The Various Histopathological Components Of Spinal Tuberculosis In MRI And Its Clinical Significance

Objective Histopathological composition of spinal tuberculosis in theperformance characteristics of the MRI of each treatment period and its outcometo the normal signal.Methods Retrospective analysis of60patients with pathologically provenspinaltuberculosis in patients with MRI data, Collection of preoperative andpostoperative2weeks, after5months and1year postoperatively, more than2years and after different periods of MRI.Its pathological components in MRIsignal performance (in combination with CT) study comparison.Result Vertebral signal begin to change into normal vertebral signal after5months or1year after, most return to normal vertebral signal in two years, notyet into the normal signal vertebral outcome to the normal vertebral signal. In allthe statistics of patients before surgery,49cases of abscesses, all patients have theinflammatory granulation,49cases appear sequestrum,45cases of Cheese-likesubstance,30cases appear empty,45cases of lesions wall is Hardening,15casesof lesions wall is non-hardening,2cases shows a bone bridge formation, Beforesurgery in33cases of spinal cord and nerve root compression,52cases can beseen abnormal disc signal in the preoperative, different degree of stenosis of theintervertebral space, after intraoperative lesions completely removed,decompression and interbody fusion,6cases recurrence,5cases appear abscessand inflammatory granulation,1cases appear abscesses, sequestrum, Cheese-likematerial, inflammatory granulation,2cases of postoperative recurrence of the spinal cord and nerve root compression, The remaining patients returned to normal.Postoperative graft in MRI signal performance began to change after5months or1year after, Most graft2years after the signal is restored to the normal signal,Thissubject can not determine the specific time of graft integration.Conclusion (1) Combined with the observation of CT and MRI beforespinal tuberculosis patients surgery, various pathological components can clear thescreening of spinal tuberculosis, early diagnosis of spinal tuberculosis, found thestuation that lesions involving the vertebral and spinal cord, thorough debridementand decompression provide the basis for the intraoperative.(2) By differentpostoperative period of MRI observed, regardless of how the Vertebral and graftsignal, after positive treatment, the final outcome to the equivalent signal, signaloutcome of recurrence in patients with more postoperative normal and slightlyslower，fewer cases of patients with recurrence，can not form a good control.Thissubject is unable to conclude that the specific time of graft integration.(3) Higherrecurrence rate of spinal tuberculosis, postoperative regularly review the MRI,canearly diagnosis, early treatment, reduce the relapse rate and mortality.
