Patient's question:
Medical Description: During the ultrasound, two abnormal data were found. There is a 0.8 cm echo-free area in the posterior fossa, and the diameter of the left renal pelvis of the fetus is 0.4 cm. Is this result normal?History of Treatment and Effect: No treatment has been performed.
Help Needed: Please help answer this question. Is it abnormal?
Doctor's answer:
Analysis of the condition: The width of the echo-free area in the posterior fossa is 0.8 cm, which is still within the normal range. The normal value is less than 1.0 cm. Please follow up on this. The diameter of the fetal left renal pelvis is 0.4 cm, which is also not a significant issue. Generally, it is not a problem if it does not exceed 1.0 cm. It is possible that the fetus is slightly holding back urine.Suggestions: Overall, there is an issue, but it is not severe. It is recommended to follow up, as it may resolve on its own with further development.
