Which finding is most specific for chylous ascites?

• A. Milky appearance with high triglycerides.
• B. Clear yellow ascites with low protein.
• C. Bloody ascites.
• D. Purulent ascites.

Answer: (A)

Chylous ascites is identified by lipid-rich lymph leaking into the peritoneal cavity, which makes the fluid look milky and contain high triglycerides. When ascitic fluid is milky and its triglyceride content is above about 200 mg/dL (often with chylomicrons present), this combination is highly specific for chyle leakage into the abdomen. Other types of ascites have different appearances and compositions: a clear yellow fluid with low protein suggests a transudate from things like portal hypertension, bloody ascites points to bleeding or malignancy, and purulent ascites indicates infection. So the milky appearance paired with high triglycerides directly reflects chyle in the abdomen, making it the most specific finding for chylous ascites.
