RESUMEN
We present a case of a female patient with right lower quadrant abdominal pain, in whom transvaginal ultrasound facilitated the diagnosis of acute appendicitis. The insertion of the appendix into the cecum was demonstrated with direct continuity between the cecal lumen and the appendix. The inflamed appendix was in close proximity to the right ovary and was distinguished by a thick edematous wall and fluid in the lumen. This combination of findings may comprise a new sonographic sign for the diagnosis of acute appendicitis, particularly when performed by transvaginal sonography.

A case report of sacrococcygeal teratoma prenatally diagnosed at 23 weeks of amenorrhea, subsequently causing dilatation of both lower and upper urinary tracts is presented. The importance of repeated ultrasonographic evaluation of fetuses with sacrococcygeal teratoma is discussed.

A large number of hydronephrotic kidneys (108) were diagnosed prenatally in 69 infants between 1987 and 1991 and subsequently confirmed postnatally. Prenatal morphometric measurements were done in order to find reliable parameters for the detection of a group at risk for surgical treatment. A second aim of the study was to describe the natural history and management of hydronephrosis detected prenatally. We devised a classification of postnatal obstructive uropathy using ultrasonography and the renal scan. Accordingly, we classified the patients as having mild, moderate or severe hydronephrosis. A renal pelvic antero-posterior diameter (APD) of 9 mm or more, and a pelvic-to-renal APD ratio of 0.45 before 32 weeks of gestation and 0.52 thereafter, were found to be useful for the detection of severe outcome. Our new parameter, a pelvic-to-renal volume ratio of greater than 0.08, can also be used for this purpose.

Chorionic villus sampling (CVS) was performed in 12 pregnant women (9-25 gestational weeks) with ultrasonographic evidence of missed abortion. An ultrasonographically guided transabdominal (eight cases) or transcervical (four cases) approach was used. Fetal karyotyping was successful in all cases; in five, chromosomal aberrations were found and in seven, chromosome analyses revealed normal karyotypes. Tissue culture for fetal karyotyping was successful in only 72.5 per cent of 40 live pregnancies which were electively interrupted because of abnormal ultrasonographic findings or an abnormal fetal karyotype, and in 57 per cent of seven missed abortions. CVS is suggested as a feasible and effective method for fetal karyotyping in missed abortions and it seems to be superior to post-abortion tissue culture.
