1/35. An unusual case of the complete Currarino triad: case report, discussion of the literature and the embryogenic implications.OBJECTIVE AND IMPORTANCE: We present and illustrate an unusual case of the complete familial Currarino triad (an association between a bony sacral defect, a presacral mass, and an anorectal malformation) in which the teratoma arose from the conus medullaris and contained mature neurons, glia, and branching ependymal canals that were in communication with a terminal syrinx. The embryogenic implications are discussed. CLINICAL PRESENTATION: The patient was a term neonate when discovered to have imperforate anus. Further workup revealed lumbosacral dysraphism with a presacral mass, a rectovaginal fistula, and a single pelvic kidney. The family pedigree revealed a familial transmission pattern; the patient had a second cousin with anal atresia and a first cousin with similar sacral anomalies. The motor level was L4 with trace L5, and there was absent sensation in the sacral dermatomes. INTERVENTION: A diverting colostomy was performed on Day 14, and the infant returned at 3 months of age to undergo near-total resection through the previous abdominal approach. Only a subtotal resection was possible because the mass arose from the low-lying conus and was firmly adherent to the sacral nerve roots and iliac vessel. Follow-up magnetic resonance imaging performed 18 months after surgery revealed that the residual tumor had not progressed. CONCLUSION: Complete Currarino triad is rare and is familial in half of the cases. The special features of the tumor in our case were the presence of mature neurons with ependymal canals and its origin from the conus. The possible embryogenesis may provide evidence that the caudal notochord is important for organized secondary neurulation.- - - - - - - - - - ranking = 1keywords = single (Clic here for more details about this article) |
2/35. A novel syndrome involving primary skeletal growth and retardation in siblings.An identical pattern of malformations was found in two brothers both having microcephaly and severe developmental delay. Additionally, they had hypotelorism, epicanthic folds, and convergent strabismus. There was shortening of either the radius or the tibia and shortening of the first metacarpals. Persistently dorsally flexed fingers and toes were noted, all of which are unusually long. Both boys had a high-pitched voice and were unable to communicate verbally at the age of 4.5 years. They both developed short stature. One brother has anal atresia; the other had a pulmonary artery atresia, VSD, ASD, and an over-riding aorta. This apparently new syndrome is possibly an autosomal, or a X-linked recessive trait.- - - - - - - - - - ranking = 0.4163875922267keywords = artery (Clic here for more details about this article) |
3/35. prenatal diagnosis of facial clefting as part of the oculo-auriculo-vertebral spectrum.We report a rare facial cleft (type 2 according to the Tessier classification) as the first presenting echographic sign of the oculo-auriculo-vertebral spectrum (OAVS) (goldenhar syndrome). Associated malformations included a left lateral cleft with macrostomia, left ear hypoplasia, left preauricular tag, single umbilical artery, hyposegmentation of the left lung and imperforatio ani.- - - - - - - - - - ranking = 47896.857775775keywords = single umbilical artery, single umbilical, umbilical artery, umbilical, single, artery (Clic here for more details about this article) |
4/35. When is meconium-stained cord actually bile-stained cord? Case report and literature review.It is reasonable to assume that an umbilical cord stained green is due to the baby having passed meconium in utero. We describe a newborn baby in whom there was a delay in diagnosing an imperforate anus because the baby's umbilical cord was stained green with bile and it was assumed that the baby had passed meconium in utero.- - - - - - - - - - ranking = 56.937915589447keywords = umbilical (Clic here for more details about this article) |
5/35. Sacrococcygeal teratoma with anorectal malformation.A 7-month-old child presented with imperforate anus, penoscrotal hypospadias and transposition, and a midline mucosa-lined perineal mass. At surgery the mass was found to be supplied by the median sacral artery. It was excised and the anorectal malformation was repaired by posterior sagittal anorectoplasty. Histologically the mass revealed well-differentiated colonic tissue. The final diagnosis was well-differentiated sacrococcygeal teratoma in association with anorectal malformation.- - - - - - - - - - ranking = 0.4163875922267keywords = artery (Clic here for more details about this article) |
6/35. Cloacal exstrophy: prenatal diagnosis before rupture of the cloacal membrane.Embryologically, cloacal exstrophy is thought to result from persistence and subsequent rupture of the infraumbilical cloacal membrane during the fifth embryonic week. We report a case of cloacal exstrophy in which a prenatal diagnosis was made prior to rupture of the cloacal membrane. A routine ultrasound at 17 weeks' gestation demonstrated monoamniotic twins. One twin was normal, but the other was found to have a sacral myelomeningocele, "rocker-bottom" feet, splaying of the pubic rami, and a large cystic mass protruding from the infraumbilical anterior abdominal wall. A repeat ultrasound was performed at 22 weeks, with the same findings. At 26 weeks, further examination showed disappearance of the abdominal cyst, a small omphalocele, no demonstrable bladder, and the suggestion of prolapsed bowel inferior to the umbilical cord insertion. After delivery at 34 weeks, the abnormal twin was found to have the typical findings of cloacal exstrophy, myelomeningocele, bilateral lower limb anomalies, and extremely foreshortened small bowel. rupture of the presumed cloacal membrane after 22 weeks in this case is inconsistent with our current understanding of the embryology of this anomaly, and should stimulate a reexamination of the current concepts. If the characteristic features are recognized, cloacal exstrophy can be diagnosed by prenatal ultrasound, permitting prenatal counseling and appropriate perinatal management.- - - - - - - - - - ranking = 85.40687338417keywords = umbilical (Clic here for more details about this article) |
