The authors describe 2 cases of multiple thoracic disc herniations in the level of T5~6, T6~T7, T7~8 and T8~9, T9~10, T10~11. Thoracic disc herniations is rare and occurs in less than 4% of all diseases. Moreover, multiple thoracic disc herniations is very rare and only 7 cases were reported in the literatures, which occurred at two levels in 6 cases and five levels in one case. The lesions were determined by thoracic CT myelogram and MRI study. A microsurgical posterolateral approach made them curative. Surgical instruments such as downbite curette and surgical microscope were essential for successful treatment.
