history of pelvic rhabdomyosarcoma, six months off therapy. Please evaluate for recurrent disease.EXAMINATION: MR pelvis with and without contrast. PELVIS:UTERUS, ADNEXA: Flow-voids seen within the anterior vaginal wall is unchanged. No focal lesion seen in the uterus.BLADDER: No significant abnormality notedLYMPH NODES: No pelvic or inguinal lymphadenopathy.BOWEL, MESENTERY: Focus of fluid signal intensity along the descending colon is favored to represent fluid in the pericolic gutter.BONES, SOFT TISSUES: Interval decrease in high T2 signal intensity within the marrow of the pubic symphysis. Previously seen focus of mild increased T2 marrow signal in the right S2 body is not well seen on current examination. However, there continues to be subtle mottled signal in the pelvic bones. Persistent, yet decreased, T2 signal intensity within the pelvic musculature compared to prior examination. New nonspecific increase T2 signal in the vaginal introitus and the bilateral labia.OTHER: Small amount of free fluid in the pelvis.
1.Improved, yet persistent, subtle mottled bone marrow T2 signal hyperintensity in the pelvic bones and improved increased signal in the pelvic musculature. These findings may be related to prior treatment.2.New nonspecific increase T2 signal in the vaginal introitus and the bilateral labia.
