Extragastrointestinal stromal tumor of the mesoappendix: CT findings and a review of the literature

Abstract

Background

Gastrointestinal stromal tumors (GISTs) are nonepithelial, mesenchymal neoplasms that rarely occur in children.

Case presentation

We present a unique case of a GIST that developed outside the gastrointestinal tract within the mesoappendix of a 6-year old boy. Computed tomography (CT) revealed a slightly lobulated, homogeneous soft-tissue mass, with marked contrast enhancement.

Conclusion

This case study provides new insight into the CT appearance of extragastrointestinal stromal tumors.
