Hyperphosphatasemia is a rare disorder of uncertain cause. A 39-year-o
ld male inhibiting striking skeletal deformities consisting of enlarge
ment of the skull, enlargement and bowing of the long bones, neurosens
orial symptoms and elevated alkaline phosphatase is the subject of thi
s report. In the past, the radiological workup has been limited to pla

ymptoms which may complicate this disease.
