[2025-10-01T21:19:32.962200] [PI reasoning] **Identifying first trimester abnormalities**

I’m focusing on which abnormalities can be diagnosed during the first trimester. I know anencephaly can be detected by ultrasound around 11-14 weeks due to the absence of the cranial vault. Encephalocele might be more challenging to spot early, though some sources say it can still be diagnosed in the first trimester. Meningocele and microcephaly are usually diagnosed later. Overall, it seems like anencephaly is the best answer, but I’ll search to confirm.
