Abstract
Introduction: Pseudopseudohypoparathyroidism (PPHP) is a condition of physical features called Albright's hereditary osteodystrophy (AHO) accompanied by mental retardation. PPHP shows various bone lesions with osteophytes and ligamentous ossification of the vertebral body that causes spinal canal stenosis.
Case Report: A 72-year-old woman visited our hospital because of neurological symptoms in the extremities and gait disturbance due to spinal nerve compression. Imaging findings showed spinal canal stenosis due to osteophytes at the atlas level, and narrowing of the spinal canal due to osteophytes, and ligamentum flavum ossification at the thoracic level. The ataxic gait disturbance worsened and required a wheelchair. Surgery was performed after admission. It included decompression of lesions at the atlas level and decompression with implant fixation of thoracic lesions. The postoperative course was good, and the patient was able to walk with a cane at the time of discharge.
Conclusions: We report a clinical case of PPHP with the narrowing of multiple spinal canals owing to the ossification of the ligamentum flavum.
