Talk:jellyfish baby

molar pregnancy
is this the same thing as w:molar pregnancy? if it is, the "babies" have no hearts or brains ... indeed they never get beyond the placenta stage. this paper refers to the w:jellyfish sign, which also involves the placenta, but Im not sure that's the same thing either .... if there's a connection at all, i suspect the term jellyfish babies is a neologism that didnt spread. — Soap — 20:38, 19 April 2023 (UTC)

i found this which suggests that even if it is a rarely used neologism, it has spread to some extent, including into research journals. Attested at least since 1992 according to this report. The latter link suggests that it may indeed be a molar pregnancy, but we can't know. The jellyfish sign now seems to be yet another thing, unrelated to the radiation-linked disorder whether the latter involves molar pregnancy or not. — Soap — 20:52, 19 April 2023 (UTC)

okay, one more post .... Wikipedia says
 * Based on morphology, hydatidiform moles can be divided into two types: in complete moles, all the chorionic villi are vesicular, and no sign of embryonic or fetal development is present. In partial moles some villi are vesicular, whereas others appear more normal, and embryonic/fetal development may be seen but the fetus is always malformed and is never viable.

which suggests that this condition comes in two forms ... a less complete one where some recognizably human tissues do in fact develop, and a complete form in which the placenta never develops distinct tissues, organs, or any kind of visual differentiation except the distinctive grape-like clusters of cells that arise from the cells of the placenta. It seems that a woman is capable of carrying a baby with the less-complete form of the disorder to term, but the baby is in no way viable as its body is still mostly not there. — Soap — 21:07, 19 April 2023 (UTC)
