摘要
A 20-year-old vegetarian man was admitted to our hospital complaining of muscle weakness and gait disturbances of 4 years duration. For the past 5 years, he had major depression and had confined himself at home. Fie exhibited tenderness upon palpation of the chest, sternum and proximal muscles. Hypocalcemia, hypophosphatemia, vitamin D deficiency, increased levels of alkaline phosphatase, and intact parathyroid hormone were noted. An x-ray skeletal survey revealed generalized osteopenia, multiple vertebral and costal fractures, and a pelvis deformed into the shape of a triangle. A diagnosis of osteomalacia secondary to vitamin D deficiency from lack of exposure to sunlight and to inadequacy of the diet was made. The patient was started on a treatment with 20,000 IU of vitamin D(3) once a week plus 1 g/d of calcium. Eight months later, gait disturbances have significantly improved and laboratory findings have all normalized.
