Abstract
Two cases of cervical radiculomyelopathy were apparently caused by calcification of the ligamenta flava. Similar cases have not previously been described, although myelopathy due to calcified thoracolumbar ligamenta flava is occasionally reported. Radiological study is necessary for diagnosis. Surgical removal of the calcified masses was followed by improvement in the symptoms. In 1 patient, the disease was associated with pseudogout in the menisci of the knee joints, public symphysis, and acetabular lips. The cause and pathogenesis of this rare condition are unknown.
