PARIETAL VS INTRA- ABDOMINAL
-Can be ascertain by either head rising or leg rising test.

When you lift your head and shoulders,if the swelling disappears or become less prominent,then the swelling inside the abdomen (Intra abdominal).

If the swelling becomes more prominent or remain the same then it's parietal.

For lower abdominal swelling,lying on bed and lifting both the legs bring the same interpretation as head rising test.


INTRA-PERITONEAL OR RETROPERITONEAL

Do a knee elbow position .
If the lump disappears or become less prominent,then its retroperitoneal.If swelling becomes more prominent or remains the same, it's intra-peritoneal.
