MRI - MRI - Targeted study
The low-grade chondral lesion, abuts, mildly scallops the anterior and medial cortex of the distal tibial diaphysis, is unchanged in size. There is no extraosseous extension or periosteal reaction. Enhancement pattern is consistent with a low-grade lesion with no dedifferentiation detected. There is faint fascial thickening over extensor digitorum longus at the level of the tumour consistent with the biopsy path scarring, with no nodularity of this area seen. This lesion measures 12 mm in cross-section and 16 mm in length. No skip lesions are seen the rest of the tibia or the adjacent fibula. Longitudinal split tear of the peroneus brevis is noted.
