With my son, (Down syndrome) they saw an EIF (bright spot on his heart) and because of that, spent many many monthly ultrasounds looking and looking at his heart. The most frequent cause is a small focal germinal matrix hemorrhage with subsequent removal of blood leaving a fluid-filled cyst and surrounding gliosis in the subependymal tissue. Subependymal cysts due to small germinal matrix hemorrhages are a major differential diagnosis. Dilatation of the kidneys (pyelectasis) 4-11 and 4-12) occurs when there is a central abdominal wall defect that results in herniation of intra-abdominal structures into the base of the umbilical cord, which is covered by a membrane.

Reciprocal translocation is a chromosome abnormality caused by exchange of parts between non-homologous chromosomes. Associated abnormalities: Associated with increased risk for trisomy 18 and possibly trisomy 21. Differential diagnosis with respect to origin may be aided by electronmicroscopy and by immunohistochemical staining (28; 36). Subependymal cyst in the trigone region of the lateral ventricle of a 2-month-old infant secondary to a small germinal matrix hemorrhage in the perinatal period. Blake pouch cysts are expansions into the fourth ventricle as an embryonic remnant of ballooning of the superior medullary velum, resulting in an avascular ependymal-lined cyst protruding into the cisterna magna. Ependymal cysts develop as heterotopic ependyma, with the inner layer recognizable as ependyma. Some features, such as pinocytotic vesicles and basement membrane, not usually present in ependyma, suggested a relationship to choroid plexus epithelium. WebTo derive a positive predictive value of isolated choroid plexus cysts for trisomy 18, we reviewed the literature and found a total of 50 fetuses with trisomy 18 who underwent ultrasonographic examination in the midtrimester. Differential diagnosis should also include neurocysticercosis (36). Fernandez C, Soulier M, Coulibaly B, et al.

Finally, ear length at 11-14 wk of gestation has been evaluated in screening for chromosomal defects but the degree of deviation from normal is too small for this measurement to be useful as a marker for trisomy 21 [ 51 ]. /Title The screening test results have to be correlated with normal averages. J Neuropathol Exp Neurol 1992;51(1):58-75. J Med Screen 1995;2(1):18-21. Finally, ear length at 11-14 wk of gestation has been evaluated in screening for chromosomal defects but the degree of deviation from normal is too small for this measurement to be useful as a marker for trisomy 21 [ 51 ]. Choroid plexus cysts (CPC) and echogenic intracardiac focus (EIF) are minor fetal structural changes commonly detected at the second-trimester morphology ultrasound. Most fetuses with these findings will, however, not have chromosomal abnormalities, especially when these findings are isolated. Rarely, a choroid plexus cyst may persist and continue to enlarge postnatally into infancy, acting as a mass effect within its hemisphere and even causing erosion of the ipsilateral calvarium (82).

WebObjective: To determine the infant and early childhood developmental outcome associated with choroid plexus cysts diagnosed prenatally. WebChoroid plexus cysts are commonly found in normal fetuses in the second trimester, but the presence of cysts is an indication for a targeted ultrasound scan for signs associated with J Neurosurg 1993;78(1):101-11. These glands make the WebEchogenic intracardiac focus and choroid plexus cysts are common findings at the midtrimester ultrasound. The primordial choroid plexus grows in a lobulated form; each lobule then forms frond-like expansions followed by villi appearing at the surface as the entire structure becomes more complex with maturation. In the second trimester, the most commonly assessed soft markers include echogenic intracardiac foci, pyelectasis, short femur length, choroid plexus cysts, echogenic bowel, thickened nuchal skin fold, and ventriculomegaly. The importance of the clustering of markers forms the basis of the scoring index, such that individual markers are assigned point values based on their sensitivity and specificity in the detection of Down syndrome. Click to see full answer Keeping this in view, what is a soft marker for Down syndrome? /CreationDate (D:20091013110412-08'00') The most common markers in the second trimester are nuchal thickening, hyperechoic bowel, shortened extremities, renal pyelectasis, echogenic intracardiac foci (EIF) and choroid plexus cysts.
