576 Possible Causes for Radiolucency of the Bones

  • Vitamin D Deficiency

    The bone matrix elsewhere also becomes more radiolucent.[] Later, because the ends of the radius and ulna have become noncalcified and radiolucent, the distance between them and the metacarpal bones appears increased.[] Characteristic deformities result from the bones bending at the cartilage-shaft junction because the shaft is weak.[]

  • Cystitis

    […] indications surgical planning delineate proximal femur defects orientation of deformity views consider all views including 3D reconstructions findings deformity configuration bone[] […] on AP as angle between Hilgenreiner's line and a line through the proximal femoral physis triangular metaphyseal fragment in inferior femoral neck (looks like inverted-Y radiolucency[]

  • Congenital Mandibular Hypoplasia

    […] lesions of bone, mixed radiolucent and radiopaque lesions of bone.[] […] anomalies uses tables and extensive illustrations to depict developmental anomalies, white soft tissue lesions and enlargements, dark soft tissue lesions, ulcerative lesions, radiolucent[]

  • Florid Cemento-Osseous Dysplasia

    Term radiographically this disease shows up like cotton-wool appearance it is patchy radiolucent and radiopaque. bone also has a mosaic bone appearance: involved bone shows[] Radiographs revealed multifocal diffuse bony changes consistent with FCOD and a new radiolucency in the bone of the mandible underlying the swollen and draining soft tissues[] […] borders in maxilla and mandible in irregular pattern Generalized 60-90% bone loss Periapical radiolucency on the remaining mandibular dentition Diagnosis Severe adult chronic[]

  • Exostosis

    The outgrowth has well defined cortical margins without any destruction of the parent bone. [8] The cartilaginous cap is not visualized as it is radiolucent and can be seen[] SE is typically not continuous with the underlying bone, contrary to osteochondroma.[] The cortex and medulla of outgrowth are continuous with the parent bone.[]

  • Ganglion Cyst

    Intraosseous ganglion cyst is a rare bone tumor and the lesion could often be missed.[] Curettage of the scaphoid lesion and filling of void with bone graft provides good functional outcomes.[] The diagnosis could be delayed so proper radiologic investigation and index of suspicion is necessary .Differential diagnoses of painful cystic radiolucent carpal lesion are[]

  • Periodontitis

    A panoramic radiograph showed a well-defined radiolucent osteolytic lesion involving teeth #21-#26. The cortical bone was not affected, and there was no root resorption.[] Both show radiolucency on orthopantomography. It therefore appears reasonable to combine periapical lesions and bone pockets in one subscore.[] […] pockets, and radiolucent lesions in furcation areas.[]

  • Bone Cyst

    Radiographs show a central, well marginated & symmetric radiolucent defect in metaphysis metaphyseal bone does not remodel normally metaphysis is broader than normally seen[] […] jaw fractures and radiolucencies of the jaws.[] British volume. (2002) [ Pubmed ] Cystic radiolucencies of carpal bones, distal radius and ulna as a marker for dialysis-associated amyloid osteoarthropathy.[]

  • Fibroma

    Appearance: - look for well marginated radiolucent lesion, w/ a distinct multilocular appearance; - lesion is usually irregular & is surrounded by reactive rim of bone: -[] From the radiological perspective, the lesion manifests as unilocular, well-demarcated, mixed radiolucent-radiopaque region based on the presence of cementum or bone. [3][] […] line representing a fibrous capsule separates the lesion from the surrounding bone.[]

  • Metatarsal Fracture

    Type III, nonunion Wide fracture line; periosteal new bone and radiolucency; and complete obliteration of the medullary canal at the fracture site by sclerotic bone.[] bone and radiolucency Complete obliteration of the medullary canal at the fracture site by sclerotic bone Several radiographic findings may be confused with fractures of[] Type II, delayed Fracture line that involves both cortices with associated periosteal bone union; widened fracture line with adjacent radiolucency related to bone resorption[]
