Uterine infarction in a patient with uterine adenomyosis following biochemical pregnancy / 대한생식의학회지

Adenomyosis is a common gynecological disorder characterized by the presence of endometrial glands and stroma deep within the myometrium associated with myometrial hypertrophy and hyperplasia. Focal uterine infarction after IVF-ET in a patient with adenomyosis following biochemical pregnancy has not been previously reported, although it occurs after uterine artery embolization in order to control symptoms caused by fibroids or adenomyosis. We report a case of a nulliparous woman who had uterine adenomyosis presenting with fever, pelvic pain and biochemical abortion after undergoing an IVF-ET procedure and the detection of a slightly elevated serum hCG. Focal uterine infarction was suspected after a pelvic magnetic resonance imaging demonstrated preserved myometrium between the endometrial cavity and inner margin of the necrotic myometrium. This case demonstrates that focal uterine infarction should be considered in the differential diagnosis of acute abdominal pain, vaginal bleeding and infectious signs in women experiencing biochemical abortion after an IVF-ET procedure.

Ultrasonographic Diagnosis of a Uterine Fusion Anomaly Associated with Neonates with Unilateral, Ectopic, Multicystic, Dysplastic Kidney

PURPOSE: The purpose of this paper is to reinforce the necessity of careful ultrasonographic evaluation of the uterus to detect uterine fusion anomaly in female neonates who were detected as having a unilateral, ectopic, multicystic, dysplastic kidney (MCDK) on fetal US. MATERIALS AND METHODS: We detected eight unilateral ectopic MCDK on fetal US of second trimester and neonatal ultrasonography between October 2003 and February 2009; neonatal US were taken at 2 to 10 days after birth for the initial evaluation of MCDK. Uterine fusion anomaly, vaginal obstruction and other associated urogenital anomalies were evaluated by neonatal US. RESULTS: Four of eight female neonates with unilateral ectopic MCDK showed a double uterus on neonatal US. They all showed hemivaginal fluid collection. Obstruction of the hemivagina and vaginal septum were depicted in two cases. A perivaginal cyst was seen in three cases, and in two cases the cyst was connected with the vaginal cavity. An ipsilateral perivaginal tubular structure was seen in one case, which was indicative of a ureteral remnant. There was no associated anomaly in the contralateral kidney except for a tiny cortical cyst in one case. CONCLUSION: The careful ultrasonographic evaluation of the uterus is important in female neonates who showed the ectopic MCDK on fetal US. In addition, it may help to detect the fusion anomaly that is otherwise difficult to detect on fetal US and to devise a treatment plan to prevent upcoming complications.

Prenatal diagnosis of achondrogenesis type II: A case report / 대한주산의학회잡지

We present a case of achondrogenesis type II demonstrating increased nuchal translucency on the first trimester ultrasound, which was confirmed in the second trimester ultrasound. Achondrogenesis type II is characterized by micromelia, varied ossification of spine, an enlarged calvarium with normal ossification, variable shortening of the ribs, and lack of rib fractures. In this case, ultrasonographic examination in the second trimester revealed a normally ossified cranium with relatively short long bones and a mildly protuberant abdomen due to small thorax and scanty ossified vertebral bodies. All these findings were compatible with the diagnosis of achondrogenesis type II. We further confirmed the diagnosis of achondrogenesis type II with postmortem radiographic examination.

Ultrasonographic Findings of Fetal Congenital Intracranial Teratoma

PURPOSE: To evaluate the sonographic findings of fetal congenital intracranial teratoma. MATERIALS AND METHODS: From 1994 to 2002, of the 11 fetuses which had been diagnosed with fetal intracranial tumors after second level fetal ultrasonography, the six that were confirmed after autopsy as congenital intracranial teratomas were included in our study. The sonographic findings, including size, homogeneity, echogenicity compared with surrounding normal brain tissues, cystic components, and tumor related calcification, were retrospectively evaluated. RESULTS: The incidence of fetal congenital intracranial teratoma out of all fetal intracranial tumors was 54.5% (6 of 11 cases) during the 8-year period. The mean mass size was 7.4 cm (3.0-15.0 cm). Two thirds of (4/6) of the teratoma cases showed high echogenicity compared with normal brain tissues, and two thirds (4/6) showed heterogeneous echogenicity. Four teratoma cases (67%) showed cysts in the mass with a mean size of 1.9cm. One third (2/6) showed calcifications within the tumor. Out of the six cases, two had oropharyngeal teratoma with extension into the intracranial portion (so called epignathus) and showed homogenous mass without any cysts or calcifications. CONCLUSION: The typical sonographic appearance of intracranial teratoma was a heterogeneous, hyperechoic mass with cysts. In the epignathus cases, the sonographic appearances differed somewhat from the others. An understanding of the sonographic findings of fetal intracranial teratoma will help in the timely counseling of the parents and in obstetric decision making.
