• Common during the first year of life as well as during puberty
• Presents with nausea/vomiting, abdominal pain, and/or testicular pain
• ALWAYS examine a child for signs of torsion who presents with abdominal pain (especially lower abdominal pain)
• Look for tenderness, firmness, high riding testicle or testicle with unequal lie, swelling, and the absence of a cremasteric reflex
• Consult Urology IMMEDIATELY if you have high suspicion, otherwise proceed to ultrasound
