Reason: evaluate for lytic lesions History: pain Again seen is a lobulated subcentimeter focus of intermediate signal intensity on T1-weighted images which is hyperintense on T2-weighted images within the intertrochanteric region of the left femur. There is enhancement following gadolinium administration. This measures 6 mm in the transverse dimension and approximately 7 mm in the craniocaudal dimension. These dimensions are identical to those seen on the prior examination. The reference L5 vertebral body lesion also appears unchanged. The hip joints and sacroiliac joints appear normal. The pubic symphysis appears normal. The imaged musculature of the pelvis is unremarkable.
1. Small focus of signal abnormality in the left intertrochanteric region appears similar to the prior study. While its is possible that this may represent the residua of a treated metastases, this could represent a benign cartilaginous rest.2. Treated L5 metastatic lesion, appearing similar to the prior study. No new findings.
