Brown tumor, a non-neoplastic process resulting from excess osteoclast activity, is found in primary hyperparathyroidism (HPTP) and secondary hyperparathyroidism (HPTS). We report a rare case of multiple spinal cord compression by brown tumors. CASE
A 47-year-old male with end-stage renal disease caused by hypertensive nephrosclerosis, on hemodialysis for 10 years and diagnosed with severe HPTS, developed back pain and sudden onset of gait difficulties progressing to paraplegia. A previous computed tomography (CT) of the lumbosacral spine demonstrated a solid lesion, located in the body of the sacrum, at S1-S2 level, with fine bone edge sclerosis, suggestive of brown tumor. A magnetic resonance imaging without gadolinium injection was performed. The examination revealed an insufflating bone lesion at thoracic level (T5/T6). Posterior laminectomy was followed by tumor excision. Histopathological analysis showed osteoid tissue streaked by fibroplasia with hemosiderin granulation.
Differential diagnosis of sudden neurologic deficits and paraplegia in renal patients with secondary HPPT must consider the possibility of brown tumor.

This is a one-year extension study of the use of laronidase into the spinal fluid to treat spinal cord compression in mucopolysaccharidosis I. Mucopolysaccharidosis I is a rare genetic co...
A benign tumor of the nervous system that may occur sporadically or in association with VON HIPPEL-LINDAU DISEASE. It accounts for approximately 2% of intracranial tumors, arising most frequently in the cerebellar hemispheres and vermis. Histologically, the tumors are composed of multiple capillary and sinusoidal channels lined with endothelial cells and clusters of lipid-laden pseudoxanthoma cells. Usually solitary, these tumors can be multiple and may also occur in the brain stem, spinal cord, retina, and supratentorial compartment. Cerebellar hemangioblastomas usually present in the third decade with INTRACRANIAL HYPERTENSION, and ataxia. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, pp2071-2)
Benign and malignant neoplasms which occur within the substance of the spinal cord (intramedullary neoplasms) or in the space between the dura and spinal cord (intradural extramedullary neoplasms). The majority of intramedullary spinal tumors are primary CNS neoplasms including ASTROCYTOMA; EPENDYMOMA; and LIPOMA. Intramedullary neoplasms are often associated with SYRINGOMYELIA. The most frequent histologic types of intradural-extramedullary tumors are MENINGIOMA and NEUROFIBROMA.
Acute and chronic conditions characterized by external mechanical compression of the SPINAL CORD due to extramedullary neoplasm; EPIDURAL ABSCESS; SPINAL FRACTURES; bony deformities of the vertebral bodies; and other conditions. Clinical manifestations vary with the anatomic site of the lesion and may include localized pain, weakness, sensory loss, incontinence, and impotence.
Neoplasms located in the space between the vertebral PERIOSTEUM and DURA MATER surrounding the SPINAL CORD. Tumors in this location are most often metastatic in origin and may cause neurologic deficits by mass effect on the spinal cord or nerve roots or by interfering with blood supply to the spinal cord.
Pathologic conditions which feature SPINAL CORD damage or dysfunction, including disorders involving the meninges and perimeningeal spaces surrounding the spinal cord. Traumatic injuries, vascular diseases, infections, and inflammatory/autoimmune processes may affect the spinal cord.
Spinal Cord Disorders
The spinal cord is a bundle of nerves that runs down the middle of the back which carry signals back and forth between the body and brain. It is protected by vertebrae, which are the bone disks that make up the spine. An accident that damages the verte...
