Objective: To summarize the feature and treatment of the primary intraspinal abscess in order to improve the prognosis.Methods: In the study, 13 cases of primary intraspinal abscess of the recent 20 years were retrospectively analyzed. The history, etiology, pathogen, surgical methods and prognosis were summarized.Results: The course of the illness ranged from 7 days to 6 months. All the cases began with pain. Of the 13 patients, 10 had limb weakness. Five had a fever and 8 had increased white blood cells. As for distribution, 1 was in cervical vertebra, 1 in cervicothoracic junction, 1 in thoracic vertebra, 4 in thoracolumbar junction, and 6 in lumbosacral segment. The results of bacterial culture were positive in 4 cases, 3 cases were diagnosed as tuberculosis by pathological examination, and 1 case was recognized as infection of Brucella melitensis bacteria because of prior brucellosis. The pathogen of the remaining cases were unclear. All the cases received surgical treatment and pathology examination. The surgical aim was mainly removal of the lesion, decompression and drainage. Postoperatively anti-infection and glucocorticoid therapy were performed according to the pathogeny results and clinical experience. Incision abscesses were seen in 2 cases and reoperations including debridement and repair with transferred muscle flap were performed. Postoperative follow-up ranged from 6 months to 3 years (mean 1.8 years). One case suffered postoperative recurrence and the abscess spread along the vertebral canal. Reoperation was performed. Infections of all the cases were recovered completely and the nervous system signs were all improved in different degrees.Conclusion: The onset of primary intraspinal abscess is relatively urgent, mainly with pain. The lumbar and sacral vertebra is the predilection site. The bacterial culture is mostly negative. Early operation and use of sufficient amount of broad-spectrum antibiotic are recommended. If the incision abscess forms after the operation, it is advisable to transfer the muscle flap to repair the coloboma on the basis of debridement. In order to relieve edema of spinal cord and nerve root, the glucocorticoid can be used in the escort of antibiotics.
