33 Possible Causes for Bone Spicules, Jaw Mass, Knee Pain

  • Malignant Bone Neoplasm

    Sunburst and hair-on-end periosteal formations also are associated with aggressive bone tumors and are radiating spicules of periosteal bone.[] Chondroblastoma Rare, normally in epiphysis of long bones - eg, the hip, shoulder and knee.[] PRESENTATION -PAIN -PALPABLE MASS -PATHOLOGICAL # AGE 10-30 YRS SITE METAPHYSIS OF LONG BONES -DISTAL FEMUR -PROXIMAL TIBIA -OTHERS HUMERUS,RIBS,ILEUM,JAW BONES LUNG - Cannonball[]

  • Osteomyelitis

    […] detached necrotic cortical bone (develops after 30 days) Cloaca formation space in which dead bone resides MR findings Bone marrow hypointense on T1WI hyperintense on T2WI[] Ages range from 39 to 64 years, and reasons for amputation included infection, pain, and necrosis.[] The bone changes are often adjacent to apices of teeth and are restricted to alveolar process in either or both jaws Chronic sclerosing osteomyelitis / diffuse sclerosing[]

  • Necrosis of the Jaw

    Only minimal surgical intervention is recommended to remove any loose bone spicules.[] Aseptic necrosis of the knee is often associated with pain or limping with walking.[] Approximately 125 cases of osteonecrosis of the jaw have been linked with the use of some type of bisphosphonate drug.[]

  • Bone Tumor

  • Osteosarcoma

    A characteristic ‘sun-ray’ effect of bone spicules is often visible on X-ray.[] pain.[] Radiologic work-up revealed a 6.2 cm mass involving the right parotid gland.[]

  • Osteoma

    […] osteoblasts and osteoclasts surrounding sclerotic bone Osteoid osteomas are characterized microscopically by a maze of small spicules of immature bone, most often lined with[] pain but normal clinical examination.[] The peripheral osteoma of the jaw is uncommon.[]

  • Juxtacortical Osteosarcoma

    Periosteal osteosarcoma is also found of the surface of bone, but has a more spiculed appearance and may appear more aggressive.[] Because of the location in the popliteal fossa, the patient may note inability to flex the knee.[] JC involving the jaw usually present as painless mass rapidly growing to a large size, facial deformity, and mobility of the teeth in the involved region.[]

  • Osteoblastoma

    Benign osteoblastoma is a rare bone tumour characterised histologically by the production of woven bone spicules, which are bordered by prominent osteoblasts.[] They present clinically with severe pain in the anterior knee or an obvious growth of soft tissue.[] A 25-year-old man presented with a palatal mass of several months' duration.[]

  • Chondroma

    Due to its higher spatial resolution than MRI, CT is superior for demonstrating characteristic overhanging bone spicules.[] A 16-year-old boy presented with a patellar mass and anterior knee pain without any trauma.[] The patient could know the presence of a mass or have moderate symptoms for several years previous to diagnosis.[]

  • Periostitis

    Diagnostic Tests: Characteristic changes include less dense, new bone formation that is elevated, running parallel to cortical bone and may appear linear, layered, or spiculated[] […] the humeri, knees, femurs, hips, and hands.[] The otolaryngologist should be aware of this entity and include it in the differential diagnosis of any fixed jaw mass to avoid mistaking it for a more malignant process with[]
