A 23 years old nulligravida presents with a 2-day history of sharp intermittent RLQ abdominal pain, nonradiating, without any alleviating factors, exacerbated with movement, progressively worsening, and not associated with any GI symptoms.

What potential sequelae do you need to be concerned about?
