75 Possible Causes for Abnormal Bone Scan, Bone Spicules, 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.[] Cases with remarkably normal-appearing radiographs may show striking abnormalities on radionuclide bone scans and MR images. • As a result, in patients with symptoms but[] Chondroblastoma Rare, normally in epiphysis of long bones - eg, the hip, shoulder and knee.[]

  • Osteosarcoma

    A characteristic ‘sun-ray’ effect of bone spicules is often visible on X-ray.[] PET scan: a full body scan often used to detect cancer biopsy: removal of a tissue sample from the bone for testing bone scan: a sensitive imaging test that shows bone abnormalities[] pain.[]

  • 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[] […] in areas that are abnormal on bone scans.[] Ages range from 39 to 64 years, and reasons for amputation included infection, pain, and necrosis.[]

  • Juxtacortical Osteosarcoma

    Periosteal osteosarcoma is also found of the surface of bone, but has a more spiculed appearance and may appear more aggressive.[] Involutes spontaneously, disappearing/healing NOF has homogeneous sclerosis by 20-30yo, ‘melting’ into the normal bone, can be hot on bone scan.[] Because of the location in the popliteal fossa, the patient may note inability to flex the knee.[]

  • Ewing's Sarcoma

    Uncommon features included epiphyseal involvement (4%), sclerosis (4%), expansion of bone (8%), sunray spiculation (10%), calcification in soft tissue (8%), saucerization[] , and other structures and show details of a tumor or other abnormalities CT scan to image cross-sections of bones and tissues EOS imaging to show the interaction of joints[] Patellar tumors occur infrequently and represent an uncommon etiology of anterior knee pain.[]

  • Osteomyelitis of the Tibia

    […] 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[] The bone scan shows abnormalities earlier than plain x-rays but does not distinguish between infection, fractures, and tumors.[] Her knee pain too, did not abate.[]

  • Ewing Family of Tumors

    It may be spiculated and interrupted - sometimes there is a Codman's triangle.[] Aggressive periosteal reaction This type of periostitis is multilayered, lamellated or demonstrates bone formation perpendicular to the cortical bone.[] A Codman's triangle refers to an elevation of the periosteum away from the cortex, forming an angle where the elevated periosteum and bone come together.[]

  • Bone Tumor

    OSTEOBLASTOMA Definition: - Benign bone forming neoplasm producing woven bone spicules bordered by prominent osteoblasts (osteoid osteoma measuring more than 2.0 cm) Epdemiology[] Bone scan : A bone scan is an imaging study done to detect bone tumors and determine other abnormalities.[] Condition Anterior Knee Pain and Runner's Knee Learn about anterior knee pain, or runner's knee.[]

  • Bone Metastasis

    , and radiating spicules that merge with adjacent trabecula in a feathered pattern [ 12 – 15 ].[] Visualization of osseous lesions is possible since skeletal uptake of technetium-99m medronate is altered in areas of abnormal osteogenesis (bone growth).[] She had knee pain, and I was very slow to recognize that she had metastatic disease in the knee because I was just not thinking that pancreatic cancer would be a primary tumor[]

  • Multiple Myeloma

    This fluid is predominantly blood, but mixed in are bone marrow particles (spicules) which are then spread onto glass slides, stained, and examined by hematologists and pathologists[] Fatigue When the disease progresses, symptoms may include: Fatigue Weakness Broken bones Repeat infections Nausea and vomiting Constipation Difficulty urinating Abnormal bleeding[] CASE REPORT A 56-year-old man with multiple myeloma presented with chronic polyarticular pain and swelling.[]
