Abstract：Objective To evaluate the cause of misdiagnosis and missed diagnosis in patients with intraspinal extramedul-lary tumors. Methods Clinical data of 19 patients with intraspinal extramedullary tumors, admitted to our hospital and misdiag-nosed or missed diagnosis during January 2000 to December 2012, were analyzed. Results The early clinical manifestation was Ra-dicular pain in these patients. The pain was located in lumbosacral portion in 13 patients, 7 patients in lower limbs, 3 patients in neck, shoulder and arm, 1 patient in the chest and abdomen. Some patients had limb numbness, hypoesthesia, and positive patho-logic reflex. Of all of the 19 patients, 14 were misdiagnosed, 5 missed diagnosis. Of the 14 misdiagnosed patients, 5 were misdiag-nosed as muscular strain, 4 as lumbar disc herniation, 3 as cervical spondylosis, and 2 as lumbar spinal canal stenosis. 5 missed di-agnosis patients underwent lumbar discectomy or spinal canal decompression due to complications, and intraspinal extrameduallary tumors were found in 4 cases and 1 missed diagnosis case was later confirmed by MRI. 14 cases of Misdiagnosis had poor treatment effect, MRI examination confirmed the disease in the follow-up. All the patients underwent tumor resection, and the diagnosis was confirmed by pathological diagnosis. Postoperative recovery was good. Conclusion Clinical manifestations of intraspinal extramed-ullary tumor are atypical and tends to be his diagnosed or missed diagnosis. History collection, physical examinations and MR ima-ging are essential in reducing rates of misdiagnosis and missed diagnosis.
