Acute abdomen due to ovarian congestion: a fallopian tube accompanied by a paratubal cyst, coiling tightly round the ovary.

We experienced an unreported rare case with an adnexal mass causing severe acute abdomen during pregnancy. A 30‐year‐old Japanese pregnant woman was transported to our hospital for her right lower abdominal pain at 30 weeks of gestation. Magnetic resonance imaging and ultrasound demonstrated a cyst measuring 3–4 cm in diameter adjacent to the right ovary, and a parovarian cyst was considered to be the most probable diagnosis. We strongly suspected torsion of the ovarian pedicle or fallopian tube in conjunction with her clinical symptoms. Laparotomy revealed that the elongated right fallopian tube accompanied by a paratubal cyst was coiling tightly 2.5 times round the right ovary, causing apparent congestion and enlargement of the right ovary. Soon after we released the congested right ovary from the coiling of the fallopian tube, the congestion subsided. The postoperative course was favorable, and pregnancy and delivery were uneventful.

Prenatal ultrasound and magnetic resonance imaging findings of a hypovascular epignathus with a favorable prognosis

Epignathus of a fetus is an extremely rare type of an oropharyngeal teratoma that commonly arises from the palate and often grows in the prenatal period, leading to polyhydramnios due to difficulty in swallowing before birth and a high mortality due to the airway obstruction after birth. We report here a very rare case of a fetus with an epignathus decreasing in size naturally in the prenatal period with a favorable prognosis. In contrast to previously reported cases of epignathus that grew rapidly in the prenatal period, color Doppler fetal ultrasound showed a hypovascular tumor in our case. Moreover, histopathologic examination revealed an epignathus with necrotic areas inside. Based on our experience, a hypovascular epignathus demonstrated by color Doppler fetal ultrasound may be an indicator of a favorable prognosis.

P27.15: An applied Volume NT and VOCAL for measurement of the fetal heart

dimensional sagital view of the fetal front was performed to make the 3D reconstruction. Only one examiner obtained the anterior bâ by rendered mode. Correlation between gestational age (GA) and bâ was obtained by Pearson’s coefficient (r). Results: There was a weak linear correlation between GA and bâ (r = 0.05), however, between 18 and 24 weeks the bâ has ranged from 15.01 to 47.59 degrees. Percentiles from 5 to 95 are shown in table 1. The mean, median, SD, maximum and minimum values for each gestational age were calculated. Conclusions: Although no clear correlation between gestational age and angle values above the bregma, there are minimum and maximum values within the range 18–24 completed weeks of gestation. Such values may perhaps be adopted during the second trimester scan, seeking for early diagnosis of craniosynostosis. However, further studies are needed for more conclusive data.
