A 54-year-old woman with chronic renal failure presented with tumoral calcinosis manifesting as progressive radiculomyelopathy. Magnetic resonance imaging revealed a spinal epidural mass in the C-2 to C-4 levels. The clinical and radiological findings suggested malignant tumor. Resection of the lesion was performed with total C-2 laminectomy and C-3 and C-4 laminoplasty. The symptoms totally disappeared after surgery. The histological diagnosis was tumoral calcinosis. Tumoral calcinosis is a rare tumoral calcium pyrophosphate dihydrate crystal deposition disease which presents as periarticular soft tissue calcification. Tumoral calcinosis should be considered in patients with a mass lesion involving the upper cervical spine and associated with metabolic abnormalities. Surgical excision is the treatment of choice, because this is completely curative without known recurrence.