7/35. Cloacal exstrophy in an infant with 9q34.1-qter deletion resulting from a de novo unbalanced translocation between chromosome 9q and Yq.Cloacal exstrophy is a rare malformation, belonging to a spectrum of birth defects, which, in order of severity, includes phallic separation with epispadias, pubic diastasis, bladder exstrophy, and cloacal exstrophy. This malformation overlaps the OEIS complex (O = omphalocele, E = bladder exstrophy, I = imperforate anus, S = spinal defects). The etiology of cloacal exstrophy is unknown to date. It may result from either a single defect of early blastogenesis or a defect of mesodermal migration during the primitive streak period. We report an infant with cloacal exstrophy, exomphalos, right kidney agenesis, ambiguous external genitalia, and axial hypotonia. The karyotype showed a de novo unbalanced translocation between the long arm of chromosome 9 and the long arm of chromosome Y resulting in a 9q34.1-qter deletion. Reviewing the literature, we did not find any observation of cloacal exstrophy associated with a structural chromosomal abnormality. The steroidogenic factor 1 (SF1) gene, included in the deleted region, was a good candidate gene but no pathogenic mutation was found by direct sequencing. We hypothesize that another gene, expressed early in embryogenesis and responsible for cloacal exstrophy, is present in the 9q34.1-qter region.- - - - - - - - - - ranking = 1keywords = single (Clic here for more details about this article) |
8/35. Urogenital sinus, rectovaginal fistula, and an anterior stenosed anus--another cloacal variant.The persistent cloaca is one of the most complex and challenging developmental malformations. It is a rare anomaly occurring only in the female newborn and is represented by the association of urogenital sinus with an anorectal malformation (arm). Each case is probably unique. We report here one such case of cloaca with the VATER association-tracheoesophageal fistula (TOF) with a urogenital sinus, rectovaginal fistula, and an anteposed stenosed anus, along with preaxial syndactyly of the right hand. The spine, renal, and cardiac systems were normal. Interim management was directed towards repair of the TOF and a right transverse defunctioning colostomy. Despite thorough radioendoscopic preoperative investigations, the complexity of the cloacal anomaly was not delineated until surgery. This case is a rather rare combination of an intermediate form of the cloacal-arm spectrum. Such patients present with many diagnostic and therapeutic problems. Interval surgery should be directed towards decompression of the affected organ systems, and definitive surgery must be carefully planned and, whenever possible, done in a single stage with simultaneous multisystem repair to correct all significant malformations related to the cloacal complex.- - - - - - - - - - ranking = 1keywords = single (Clic here for more details about this article) |
9/35. Using color Doppler sonography to identify the perivesical umbilical arteries: a useful method in the prenatal diagnosis of omphalocele-exstrophy-imperforate anus-spinal defects complex.OBJECTIVE: To describe the different prenatal sonographic findings in 3 cases of omphalocele-exstrophy-imperforate anus-spinal defects (OEIS) complex, or cloacal exstrophy. methods: Three patients with OEIS complex were examined by sonography. In 2 (cases 2 and 3) of the 3 cases, color Doppler sonography was applied to the area of cord insertion and the abdominal mass to determine the origin of the abdominal mass. RESULTS: Three cases of OEIS complex with different sonographic appearances are included in this series. An absent bladder without an abdominal mass but with bowel floating in the amniotic cavity was revealed in case 1; an absent bladder with a lower anterior abdominal mass was found in the second trimester in case 2; and a large cystlike mass located in the anterior abdominal wall was found in case 3. color Doppler imaging showed that the abdominal mass originated from the urinary bladder in cases 2 and 3; therefore, OEIS complex was presumptively diagnosed antenatally in these cases. In all cases, OEIS complex was confirmed postnatally. CONCLUSIONS: Omphalocele-exstrophy-imperforate anus-spinal defects complex should be considered in patients with an absent bladder combined with either an anterior abdominal wall mass or defects. Special attention should be given to search for other combined anomalies. We suggest that color Doppler sonography for identifying the perivesical umbilical arteries is a very useful method in establishing of the diagnosis of OEIS complex.- - - - - - - - - - ranking = 142.34478897362keywords = umbilical (Clic here for more details about this article) |
10/35. Renovascular hypertension complicated with VATER association.We report herein a case of a girl with renovascular hypertension associated with VATER association. Her plasma renin activity and aldosterone were high. The ultrasonic echogram and renogram revealed a right hypoplastic kidney without function and a normal-sized left kidney with normal function. Renal angiography revealed a small diameter right main renal artery and a normal left main renal artery with segmental stenosis of left branching renal arteries in the middle segment. Selective renal vein sampling indicated that renin secretion was primarily from the left kidney. This is the first report of renovascular hypertension complicated with VATER association.- - - - - - - - - - ranking = 0.8327751844534keywords = artery (Clic here for more details about this article) |
