A sessile osteochondroma is noted arising from the medial aspect of distal femoral diaphysis measuring about 7 x 8 mm with overlying cartilage of about 1 mm in thickness. The lesion abuts the vastus medialis muscles.
An isointense T1W and hyperintense T2W area are in the deep soft tissues underneath the vastus medialis muscle, suggestive of adventitious bursitis.
