Greetings In hydrocephalus there is pathological increase in the size of the cerebral ventricles. Prevalence: Hydrocephalus is found in about 2 per 1,000 births. Ventriculomegaly (lateral ventricle diameter of 10 mm or more) is found in 1% of pregnancies at the 20-23 week scan. Therefore the majority of fetuses with ventriculomegaly do not develop hydrocephalus. Etiology: This may result from chromosomal and genetic abnormalities, intrauterine hemorrhage or congenital infection, although many cases have as yet no clear-cut etiology. Diagnosis: Fetal hydrocephalus is diagnosed sonographically, by the demonstration of abnormally dilated lateral cerebral ventricles. Certainly before 24 weeks and particularly in cases of associated spina bifida, the head circumference may be small rather than large for gestation. A transverse scan of the fetal head at the level of the cavum septum pellucidum will demonstrate the dilated lateral ventricles, defined by a diameter of 10 mm or more. The choroid plexuses, which normally fill the lateral ventricles, are surrounded by fluid. A distinction is usually made between mild, or borderline, ventriculomegaly (diameter of the posterior horn 10-15 mm) and overt ventriculomegaly or hydrocephalus (diameter greater than 15 mm). Patho-physiology of Hydrocephalus: If the molecular motion of Calc.phos is disturbed within the epithelial cells of serous membranes, a sero-albuminous exudation within the sacs takes place. Thus, effusion develops as in hydrops genu,hygroma patellae, hydrocephaloid conditions, acute or chronic. Minute doses of Calc.phos will absorb these exudations. Calcarea Phos given during pregnancy will prevent mothers from giving birth to hydrocephalic babies. ( Para 39, Hints from Masters, P.R. Rao ) Calc-F or Calc-P in the 6th and 7th month of gestation according to Dr.M.Tyler Ultrasonic pictures of Hydrocephalus http://lewfh.tripod.com/holisticmultimediasetup/ With regards
