Abstract
This paper discribes two cases of metastatic sacral malignancy causing severe sacralgia, which were surgically treated with a satisfactory result.
Case 1. 67-year-old female suffered from the gait disturbance with a severe buttock pain. CT and MRI demonstrated an osteoclastic tumorous lesion in the sacrum. The tumor was excised with a part of the sacrum. Histologically, the tumor was metastasis of thyroid cancer. Three years after surgery, she has almost normal ADL with a low dose of analgesics.
Case 2. 63-year-old male, who had undergone surgery for rectal cancer 3 years ago, complained of severe sacralgia. In this case also, CT and MRI demonstrated an osteoclastic tumor in the sacrum. With the suggestion of oncologists, the tumor was resected with a distal part of the sacrum. Histological diagnosis was metastasis of rectal cancer. One and a half years after surgery, he has almost normal walking ability without a pain.
As there is no definite strategy for such a metastatic sacral tumor as causing severe sacralgia, the resection of the tumor and a part of the sacrum will be indicated when the remaining life expectancy is considered sufficiently long from the oncologic point of view.
