Proximal Jejunum Leiomyoma unmasked as Acute Volvulus in an adult: a rare case report with management review.

Leiomyoma is one of the rarest mesenchymal tumors which usually arise from different layers of the small bowel. Since small bowel malignancy is a rare condition, these lesions are often detected incidentally. Clinical presentation of this uncommonly observed tumor includes intussusception, volvulus and perforation. However, they usually grow unnoticed until their increasing size starts causing symptoms. Volvulus, commonly seen in infants and children, refers to twisting of an intestinal loop and its mesentery, leading to bowel obstruction. The most common locations for volvulus are the sigmoid colon and caecum. Here we report a case of proximal jejunum volvulus secondary to jejunal leiomyoma in an adult and discuss the varied presentation of jejunal leiomyoma, as well as diagnostic methods and treatment options.
