57 year old female with right gluteal nodules and history of stem cell transplant. Note is made of a lobulated collection within the subcutaneous tissues along the posterior aspect of the right gluteus maximus measuring approximately 3.8 x 2.5 cm. An additional collection is identified within the subcutaneous tissues along the posterior aspect of the right hemipelvis just lateral to the gluteal crease, measuring 1.9 x 1.7 cm. Additionally, there is a smaller subcentimeter collection identified along the right gluteal crease with an apparent sinus tract extending to the level of the skin surface (image 38; series 4). There is diffuse nonspecific subcutaneous edema about the pelvis most pronounced along the lateral aspect of the hips. Heterogeneous bone marrow signal abnormality is nonspecific but can be seen in patients with anemia or myeloproliferative disorders. The imaged musculature of the pelvis is within normal limits. There are multiple prominent inguinal lymph nodes identified bilaterally. There is a small amount of free fluid within the pelvis. Evaluation of the pelvic viscera is limited on this noncontrast examination.
Diffuse nonspecific subcutaneous edema as described above. Multiple lobulated collections within the subcutaneous tissue along the posterior aspect of the right hemipelvis as described above. Superimposed infection/abscess formation cannot be excluded on this noncontrast examination. Other findings as described above.
