Multi-lobulated, stair-step lesions. Proximal is to the top and distal is to the bottom of each image. a Medial is to the left and lateral is to the right of the image. b Cranial is to the left and caudal is to the right of the image. a Pig 5, interval 1, left distal femur, frontal plane. There is a multi-lobulated lesion in the metaphyseal-side ossification front, consisting of four triangles close together (arrows) referred to as a stair-step lesion. b Pig 5, interval 1, left distal femur, sagittal plane. The lesion in a also contains three triangles close together in the sagittal plane (arrows)
