Adolescent with left upper quadrant pain
Large circumscribed heterogeneous cystic and solid mass centered in the left mesentery. No associated bowel obstruction but difficult to separate the mass from bowel in regions. Large vessels in portions of the mass.
Leiomyomas are composed of fascicles of smooth muscle cells. Leiomyoma most commonly involves the uterus but can occur anywhere there is smooth muscle. A leiomyoma of the mesentery is uncommon; there are case reports in the literature with little dedicated literature to this topic.
Leiomyoma typically demonstrate homogeneous density and intensity at CT and MRI (possibly low T2 signal), similar to smooth muscle, with homogeneous enhancement. Heterogeneity suggests consideration for sarcoma. Alternative considerations include teratoma/germ cell tumor, GIST, desmoid, sarcoma.
