This most commonly occurs in boys up to 16 years of age but has been reported in adults. The patient complains of sudden pain around the superior pole of the testicle or epididymis as the appendix undergoes necrosis and inflammation. Early in the course, palpation of a firm, tender nodule in this area will confirm the diagnosis.
