Adult Jejunojejunal Intussusception Caused by Small Bowel Leiomyoma.

This article reports a case of a patient with intestinal obstruction admitted to the hospital whose presumed diagnosis by CT was jejunojejunal intussusception. The patient underwent exploratory laparotomy with an enterectomy of the invaginated segment. The histopathological and immunohistochemical results of the surgical specimen confirmed the presence of a small bowel leiomyoma. This case highlights the importance of a detailed clinical evaluation of patients with an intestinal obstruction who seek emergency care. The cause of intestinal obstruction is a diagnostic challenge due to the numerous pathologies that can lead to the development of the condition. Guided anamnesis, detailed physical examinations, and accurate subsidiary exams that do not delay diagnosis are the cornerstones of emergency room care. Knowing the ideal time to refer the patient to the operating room requires knowledge and practice. The patient reported in this article with jejunal leiomyoma as a cause of intestinal intussusception is surprising for its rarity and illustrates the range of pathologies that can lead to intestinal obstruction.
