A pseudoaneurysm should be considered in unclear cases of postpartum hemorrhage.
Background. We experienced a rare case of a pregnant woman with Klippel-Trénaunay syndrome complicated with diffuse venous malformation of the uterus. This is the first report on the usefulness of dynamic contrast-enhanced-MRI for the diagnosis of diffuse venous malformation of the uterus. Case Presentation. A 23-year-old woman presented with convulsions and talipes equinus position of both lower limbs at 11 weeks of gestation. At 27 weeks, ultrasonography demonstrated tubular echolucent spaces throughout the myometrium. Dynamic MRI at 37 weeks revealed that the myometrial lesion was enhanced slowly and showed homogeneous enhancement even on a 10 min delayed image. Taken together with unilateral foot hypertrophy, varices, and port-wine stain, the patient was diagnosed as having Klippel-Trénaunay syndrome complicated with diffuse venous malformation of the pregnant uterus. The patient underwent elective cesarean section because of severe dystonia. The lower uterine segment was thickened and heavy venous blood flow was observed at the incision. Histological diagnosis of the myometrial biopsy specimen was venous malformation. Conclusions. Both diffuse venous malformation and Klippel-Trénaunay syndrome during pregnancy can involve considerable complications, in particular, massive bleeding during labor. Women who suffer from this syndrome should be advised about the risk of complications of pregnancy.
Massive subchorionic thrombohematoma (MST), termed Breus’ mole, is a rare condition in which a large maternal blood clot separates the chorionic plate from the villous chorion. Common complications of MST include fetal growth restriction, preeclampsia, and intrauterine fetal death. Here, we present a case of a 17-year-old Japanese woman referred to our institution at 21 weeks of gestation. Ultrasound examination revealed a large placental mass with mixed high and low echogenicity measuring approximately 7.6 cm in thickness. Doppler examination showed absence of end-diastolic velocity of the umbilical artery. At 22 weeks of gestation, the patient had a stillbirth weighing 138g. The placenta weighed 502 g and was 8 cm thick, and the total blood loss was 270 g. Macroscopic examination revealed that a subchorionic blood clot measuring 12 cm × 5 cm covered a large portion of the placenta with well-defined margins on the fetal surface. Microscopic examination revealed an intervillous hematoma and fibrinous deposits directly beneath the chorionic plate with adjacent compressive effects. Based on these findings, MST was diagnosed. Because MST is rare, it must be considered in the differential diagnosis of parental conditions. Magnetic resonance imaging can be optimal for diagnosing MST when ultrasound diagnosis is difficult.
Sigmoid volvulus requires urgent treatment, and it is particularly rare among pregnant women without a history of laparotomy. A delay in diagnosis may lead to serious consequences for the mother and fetus, and a rapid diagnosis and treatment in this setting is essential. The patient was a 19-year-old primiparous woman. She complained of repeated exacerbations and remissions of abrupt lower abdominal pain for the past 2 days and was transported to our hospital at 33 weeks of gestation. Ultrasonography revealed no placental thickening, and maternal bowel dilation was difficult to identify. Plain abdominal X-ray showed a dilated colon on the left side of the abdomen. Contrast-enhanced CT scan of the abdomen revealed a volvulus on the dorsal side of the uterus. The proximal end of the transverse to sigmoid colon was markedly dilated, and the distal end was collapsed. The elevated lactate level on blood gas analysis suggested intestinal ischemia. She was suspected of having a sigmoid volvulus at 33 weeks and 3 days of gestation. We decided to perform a cesarean section to secure the operative field for an intestinal resection following delivery. A male weighing 1840 g with Apgar scores 8/8 was delivered. The sigmoid colon was approximately 80 cm in length. A 360-degree clockwise rotation of was observed with a very distended but viable sigmoid loop. Following reduction of the volvulus, the sigmoid colon was fixed to the left side of the peritoneum. The mother had an uneventful postoperative course, and the infant was discharged without any sequelae. This case demonstrates two important lessons. First, sigmoid volvulus can occur in pregnant women even if they never had a laparotomy. Second, abdominal contrast-enhanced CT is useful for rapid diagnostic and treatment decisions relative to this pathology.
Two types of congenital bronchial atresia (proximal and peripheral) have been classified. We report two cases of peripheral bronchial atresia diagnosed by prenatal ultrasonography (US) and magnetic resonance imaging (MRI). Evaluating an enlarged lung mass that is homogeneously hyperechoic on US and hyperintense on T2-weighted MRI can help in determining whether bronchial atresia is present. Proximal type is suggested when a dilated main bronchus is observed as a tubule structure of an involved lung hilum. In our cases, T2-weighted MRI revealed homogeneously hyperintense lung lesion with decreased signal intensity of adjacent lobe, flattening diaphragm, and mediastinal shift. Dilatation of the main bronchus was not observed and the opposite lung was normal in appearance. These findings were explained by secondary compression due to enlargement of the involved lung. The preservation of vascular structure and the retained normal shape, though enlarged, in the affected lobe were observed, which demonstrated undisrupted pulmonary architecture of the lobe. Thus, congenital cystic adenomatoid malformation was excluded because pulmonary architecture was relatively preserved. Finally, presumed diagnoses of the peripheral bronchial atresia were made and confirmed by postnatal chest computed tomography.
