Bilateral femoral neck fractures resulting from pregnancy-associated osteoporosis showed bone marrow edema on magnetic resonance imaging.

Femoral neck fractures resulting from pregnancy-associated osteoporosis is a rare condition. Herein, we report an undoubted case of pregnancy-associated osteoporosis in a 38-year-old primiparous patient with pre-existing anorexia nervosa who suffered bilateral femoral neck fractures in the third trimester and early post-partum period. Magnetic resonance imaging revealed femoral neck fractures as well as diffuse marrow edema involving both femoral heads, which are considered under ordinary circumstances as characteristic imaging findings of transient osteoporosis of the hip. Based on our experience, we propose that pregnancy-associated osteoporosis might be present in femoral neck fractures attributed to transient osteoporosis of the hip in pregnancy. Conversely, bone status should be carefully and accurately estimated in cases of potential transient osteoporosis of the hip in pregnancy to reduce future fracture risk.

Prenatal diagnosis of sirenomelia in the late second trimester with three-dimensional helical computed tomography.

Sirenomelia is a rare congenital syndrome that is characterized by the anomalous development of the caudal region of the body. The anomalies include bilateral renal agenesis or dysgenesis and the absence of the sacrum and other vertebral defects. Sirenomelia is also known as "mermaid syndrome," because of the one lower extremity. It is usually associated with severe oligohydramnios, and its prognosis is very poor due to pulmonary hypoplasia that is caused by severe oligohydramnios. The patient referred to our hospital at the gestational age of 27 weeks with fetal growth restriction and oligohydramnios. The estimated fetal body weight was 970 g (-4.9 S.D.). We could identify only one-side extremities, and could not identify kidneys by ultrasound examination. Because a single lower extremity and severe oligohydramnios are characteristics of the sirenomelia, we suspected sirenomelia. However, it could not be confirmed by ultrasound examination because of oligohydramnios. Therefore, we performed three-dimensional helical computed tomography (3D-CT), which is more accurate than ultrasound examinations for prenatal diagnosis of skeletal abnormalities. 3D-CT revealed an only one lower extremity. At 36 weeks and 5 days of gestation, the woman went into spontaneous labor and delivered an infant weighing 870 g. The infant has a single upper extremity and a single lower extremity. We provided supportive care for the neonate, who however died 1 hour 36 minutes after birth from severe respiratory distress. In summary, we report the correct diagnosis of sirenomelia with 3D-CT in the late second trimester.

An unusual presentation of usual-type endocervical adenocarcinoma with lobular endocervical glandular hyperplasia: A case report.

Uterine cervical hematoma is rare. A 51-year-old woman underwent pelvic magnetic resonance imaging (MRI) for uterine tumor survey. A large hematoma with cystic and solid lesions was observed in the uterine cervix. Follow-up MRI after 5 days revealed that the hematoma had decreased in volume. Pathological examination after surgery suggested there was usual-type endocervical adenocarcinoma (UEA) in the lower cervix and lobular endocervical glandular hyperplasia (LEGH) in the upper cervix, along with the cervical hematoma. The findings of this case suggest that the uterine cervical hematoma was secondary to either UEA or LEGH.

Successful pregnancy after gonadotropin-releasing hormone analogue and hysteroscopic myomectomy in a woman with diffuse uterine leiomyomatosis.

We report a patient with diffuse uterine leiomyomatosis, who wished to become pregnant. We performed hysteroscopic myomectomy after treatment with nafarelin acetate for 6 months. The patient conceived spontaneously soon after hysteroscopic myomectomy, and delivered a 2,798-g healthy baby.

Effectiveness of antiadhesion barriers in preventing adhesion after myomectomy in patients with uterine leiomyoma.

BACKGROUND: Myomectomy often causes adhesion formation and decreases subsequent fertility. The purpose of the present study was to evaluate the effectiveness of several antiadhesion barrier materials in preventing adhesion after myomectomy. METHODS: We prospectively classified 63 women undergoing myomectomy alone into four groups according to the type of antiadhesion material used: Hyaluronic acid-carboxymethylcellulose film (Seprafilm) (n = 21, Group 1), Dextran 40 (10% Dextran 40 Low Injection) (n = 17, Group 2), factor 13 with fibrinogen (Beriplast) (n = 12, Group 3) and control (n = 13, Group 4). We performed early second-look laparoscopy after the seventh post-operative day in all patients and examined adhesion formation in the abdominal cavity. The incidence of adnexal adhesions was evaluated according to the American Fertility Association (AFS) adhesion score. RESULTS: The incidence of uterine adhesion was 14.3% in Group 1, 70.6% in Group 2, 75.0% in Group 3 and 76.9% in Group 4. Adhesion formation in Group 1 was significantly less than that in Group 2 (p = 0.0004), Group 3 (p = 0.0005) and Group 4 (p = 0.0003). The incidence of peritoneal adhesion was 14.3% in Group 1, 29.4% in Group 2, 41.6% in Group 3 and 69.2% in Group 4. Adhesion formation in Group 1 was significantly less than that in Group 4 (p = 0.001). AFS scores in Groups 1-4 were 0.38+/-1.02, 4.58 +/- 7.02, 0.83 +/- 1.99 and 8.53 +/- 8.79 (mean +/- S.D.), respectively. Group 1 had the lowest AFS score and the difference between Group 1 and Group 4 was significant (p < 0.0001). The AFS score in Group 3 was also significantly less than that of Group 4 (p = 0.0009). CONCLUSION: Seprafilm was highly effective and was superior to the other antiadhesion materials tested in preventing uterine adhesions after myomectomy.

In utero diagnosis of an aneurysm of the vein of Galen causing hydrocephalus and heart failure.

A prenatally diagnosed aneurysm of the vein of Galen was presented in the fetus of a patient referred to our hospital at 31 weeks of gestation. Ultrasonography demonstrated polyhydramnios, cardiomegaly, dilatation of the right atrium and superior vena cava, tricuspid valve regurgitation, hydrocephalus, and a large hypoechoic mass with blood flow in the suboccipital region. Skin edema was shown thereafter. A 3262-g male was delivered by cesarean at 35 weeks of gestation. Computed tomography imaging demonstrated a large mass in the suboccipital region, after which thrombocytopenia appeared and the neonate died at 18 days of age.
