Metaphyseal fibrous defect (MFD) of the distal femur. (a, b) Anteroposterior and lateral X-ray showing a large radiolucent lesion, with well-defined sclerotic border. (c) Axial CT scan showing the defect with posterior disruption of the cortex

(a, b) Anteroposterior and lateral X-ray showing radiolucent, eccentrically lesion in the distal metaphysis of the femur, juxtaposed to the endosteal surface of one cortex

(a, b) MFD. Roentgenographic anteroposterior and oblique view. Lytic, eccentric elongated lesion in the distal femur; the long axis of the lesion is parallel to the host bone

Fig. 51.4
(a, b) MFD in the posterior aspect of the femur. Anteroposterior and lateral radiographs showing a large lesion with the characteristic pattern
