Chiari-like malformation (CM) the most common cause of foramen magnum obstruction and syringomyelia in dogs. Syringomyelia (SM) is a disease of the spinal cord typified by fluid filled cavities, or syrinxes, within the spinal cord substance but it can cause pain by disrupting the cerebrospinal fluid (CSF), in the brain [1] CM is a condition characterized by the mismatch of size between the ...
The term diffuse is used if more than 30% of distal villi are involved. [citation needed] VUE has 2 prominent distinct patterns. Approximately 50% of the cases only involve the distal villi (mature intermediate and terminal villi) and do not involve the proximal stem villi, the anchoring villi embedded in the basal plate, and the chorionic plate.
The chorionic villi are at first small and non-vascular. 13–15 days: trophoblast only [1] Secondary: The villi increase in size and ramify, while the mesoderm grows into them. 16–21 days: trophoblast and mesoderm [1] Tertiary: Branches of the umbilical artery and umbilical vein grow into the mesoderm, and in this way the chorionic villi are ...

Placenta with attached fetal membranes (ruptured at the margin at the left in the image), which consists of the chorion (outer layer) and amnion (inner layer).. The part of the chorion that is in contact with the decidua capsularis undergoes atrophy, so that by the fourth month scarcely a trace of the villi is left.
Symptoms in dogs include acute arthritis, anorexia and lethargy. There is no rash as is typically seen in humans. [11] Ehrlichiosis is a disease caused by Ehrlichia canis and spread by the brown dog tick, Rhipicephalus sanguineus. Signs include fever, vasculitis, and low blood counts. [6]
Since choriocarcinomas include syncytiotrophoblasts (beta-HCG producing cells), they cause elevated blood levels of beta-human chorionic gonadotropin. Syncytiotrophoblasts are large multi-nucleated cells with eosinophilic cytoplasm. They often surround the cytotrophoblasts, reminiscent of their normal anatomical relationship in chorionic villi ...
