STUDY DESIGN: A case of thoracic spinal cord compression due to tumoral calcinosis (TC) is reported. SETTING: Galiza, Spain. CASE REPORT: A 59-year-old man was admitted to our hospital with a 2-month history of gradual leg weakness and sensory deficit. The neurological examination revealed paraparesis with T12 sensory level. Magnetic resonance imaging (MRI) showed an extradural right posterolateral mass at T11-T12 level, resulting in a marked spinal cord compression. He underwent T11-T12 laminectomy and mass excision. Histological examination finally led to the diagnosis of TC. CONCLUSION: TC is an uncommon cause of mass lesions of the spine. Since there is no typical spine TC MRI appearance, the final diagnosis is done by histological studies. TC should be considered in differential diagnosis of spinal cord compression and constitutes a treatable cause of paraparesis.
