X-rays can be used to identify lesions in the brain by showing characteristic patterns associated with various conditions. In the context of skull X-rays, different diseases can present with distinct radiological features:
Paget's Disease: This condition is marked by thickened and deformed bones. On X-ray, it may show as areas of bone sclerosis and irregular thickening. The presence of lytic lesions mixed with sclerosis gives a cotton wool appearance, typical in Paget's disease.
Multiple Myeloma: Appears as multiple punched-out lytic lesions without sclerotic borders. It’s characterized by a "moth-eaten" look on the skull X-rays.
Osteosarcoma: Often associated with aggressive bone lesions and may present as sunburst pattern radiating from the bone surface, more common in long bones.
Osteomyelitis: Involves bone infection that can cause subperiosteal new bone formation and possibly sequestered bone. However, it's more relevant to long bones than the skull.
The question asks which lesions are shown on the X-ray of the skull. The correct answer "Paget's disease" is supported by the described appearance of thickened and deformed skull bones, often with a mixed lytic and sclerotic pattern.
