30-year-old female with abdominal pain and vomiting. Evaluate for plexiform tumor. BONE MARROW: No bone marrow signal abnormality is identified.SOFT TISSUES: There is increased signal abnormality within the right gluteus maximus which is nonspecific but may reflect a combination of postsurgical change and subacute denervation. There is nonspecific subcutaneous edema along the posterior aspect of the right pelvis which may reflect postsurgical change. There is a nonspecific lesion within the right gluteus maximus measuring 12 mm in greatest diameter which demonstrates increased signal abnormality and fluid sensitive sequences. An additional 15 mm lesion is identified within the subcutaneous tissue along the posterior superior aspect of the right gluteal crease. Multiple additional foci of signal abnormality are identified within the right gluteal crease and subcutaneous tissue which are incompletely characterized on this noncontrast examination but likely represent neurofibromas given the patient's history of NF1.JOINTS: There is a small amount of fluid within the joint without evidence of large effusion.ADDITIONAL
Apparent postoperative changes with lesions within the right gluteus maximus muscle and subcutaneous tissue along the posterior aspect of the right hemipelvis are incompletely characterized on this noncontrast examination but likely represent neurofibromas, given the patient's stated history of NF1.
