坐骨神経痛様症状を呈した左大腿骨骨硬化性病変の1例

抄録

We have experienced a case of idiopathic bone infarction of the left distal femur. The patient, a 55-years-old femle caddy, has been suffering from severe pain at the buttock and the pain from thigh to toe during two months. She had the same episode two years ago, but the pain became free within a month.
At first we suspected that the pain was caused by lumbar spinal canal stenosis. In the course of treatment pain was limited at the left knee and there was an osteosclerotic lesion at the distal metaphysis of the left femur on x-ray films. There were no inflammatory signs in the clinical, laboratory and histopathological data. Finally we have found that the pain was caused by the lesion. By the past history, clinical course, signs and histopathological findings, the lesion was diagnosed as idiopathic bone infarction.
