Pelvic Desmoid Tumor: A Rare Case with Difficult Diagnosis and Treatment

Figure 1

Pelvic magnetic resonance imaging showing the following: (a) sagittal T2-weighted spin-echo image: a round mass with very low homogeneous signal intensity in its central part is present; (b) sagittal 90 second postgadolinium T1-weighted fat-suppressed spin-echo image: the upper aspect of the mass enhances reflecting active disease and the nodular desmoid tumor exhibits minimal enhancement confirming its fibrous nature; (c) paracoronal T2-weighted; and (d) postgadolinium T1-weighted images showing right kidney hydronephrosis due to an extraureteral obstruction confirmed to be a desmoid tumor.
