| Popis: | Introduction: Calcification of ligamentum flavum (CLF) is an important cause of spinal stenosis and spinal cord compression. CLF does not usually induce immediate quadriparesis. Here we describe a rare case of immediate quadriparesis due to a large calcified mass containing liquids in the ligamentum flavum, which was easily confused with gout crystals. Patient concerns: A 74-year-old Asian male felt progressive bilateral arm and leg weakness. On the fourth day, acute quadriparesis occurred. Diagnosis: Coronal and sagittal computerized tomography (CT) and magnetic resonance imaging (MRI) showed a large circular mass in the left posterior part of the cervical 3/4 spinal canal, protruding into the canal, and occupying one-half of the spinal canal. Interventions: Emergency laminectomy was performed at C3/4 level. The huge cyst was excised and 1 ml of white viscous liquid flowed out. Outcomes: After operation, CT and MRI showed a full laminectomy of C3/4 and complete decompression of the cervical spinal cord. Hematoxylin-eosin (HE) staining showed that large amounts of calcium was deposited around cystic tissues. Five-year follow-up after laminectomy showed good recovery. Conclusion: This case of immediate quadriparesis, caused by a large calcified mass containing fluid, is very rare. It should be at the earliest stage of calcification. Laminectomy is an effective treatment. This calcification was deceptive and was easily confused with gout crystals. It can help to understand the exact pathophysiology of CLF. |
