A bone island, technically known as enostosis, is usually asymptomatic, according to National Center for Biotechnology Information. Asymptomatic means enostosis has no known symptoms, and the condition reveals itself during a bone scan performed for other reasons. Bone islands are benign, notes Orthopaedics One.Continue Reading
Enostosis is marked by a spot of compact bone within that of spongy bone. The benign spot forms during the bone's development or congenitally, and bone islands are believed to occur during the layering of new bone tissue, notes Skeletal Radiology. Bone islands typically occur in the pelvis, femur, ribs and other long bones.
In radiological scans, bone islands appear as lesions between 2 millimeters and 2 centimeters in diameter, according to Orthopaedics One. MRIs typically show no destruction of surrounding tissues with regards to enostosis lesions. Doctors may monitor bone islands for growth later. If the spot enlarges 25 percent in six months or 50 percent in one year, a closer examination of the bone island may be needed.
Multiple bone islands in the same area are collectively called osteopoikilosis, notes Radiopaedia. Bone islands more than 2 centimeters in diameter are known as giant bone islands as these structures may show slow growth over time. Large enostoses may interfere with diagnosing malignancies in known cancer patients, and these large spots may be confused with other bony growths or bone tumors during the initial radiological scans.Learn more about Diagnostics & Imaging
A list of common and relatively rare bone diseases and disorders is presented online at the National Center for Biotechnology Information of the United States National Library of Medicine. The most commonly occurring among these conditions include osteoporosis, fractures, Paget's disease, osteogenesis imperfecta, sclerosis, bone tumors and oral bone diseases.Full Answer >
Symptoms of cervical subforaminal stenosis headaches include pain in the upper cervical area and lower back area of the skull, according to the National Center for Biotechnology Information. Interruptions in memory, concentration, libido and potency may occur as the condition worsens. Symptoms resembling secondary chronic myelopathy can appear. Those symptoms include neck pain, loss of coordination and balance, and numbness and weakness in the arms and hands, notes the American Academy of Orthopaedic Surgeons.Full Answer >
A peripheral giant cell granuloma is an oral cell lesion that normally emerges as a purplish-red nodule consisting of giant cells with more than one nucleus, states the National Center for Biotechnology Information. Although the cause of the granuloma is not definitively known, trauma and local irritation may stimulate its growth.Full Answer >
Side effects of platelet-rich plasma therapy injections include slight pain, pinpoint bleeding and redness, according to the National Center for Biotechnology Information. Since physicians obtain platelet-rich plasma from patients' own blood, the chances of adverse reactions are slim, notes the American Orthopaedic Foot & Ankle Society.Full Answer >
