 28 weeks. A 50 mm × 36 mm × 42 mm, solid mass was found in the fetal mouth, filling the entire oral cavity. Fetal magnetic resonance imaging showed a homogeneous solid mass in the oral cavity compressing the hypopharynx. At 33 weeks, preterm labor occurred because of the continuation of increased amniotic fluid volume, and a female infant was vaginally delivered. The infant died shortly after tracheal intubation attempt failed. Autopsy confirmed the prenatal sonographic finding. The final pathologic diagnosis was oral immature teratoma. Our study indicates that although oral teratomas are rare, they are readily apparent at prenatal sonographic examinations. Respiratory compromise is the frequent complication of oral teratomas, which is associated with high perinatal mortality.

Retrospective analysis of prenatal ultrasound of children with Pompe disease.

OBJECTIVE: The aim of this retrospective study is to determine the prenatal ultrasound markers of patients diagnosed postnatally with infantile-onset Pompe disease (IOPD). MATERIALS AND METHODS: This is a retrospective study of cases with a postnatal diagnosis of IOPD during a 5-year period. The medical file of the patients with IOPD was reviewed, and data regarding especially pregnancy were collected. RESULTS: Second trimester fetal sonographic anatomical scan was performed in all 13 cases during pregnancy. Two cases (15.4%) were found to have a persistently open mouth at 23 weeks and 24 weeks, respectively. Serials follow-up ultrasound examinations demonstrated the same findings in the two cases. Third trimester ultrasound was also performed in all cases. Large heart was found in five cases (38.5%), and fetal echocardiography confirmed hypertrophic cardiomyopathy. CONCLUSION: Our results indicate that a mid-trimester open mouth and third-trimester hypertrophic cardiomyopathy are the prenatal findings associated with the disorder of IOPD.
