Right hip pain, metastatic breast cancer 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 and these dimensions are identical to those seen on the prior examination. The reference L5 vertebral body lesion also appears unchanged and there are no additional or new marrow abnormalities identified.The hip joints and sacroiliac joints appear normal with no abnormal enhancement to suggest synovitis. The imaged musculature and tendons of the pelvis are unremarkable.
Signal abnormalities within the left proximal femur and L5 vertebral body are unchanged from the prior exam. There are no new marrow signal abnormalities or other specific findings to account for the patient's hip pain.
