“…3D ultrasonography could facilitate prenatal diagnosis and help in planning delivery, through the various 3D software programs such as the surface-rendering mode, the "multislice" view, the "reverse face" view, and tomographic mode [ 4 , 5 , 6 ]. Reconstructed images from the 3D volume data can provide information about the size, location, composition, and extension of the tumor.…”

“…The tumor fills the oral cavity and hence is associated with a high mortality rate owing to severe airway obstruction, especially in the neonatal period [ 1 , 2 , 3 ]. Usually, this tumor was detected in late second trimester or third trimester [ 2 , 3 ], but technical developments in three-dimensional (3D) ultrasonography and magnetic resonance imaging (MRI) have enabled early diagnosis and detailed characterization of the tumor [ 4 , 5 , 6 ]. Herein, we present a case of epignathus affecting 1 fetus in a twin pregnancy.…”

Prenatal diagnosis of epignathus with multiple malformations in one fetus of a twin pregnancy using three-dimensional ultrasonography and magnetic resonance imaging

et al. 2015

Epignathus is an extremely rare type of congenital teratoma arising in the oral cavity. Although it is a benign tumor, it is associated with high mortality and morbidity rates because of severe airway obstruction and other malformations. We present a case of epignathus affecting one fetus in a twin pregnancy. The tumor was associated with multiple congenital malformations including cleft palate, bifid tongue, bifid uvula, congenital heart defect, and bilateral inguinal hernias. The diagnostic value of three-dimensional ultrasonography and magnetic resonance imaging was explored with respect to antenatal counseling and peripartum management.

“…The majority of the cases described in the literature had earlier diagnoses at the start of the second trimester (Gull et al, 1999; Clement et al, 2001; Chen et al, 2003). There is a single case in the literature that was diagnosed in the first trimester, in which a fetus of gestational age 12 weeks was seen to present a semilobulated growth in the sagittal plane that protruded through the oral cavity and measured 11 × 18 × 9 mm (Dar et al, 2009). Prenatal diagnoses are frequently made at a late stage in developing countries like Brazil, where pregnant women start their prenatal follow-up late and there are difficulties in accomplishing subsidiary examinations like 2DUS and in referring cases of suspected malformations to tertiary-level clinics.…”

Epignathus teratomas are rare tumors that originate in the region of the palate or pharynx and are known as Rathke pouch. They may be associated with other malformations such as a cleft palate and bifid tongue or nose. The prenatal diagnosis can be established by two-dimensional ultrasonography showing a heterogeneous mass protruding through the mouth of the fetus. The three-dimensional ultrasonography in rendering mode permits better understanding of this anomaly by the parents, facilitating the counseling. The importance of prenatal diagnosis lies in the fact that this tumor may obstruct the airways, thus leading to death at birth due to respiratory insufficiency. We report a case of prenatal diagnosis of epignathus teratoma in the 30th week of pregnancy by two-dimensional ultrasonography. We focus on the importance of three-dimensional ultrasonography in rendering mode for demonstrating the spatial relationships of the tumor with the oral cavity and provide correlations between the ultrasound images and the anatomopathological findings.

“…The 3D images of the oral teratomas presented in these reports were all limited to showing the mass in the surface-rendering mode. [21][22][23][24][25][26] As demonstrated in this report, other 3D techniques can provide potentially useful information in the assessment of fetal oral masses.…”

Prenatal 3-Dimensional Imaging Techniques in the Sonographic Evaluation of an Oral Mass

Historically, published reports of 3-dimensional (3D) sonographic evaluation of fetal oral masses have been limited to the surface-rendering mode. This report demonstrates the clinical potential of various 3D imaging techniques in the evaluation of fetal epignathus. A comparison is made among the images generated from 3D data sets, postnatal magnetic resonance imaging and computed tomographic scans, and the excised surgical specimen. The diagnostic value and limitations of several 3D imaging techniques in the evaluation of an oral mass are explored.
