rovsing sign
murphy’s sign
chandelier’s sign
what does cullen’s sign indicates?
- periumbilical hematoma
- retroperitoneal hemorrhage:
-> hemorrhagic pancreatitis
-> ruptured AAA)

due to diaphragm irritation phrenic nerve signals at left shoulder
what does iliopsoas, obturator, rovsing signs indicate?
- iliopsoas: right hip hyperflexion -> pain
- obturator: internal rotation of the flexed hip -> pain
- rovsing: RLQ pain when palpating LLQ
all indicating appendicitis
what does murphy’s sign indicate?
abbrupt interruption of inspiration on RUQ palpation
acute cholecystitis
what does chandelier’s sign mean?
cervix manipulation induces pain
-PID
