48-year-old male with DLBCL of the primary bone site (left hip). Restaging examination. Please reassess for response in the primary site BONE MARROW: Note is made of increased signal abnormality within the left acetabulum extending inferiorly along the left inferior ramus, consistent with the patient's history of primary lymphoma of bone. There is associated enhancement on postcontrast sequences. There is cortical destruction with a small amount of soft tissue extension involving the obturator internus muscle on the left. When compared to prior imaging from 8/24/2015, these findings appear decreased in size and extent. There is also nonspecific increased signal abnormality on fluid sensitive sequences within the superolateral left femoral head/neck which does not definitively enhance, but also appears decreased in size when compared to the prior study. Attention to this finding on follow-up examination is recommended.SOFT TISSUES: Again seen is enhancing soft tissue extension involving the left obturator internus muscle which appears decreased in size when compared to the prior examination.JOINTS: The femoroacetabular joint alignment is anatomic.ADDITIONAL
Enhancing lesion within the left acetabulum extending to the inferior pubic ramus with soft tissue extension as described above, consistent with the patient's known history of primary lymphoma of bone. These findings appear decreased in size and extent when compared to the prior examination from 8/24/2015. Other findings as described above.
