[Congenital mesoblastic nephroma (Bolande's tumor). Prenatal diagnosis].

The authors report a new case of the antenatal ultrasound diagnosis of a congenital mesoblastic nephroma (also called Bolande's tumor) at 33 weeks of amenorrhea. This tumor was found to be associated with acute hydramnios involving premature labor and fetal death by respiratory embarrassment. Congenital mesoblastic nephroma is a very rare entity but is the predominant renal neoplasm in the immediate neonate period. The differential diagnosis between Bolande's tumor and nephroblastoma (Wilm's tumor) is now clear since histopathological features have been precisely described by Bolande. Clinical and pathological features of the renal disease are discussed. The prognosis is excellent for most cases requiring only surgical treatment (nephrectomy).

[Fetal blood sampling for karyotype using echoguided puncture of the cord. Study of 103 pregnancies].

Subcutaneous ultrasound guided puncture of the umbilical cord was carried out in order to obtain samples of blood in 103 fetuses. This was done to get the result of the karyotype quickly, i.e. in 72 hours. The indications were for diagnosis, particularly of malformations (63 cases) or intra-uterine growth retardation (24 cases). A small proportion of the indications were those for failures to carry out amniocentesis early or for checking on mosaics that were obtained after the culture of amniotic fluid cells. In 88% of the cases it was possible to obtain a karyotype and the results were checked with the sex of the fetus and the karyotype that had been obtained from amniocentesis. There were 11 abnormalities diagnosed. The chief indication of chromosome abnormality is fetal malformation. Because the result are obtained so quickly cordocentesis should replace late amniocentesis, at present when looking for fetal abnormalities.

Magnetic resonance imaging of sexual intercourse: initial experience.

The objective of this study was to investigate sexual intercourse with magnetic resonance imaging (MRI). A volunteer couple (30 year-old male, 27-year-old female) with a normal sex life, had face-to-face sexual intercourse (reversed missionary position) under MRI. Static and dynamic T2-weighted sagittal sequencies were acquired on the midline before and during vaginal penetration. In this position, before penetration, the vagina was parallel to the pubococcygeal line and had normal anterior convexity. After penetration, accentuation of the vaginal convexity was observed, produced by the penile gland reaching the anterior cul-de-sac and contact with the anterior vaginal wall. The posterior bladder wall was pushed forward and upward, the uterus upward and backward. In this initial experience, we observed a preferential contact of the penis in erection with the anterior vaginal wall and the anterior cul-de-sac in the face-to-face sexual position. MRI allows a noninvasive assessment of sexual intercourse.
