Lesions
involving the outer surface of the bone in children: a pictorial review. Cortical desmoid at the postero-medial aspect of the left femoral metaphysis in a 10-year-old girl. Sagittal a and axial b CT images show a scalloped radiolucent lesion with a thin sclerotic rim (arrow) along the posteromedial distal femoral metaphysis. Coronal T1 c and axial T2 fat-suppressed d images demonstrate low signal on T1 and high signal on T2 (white arrows on c and black arrows on d)
