1/7. Compressive optic neuropathy caused by renal osteodystrophy. Case report.Compressive optic neuropathy with acute or chronic vision loss has been associated with various skull base tumors, aneurysms, graves disease, trauma, and, less commonly, fibrous dysplasia and osteopetrosis. The authors present a case of acute visual deterioration in a 25-year-old woman who had massive calvarial hypertrophy with optic canal stenosis secondary to renal osteodystrophy (uremic leontiasis ossea [ULO]: bighead disease). Significant visual field restoration was achieved with high-dose corticosteroids followed by optic nerve decompression. This is the first case report of cranial neuropathy associated with ULO.- - - - - - - - - - ranking = 1keywords = stenosis (Clic here for more details about this article) |
2/7. Ankylosing spondylitis: a difficult diagnosis in patients on long-term renal replacement therapy.We report the case of a 48-year-old male, whose musculoskeletal manifestations, previously related to long-term renal replacement therapy (RRT), were diagnosed as ankylosing spondylitis when symptoms changed their pattern on daily hemodialysis (DHD). The patient started RRT in 1981; in 1985 he received a cadaver graft, which failed in 1987. Secondary hyperparathyroidism, amyloid geoids, bilateral carpal tunnel syndrome and high aluminium levels were present. musculoskeletal pain, reported since 1986, involved feet, heels, hips, shoulders, hands, spine. Symptoms impairing daily life did not improve after parathyroidectomy. He developed chronic hypotension and recurrent atrial fibrillation. In 1994 and 1998, because of thoracic pain, coronarography was performed (normal on both occasions). In June 2000, DHD was started. Equivalent renal clearance increased from 9-12 to 15-17 mL/min. Well-being remarkably improved. In September 2000, musculoskeletal pain worsened and bilateral Achilles tendinitis occurred. The worsening of musculoskeletal symptoms despite the improvements in well-being and other dialysis related symptoms prompted a re-evaluation of the case. The diagnosis of ankylosing spondylitis was based on: history of plantar fasciitis, bilateral Achilles tendinitis, inflammatory spinal pain with limitation of lumbar spine mobility (positive Schober test), radiological evidence of grade 2 bilateral sacroiliitis, presence of HLA-B27. This diagnosis cast light on the episodes of chest pain, explained by enthesopathy at the costosternal and manubriosternal joints and atrial fibrillation, due to HLA-B27 associated impairment in heart conduction. This case exemplifies the difficulty of differential diagnosis of multisystem illness in patients with long RRT follow-up.- - - - - - - - - - ranking = 0.81keywords = spinal (Clic here for more details about this article) |
3/7. Lumbar spinal stenosis associated with renal osteodystrophy.A case of coexisting lumbar spinal stenosis and renal osteodystrophy is reported. The presence of renal osteodystrophy is known to have predated the onset of neurological complaints. The patient's symptoms were relieved with surgery. Although a causative relationship between renal osteodystrophy and spinal stenosis has not been reported previously, it seems likely in this case.- - - - - - - - - - ranking = 7056.9210102079keywords = spinal stenosis, stenosis, spinal (Clic here for more details about this article) |
4/7. Thoracic spinal stenosis associated with renal osteodystrophy. diagnosis based on magnetic resonance imaging and computed tomography.We describe a case of thoracic myelopathy in a patient with renal osteodystrophy. The patient had chronic renal failure for longer than 20 years and had skeletal changes indicative of renal osteodystrophy, before the onset of myelopathy. association between spinal stenosis and this entity has been documented only once before in the lumbar region. This is therefore the first case of thoracic myelopathy due to severe stenosis in just one vertebra in a patient with renal osteodystrophy, which was documented by computed tomography as well as magnetic resonance imaging and proven by histopathology.- - - - - - - - - - ranking = 5881.7675085066keywords = spinal stenosis, stenosis, spinal (Clic here for more details about this article) |
5/7. Amyloid destructive spondyloarthropathy causing cord compression: related to chronic renal failure and dialysis.Destructive spondyloarthropathy is a recently recognized disease that has not been reported in the neurosurgical literature. It is associated with spinal amyloid deposition in long-term renal failure and dialysis, and it occurs increasingly as the number of dialysis patients and their survival times increase. Clinically, there is a multisegmental and often rapidly progressive radiculomyelopathy that may require emergency stabilization. The radiological features are disc space narrowing with erosion of vertebral end plates and subarticular cysts. The pathological features include deposition of amyloid, which stains with congo red and antibodies to beta-2-microglobulin. We present two cases with clinical, radiological, and pathological features and a review of the literature.- - - - - - - - - - ranking = 0.81keywords = spinal (Clic here for more details about this article) |
6/7. Case report: renal osteodystrophy in association with spinal stenosis in achondroplasia.A 54 year old woman with achondroplasia presented with symptoms of spinal stenosis. Subsequent studies revealed end-stage renal disease with severe renal osteodystrophy that was characterised by radiographs and new bone biomarkers. We speculate that renal osteodystrophy accentuated spinal stenosis, which is a common feature of achondroplasia in adults.- - - - - - - - - - ranking = 7056.9210102079keywords = spinal stenosis, stenosis, spinal (Clic here for more details about this article) |
7/7. spinal cord compression in renal osteodystrophy.A patient undergoing regular haemodialysis for chronic renal insufficiency developed neck pain followed by progressive spinal cord compression due to subluxation at the level C3-4. decompression, laminectomy and osteosynthesis led to an almost complete recovery. A review of all the histological specimens suggested that hyperparathyroidism and not amyloidosis caused the vertebral destruction.- - - - - - - - - - ranking = 0.81keywords = spinal (Clic here for more details about this article) |
