Fetal intra-abdominal cysts seen on antenatal sonography pose a diagnostic problem as they may have many etiological origins. We present a case of a hepatic cyst measuring 11 x 7 x 7 mm that was diagnosed at 13 weeks' gestation by transvaginal sonography. The cyst increased in proportion with the growth of the fetus. Ultrasound-guided needle aspiration of the cyst at 22 weeks' gestation helped to clearly identify the formerly displaced gall bladder and demonstrated the intrahepatic location of the cyst. The aspirated fluid was identified as bile. After aspiration the fluid reaccumulated rapidly. Shortly prior to delivery the cyst measured 75 x 44 x 46 mm. At 39 weeks of gestation a female infant was delivered by forceps (3610 g; Apgar 9/10/10 at 1, 5 and 10 min, respectively). Increasing cyst size and concomitant feeding problems prompted surgery on the 14th day postpartum. A large hepatic cyst was partially excised and marsupialized, confirming the prenatal diagnosis. The postoperative course was complicated by cholangitis, septicemia and recurrence of the cyst. Therefore Roux-en-Y hepatojejunostomy was performed in the second month of life. The postoperative period was uneventful and the child was doing well at the time of writing.

Our findings suggest that fluorescence diagnosis using 5-aminolevulinic acid is feasible and can improve the diagnosis of endometriosis in nonpigmented and occult endometrial lesions. Fluorescence diagnosis is a promising new tool in the diagnosis of endometriosis.

A twin-to-twin transfusion syndrome was diagnosed in a monochorionic-diamniotic pregnancy at 18 weeks' gestation without any malformation, especially heart defect. In spite of the aggressive treatment (serial amnioreduction, digoxin treatment) the donor twin died at 25 weeks and twin reversed arterial perfusion (TRAP) sequence developed and was documented by Doppler ultrasound. In the TRAP-twin, the route of the reversed blood flow from the umbilical arteries was as follows: descending aorta, aortic arch, ascending aorta, aortic valve, left ventricle, mitral valve, left atrium, foramen ovale, right atrium, inferior vena cava, ductus venosus; and back to the placenta through the umbilical vein. After a 12-h observation period the twin reversed arterial perfusion sequence disappeared. During this period ultrasound and fetal blood sampling revealed no sign of fetal anemia or disseminated intravascular coagulation in the surviving twin. Based on our observations, we propose, that the death of one of the twins in monochorionic pregnancy can result in twin reversed arterial perfusion sequence, which is an ultimately rare phenomenon in the second trimester. To our knowledge, this is the first reported case of twin reversed arterial perfusion sequence subsequent to the intrauterine demise of one twin in twin-to-twin transfusion syndrome in which the TRAP-twin had no cardiac malformation.

Aneurysm of the umbilical cord is an extremely rare vascular anomaly. We report a case of umbilical cord aneurysm with arteriovenous fistula in a fetus with trisomy 18. At 34 weeks' gestation a fetus with suspected intrauterine growth restriction and oligohydramnios was referred to our institution. Ultrasound examination was confirmatory and additionally revealed multiple markers for trisomy 18. In the umbilical cord an aneurysm was diagnosed characterized by a cystic lesion with hyperechogenic rim measuring 18 x 18 x 19 mm in diameter. Color flow and spectral Doppler examinations showed a jet originating from one of the umbilical arteries entering the cystic lesion which appeared to be the dilated umbilical vein. Fetal blood sampling and subsequent karyotyping revealed trisomy 18 (47, XY, +18). The patient elected to terminate the pregnancy. Pathologic examination of placenta and umbilical cord confirmed the prenatal diagnosis of umbilical cord aneurysm and arteriovenous fistula. Histology demonstrated a strongly dilated umbilical vein, one moderately dilated artery and a second, apparently normal artery.

We did a retrospective survey of 83 patients who had laparoscopic removal of a benign dermoid cyst in our hospital since 1994. Preoperative transvaginal sonography led to the correct diagnosis in 57 cases (69%). In 59 cases cystectomy with ovarian conservation was performed; spillage of cyst contents occurred in 39 cases (66%). Salpingo-oophorectomy was performed in 24 patients with spillage in 8 cases (24%). The mean tumor size (n=83) was 4.5+/-1.6 cm and 4.9+/-2.8 cm for unspilled and spilled cysts, respectively. The tumor was placed in an endobag in 62 cases. No intra- or postoperative complications occurred. No case of chemical peritonitis was noted.
