38 Possible Causes for Abnormal Bone Scan, Edema, Narrowing of Medullary Canal

  • Osteomyelitis

    […] in areas that are abnormal on bone scans.[merckmanuals.com] T1 intermediate to low signal central component (fluid) surrounding bone marrow of lower signal than normal due to edema cortical bone destruction T2 bone marrow edema central[radiopaedia.org] Axial computed tomography images of the middle third of the leg bones shaft show periosteal and endosteal bone neoformation that lead to a medullary canal narrowing.[ncbi.nlm.nih.gov]

  • Stress Fracture

    Clinical History: A 61 year old male presents with tibial pain and an abnormal bone scan, suspicious for a possible mass.[radsource.us] Pars interarticularis bone marrow edema (present or absent) was also evaluated on MRI.[ncbi.nlm.nih.gov] medullary canalpropensity for delayed union or nonunion and have ahigh risk of refracture after nonoperative treatment. 34.[slideshare.net]

  • Camurati-Engelmann Syndrome

    The whole body bone scan images showed abnormal increased uptake of the tracer in the long bones of the upper and lower extremities as well as in the skull.[journals.lww.com] […] unpredictable. 16 , 32 It has been hypothesized that those with an intermittent progressive course may be afflicted by repeated acute viral inflammation resulting in neural edema[jamanetwork.com] Certain bone regions (specifically, the endosteal and periosteal surfaces) become abnormally thickened and hardened, which in turn narrows the medullary canal.[encyclopedia.com]

  • Osteomyelitis of the Petrous Bone

    Figure 1: Shows anterior and posterior planar whole body images of a 99m Tc MDP bone scan. Scan shows no obvious abnormality in the skull base region.[ijem.in] Note edema in surrounding bone marrow (*) & soft tissue (arrowheads). Nidus (*) extending to facet cartilage (arrows).[radcharts.org] Diplopia is a result of abducent nerve paralysis caused by compression of the nerve when it passes through Dorelo's canal, owing to the edema present in the petrous apex region[oldfiles.bjorl.org]

  • Radiculomyelopathy

    Bone scan was normal.[thorax.bmj.com] Recurring edema developed mainly in the upper and lower extremities (gluteus, thorax, and face). The duration of edema varied from one day to two weeks.[reliasmedia.com] The spinal cord terminates in the conus medullaris (L1), which then become lumbosacral roots (cauda equina) descending through the lumbar spinal canal.[consultant360.com]

  • Melorheostosis

    CT scan demonstrated abnormalities of both bone density and contour in the lumbar spine.[omicsonline.org] The fact that MRO patients may suffer from edema due to vascular function impairment argues for the latter hypothesis.[symptoma.com] The lesions of the cortex are progressive and may result in narrowing of the medullary canal and stenosis of an adjacent lumen, foramen, or of the spinal canal .[boneandspine.com]

  • Metatarsal Stress Fracture

    […] or osteopenic bone (more common in older patients or young, very thin females).[active.com] After looking at my foot, he was able to pinpoint an exact pt from which the pain was emanating and said something about "edema" and I believe that my foot was somewhat swollen[forum.slowtwitch.com] The narrowing of the medullary canal suggests that this is actually a stress fracture in this location. Figure 5.[aafp.org]

  • Myelopathy

    After a physical examination, your doctor can use a variety of tests to get a closer look, including X-rays, MRIs, CT scans, CT myelogram, or bone scans.[emoryhealthcare.org] Only 1 other patient had a similar "skip lesion," in which the cord edema first appeared in the thoracic cord.[ncbi.nlm.nih.gov] This narrowing in the lower back (lumbar canal stenosis) produces only radiculopathy (pinched nerve) because the tip of the spinal cord called the conus medullaris is at the[necksolutions.com]

  • Lumbar Spinal Stenosis

    ), and spinal instability (abnormal motion between the vertebrae).[medicinenet.com] All patients had past histories of asthma or eosinophilic pneumonia, and four out of five had peripheral edema.[ncbi.nlm.nih.gov] Posterior view of the lumbar region of the spinal canal, demonstrating the conus medullaris at the L1 to L2 level and the cauda equina nerve roots inferiorly.[aafp.org]

  • Narrow Cervical Spinal Canal

    After a physical examination, your doctor can use a variety of tests to get a closer look, including X-rays , MRIs , CT scans , CT myelogram , or bone scans .[emoryhealthcare.org] In cases that may involve bone marrow edema, T2-weighted STIR images are highly sensitive in the detection of marrow edema.[emedicine.medscape.com] TORG's method proposes that the index, smaller or equal to 0.80 identify a significant narrowing of the cervical canal diameter.[scielo.br]
