Internal hernias are an infrequent cause of intestinal obstruction with an incidence of 0.2-0.9%, therefore their early diagnosis represents a challenge. The most frequently herniated organ is the small bowel, which results in a wide spectrum of symptoms, varying from mild abdominal pain to acute abdomen. We present the case of an eight-year old patient with nonspecific digestive symptoms, a transoperative diagnosis was made in which an internal hernia was found strangulated by plastron in the distal third of the appendix. Appendectomy was performed and four days later the patient was discharged without complications.
