Male 67 years old Reason: evaluate sclerotic foci seen on Xray, concern for metastatic disease. History: HCC, prostate cancer, new worsening of R hip pain. BONE MARROW: Hardware components of a total right hip arthroplasty device cause degradation of image quality and limit evaluation in particular of the right hip and right hemipelvis. Two well-circumscribed T1 hypointense/stir hypointense signal lesions are identified, one within the superior aspect of the L5 vertebral body and a second within the right superior pubic ramus. The L5 lesion measures 2.1 x 1.8 cm (series 5, image 33), remeasured on prior study at 2.0 x 2.0 cm, and the right superior pubic ramus lesion measures 1.0 x 0.9 cm (series 5, image 13), remeasured on prior study at 1.2 x 0.9 cm. Both lesions are stable in size allowing for differences in imaging technique. The overlying cortex is intact and there is no surrounding bone marrow edema. There are no new lesions identified.SOFT TISSUES: No significant abnormality noted. JOINTS: No significant abnormality noted.ADDITIONAL
1. Two indeterminate bone lesions are stable compared to prior studies dating back to 03/11/14. Given the interval stability, the absence of new lesions and the findings on prior nuclear medicine bone study, favor benign etiology however given the patient's history of prostate cancer, ongoing surveillance is recommended.
