- Placental morphological variation
- Morphological variation of the placenta
There can be several variations in placental morphology. These include:
- single lobed discoid placenta (single disc): most common scenario
- bilobed placenta: two near equal size lobes
- succenturiate lobe(s): one or more smaller accessory lobes
- circumvallate placenta: rolled placental edges with smaller chorionic plate
- circummarginate placenta
- placenta membranacea
- placenta fenestrata
-
zonary placenta / annular placenta / ring shaped placenta (extreme rare 4)
- horse shoe shaped placenta (where there is no complete ring)
