80-year-old female with a history of neurofibromatosis type I status post excision of right buttock lesion. Postsurgical changes of a resection of a malignant peripheral nerve sheath tumor in the right buttock. No residual lesion or abnormal enhancement is identified. The enhancing mass within the subcutaneous fat of the posterior left buttock has not significantly changed and measures approximately 3 cm in diameter. Accounting for differences in technique, positioning, and inter-user measurement the enhancing mass within the musculature anterior to the proximal left femur has not substantially changed. Multiple scattered cutaneous and intramuscular neurofibromas are noted bilaterally. Additional findings have not substantially changed.Hypointense mass within the uterus likely represents a fibroid. Heterogeneous appearance of the bone marrow likely reflects residual or retroverted red marrow. Osteoarthritic changes have not significantly changed. Degenerative disc disease affects the lumbar spine most severe at L5-S1.
1. Postsurgical changes of a resection of a malignant peripheral nerve sheath tumor in the right buttock without findings to suggest locoregional recurrence.2. No significant change in additional findings including multiple scattered cutaneous and intramuscular neurofibromas.
