ROQUE-RAMOS, Lídia et al. Pelvic inflammatory myofibroblastic tumor mimicking a rectal cancer. Rev. esp. enferm. dig. [online]. 2016, vol.108, n.1, pp.43-47. ISSN 1130-0108.

We report a case of a 50-year-old woman who presented to the emergency department with large bowel obstruction and anemia. The initial imaging study suggested an inoperable rectal tumor with involvement of surrounding structures. In this paper, we discuss the diagnostic work-up of this patient with a diagnosis of pelvic/perirectal inflammatory myofibroblastic tumor (IMT). IMT is a rare tumor with intermediate malignant potential that frequently mimics clinical and imaging features of malignancy. Additionally, to the best of our knowledge, this is the first case of a pelvic IMT that regressed without surgical excision.

Palabras clave : Inflammatory myofibroblastic tumor; Rectal cancer; Endoscopic ultrasound; Magnetic resonance imaging.
