317 Possible Causes for Bone Spicules

  • Usher Syndrome Type 1K

    The fundoscopic finding of both eyes showed typical pigmentary degeneration with multiple bone spicule pigmentations in over the entire retina, attenuated retinal vessels,[mafiadoc.com] Temporal bone computed tomography and magnetic resonance imaging showed no specific findings.[mafiadoc.com] On ophthalmologic examinations, the lens and the cornea were intact, but the fundoscopic examination revealed bony spicule pigmentation with attenuated retinal vessels in[mafiadoc.com]

  • Pigmented Paravenous Retinochoroidal Atrophy

    Funduscopic examination revealed bone-spicule pigmentation and choroidal and retinal pigment epithelium atrophy along the vascular arcades, with macular involvement in right[ncbi.nlm.nih.gov] A 68-year-old man with patchy paravenous zones of retinal degeneration with bone spicule pigmentation OU was diagnosed as having pigmented paravenous retinochoroidal atrophy[ncbi.nlm.nih.gov] Pigmented paravenous retinochoroidal atrophy is an ocular disease characterized by outer retina and choroidal atrophy often with overlying intraretinal bone spicule pigment[ncbi.nlm.nih.gov]

Examples of bone spicules.[healio.com]

  • Retinitis Pigmentosa 30

    Within 30 years, the complete clinical manifestation of RP developed with bone spicule-shaped pigment deposits, pale optic disc, narrowed arterioles, cystoid macular oedema[ncbi.nlm.nih.gov] Within 30 years, the complete clinical manifestation of RP developed with bone spicule-shaped pigment deposits, pale optic disc, narrowed arterioles, cystoid macular oedema[casereports.bmj.com] Retinitis Pigmentosa 30 Synonyms MACULAR DEGENERATION, INCLUDED Classification eye, genetic Phenotypes Attenuation of retinal blood vessels ; Autosomal dominant inheritance ; Bone[mousephenotype.org]

  • Osteoblastoma

    Benign osteoblastoma is a rare bone tumour characterised histologically by the production of woven bone spicules, which are bordered by prominent osteoblasts.[ncbi.nlm.nih.gov] Histology confirmed a benign osteoblastoma that was composed of proliferating osteoblasts with woven bone spicules and rich vascular stroma.[ncbi.nlm.nih.gov] Osteoblastomas are benign bone-forming neoplasms that produce woven bone spicules bordered by osteoblasts, histologic features that are similar to those of osteoid osteomas[roentgenrayreader.blogspot.com]

  • Osteoporosis

    The weaker spicules of trabecular bone break ("microcracks"), and are replaced by weaker bone.[en.wikipedia.org] Not only is bone density decreased, but the microarchitecture of bone is also disrupted.[en.wikipedia.org] Because osteoblasts and osteoclasts inhabit the surface of bones, trabecular bone is more active and is more subject to bone turnover and remodeling.[en.wikipedia.org]

  • Retinitis Pigmentosa 26

    There are bone spicules and peripheral pigment degeneration extending inside the arcades, again not much different from the photos in 2003.[retinagallery.com] Fundus revealed arteriolar attenuation and diffuse bone-spicule pigmentation involving the macula [Figure 1] a and [Figure 1] b.[ijo.in] Fundus examination reveals bone spicule pigment deposits, attenuated retinal vessels, retinal atrophy and waxy optic nerve pallor.[orpha.net]

  • Boucher-Neuhauser Syndrome

    Some clumps of pigment deposition (without bone spicule configuration) were also seen. The retinal vessels and optic disc appeared normal ( Fig. 2A, B ).[synapse.koreamed.org] spicules.[disorders.eyes.arizona.edu] The clinical features of Refsum's disease include cerebellar ataxia and retinal dystrophy with pigment changes, bone-spicule formation, optic atrophy, and attenuated retinal[synapse.koreamed.org]
