28 Possible Causes for Sclerosis of Distal Femur

  • Chondroma

    Three lesions were located in the proximal humerus, with one each in the distal radius, distal femur, proximal tibia and scapula.[ncbi.nlm.nih.gov] Radiographic and CT features deemed highly suggestive of juxtacortical chondroma included cortical scalloping, underlying cortical sclerosis and overhanging margins.[ncbi.nlm.nih.gov]

  • Bone Necrosis

    The distal femur and the proximal tibia are the sites most commonly involved.[emedicine.medscape.com] […] chronic or inactive forms of pancreatitis (see the image below). [22] Epiphyseal involvement is characterized by lucencies of mottled appearance or lucencies interspersed with sclerosis[emedicine.medscape.com]

  • Avascular Necrosis

    The distal femur and the proximal tibia are the sites most commonly involved.[emedicine.medscape.com] […] chronic or inactive forms of pancreatitis (see the image below). [22] Epiphyseal involvement is characterized by lucencies of mottled appearance or lucencies interspersed with sclerosis[emedicine.medscape.com]

  • Osteosarcoma

    Frontal radiograph of the distal femur in a patient with telangiectatic osteosarcoma.[emedicine.com] The radiograph shows mixed medullary sclerosis and lucency, cortical destruction medially, aggressive periosteal changes, and a large soft-tissue mass with peripheral ossification[emedicine.com]

  • Chondroblastoma

    Radiographs of the left knee showed a radiolucent lesion with marginal sclerosis in the distal epiphysis of the left femur (Figure 1 a,b).[jmedicalcasereports.biomedcentral.com] Figure 1 Lesion in the distal epiphysis of the left femur showed marginal sclerosis on radiographs (a,b:arrowheads) and bone edema in magnetic resonance T1-weighted Gd-enhanced[jmedicalcasereports.biomedcentral.com]

  • Brodie Abscess

    Distal tibia, proximal tibia, distal femur, proximal or distal fibula, and distal radius.[en.wikipedia.org] Oval, elliptical, or serpentine radiolucency usually greater than 1 cm surrounded by a heavily reactive sclerosis, granulation tissue, and a nidus often less than 1 cm.[en.wikipedia.org]

  • Chronic Recurrent Multifocal Osteomyelitis

    A radiograph of the right knee showed periosteal reaction of the medial aspect of the distal femur and focal lucencies and sclerosis in the metaphysis ( A ).[consultant360.com]

  • Hereditary Hyperphosphatasia

    Dense cortical sclerosis involves the proximal femur and the lower portion of the ilium. 10. • Fig B 5-8 Fluorosis.[slideshare.net] Characteristic is the combination of avascular necrosis of the femoral head and an “Erlenmeyer flask” deformity at the distal femur.[musculoskeletalkey.com] The distal phalanges are hypoplastic, and the terminal tufts are absent. 9. Fig B 5-7 Melorheostosis.[slideshare.net]

  • Schwartz-Lelek Syndrome

    The distal femur was notable for a narrow diaphysis and widened metaphysis, resulting in an "Erlenmeyer flask"-shaped appearance ( Fig. 3 ).[e-aps.org] Sclerosis is the main feature in the skull. Long bones have widened metaphyses, appearing club-shaped, particularly at the distal femur.[merckmanuals.com] femur Hyperostosis Unilateral facial palsy Abnormality of the nasopharynx Nasal obstruction Atresia of the external auditory canal Sclerosis of skull base Telecanthus Wide[mendelian.co]

  • Rickets

    (b) T1-weighted MR images show abnormal metaphyseal signal intensity in the distal femur and proximal tibia (arrowheads). Figure 9a.[doi.org] Anteroposterior (a) and lateral (b) radiographs demonstrate bowing with focal sclerosis and a notched medial cortex in the distal third of the tibia. Figure 9b.[doi.org]
