Large lobulated mass centred on the right gluteus maximus muscle with subaponeurotic downward extension, eliciting a high signal on T1, low signal on T2, STIR and GE with surrounding inflammatory changes of low signal on T1, high signal on T2 and STIR with enhancement on post-contrast sequences.
Numerous bilateral cutaneous and subcutaneous nodules of low signal on T, high signal on T2 and STIR with enhancement suggestive of neurofibromas.
