Myeloradiculopathy secondary to pseudogout in the cervical ligamentum flavum: case report.
A case of cervical myeloradiculopathy secondary to deposits of calcium pyrophosphate dihydrate (Ca2P2O7 2H2O) (CPPD) crystals in the degenerating ligamentum flavum, with marked granulomatous inflammation, is presented. This uncommon clinical presentation of pseudogout (CPPD deposition disease) was confirmed after surgical removal of a compressive cervical ligamentum flavum. The diagnosis of CPPD crystal deposition was determined by polarized light microscopy and energy-dispersive x-ray microanalysis in frozen sections of the biopsy specimen. A review of seven previously reported cases along with the present case failed to reveal trauma as a causative factor.
