Pain Severe osteoarthritis affects the right hip with bone-on-bone apposition superiorly, appearing similar to that seen on the March 31, 2016 study. Moderate osteoarthritis affects the left hip, also appearing similar to that seen on the March 2016 study. Overall, the bones appear slightly demineralized suggesting osteopenia. There is a 2 cm ovoid lucent focus in the proximal left femoral diaphysis seen on the AP view of the left hip. This may simply represent a benign focus of cortical thinning; however if the patient has a known history of primary malignancy or pain referable to this site, then MRI or skeletal scintigraphy may be considered for further evaluation to exclude metastatic disease. Sclerosis along the left sacroiliac joint is likely degenerative in etiology. Degenerative arthritic changes also affect the visualized lower lumbar spine.
Bilateral hip osteoarthritis, right greater than left. A lucency in the proximal left femur may simply represent a benign focus of cortical thinning; however, if the patient has a known history of primary malignancy or pain referable to this site, then MRI or skeletal scintigraphy may be considered for further evaluation to exclude metastatic disease.
