Knee pain Right: There is mild sharpening of the tibial spines but the knee otherwise appears normal for the patient's age.Left: Moderate to severe osteoarthritis affects the knee with narrowing of the medial tibiofemoral compartment and tricompartmental osteophytes. There is there is a geographic lucent lesion within the fibular head and neck which extends into the proximal diaphysis. There is no cortical destruction or other particularly aggressive features but further evaluation with MRI is recommended.
1. Moderate to severe osteoarthritis of the left knee.2. Radiographic lucent lesion within the proximal fibula which is nonspecific and may represent an intraosseous ganglion but a more aggressive lesion such as a giant cell tumor cannot be excluded on the basis of this imaging exam alone. MRI of the knee with and without contrast is recommended to further evaluate this finding.These findings were communicated to the ordering clinician Dr. M. Cheng via telephone at the time of dictation.
