Multiple brown tumors causing spinal cord compression in association with secondary hyperparathyroidism.
Summary of "Multiple brown tumors causing spinal cord compression in association with secondary hyperparathyroidism."
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.

A spinal cord injury encompasses a physical insult to the spinal cord. In the case of anterior spinal cord syndrome, the insult is a vascular lesion at the anterior spinal artery. We present the cases...

Medical and Biotech [MESH] Definitions
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.
Longitudinal cavities in the spinal cord, most often in the cervical region, which may extend for multiple spinal levels. The cavities are lined by dense, gliogenous tissue and may be associated with SPINAL CORD NEOPLASMS; spinal cord traumatic injuries; and vascular malformations. Syringomyelia is marked clinically by pain and PARESTHESIA, muscular atrophy of the hands, and analgesia with thermoanesthesia of the hands and arms, but with the tactile sense preserved (sensory dissociation). Lower extremity spasticity and incontinence may also develop. (From Adams et al., Principles of Neurology, 6th ed, p1269)
