BACKGROUND: In the treatment of @entity4097 , complete @entity5 resection with complete reconstruction of the spine represents the ideal goal. However, for the treatment of heavily calcified @entity1653 , en-bloc resection of the @entity5 together with the involved dura at the @entity5 base through laminectomy is quite difficult. Conventional laminectomy is not wide enough to allow full exposure of such @entity5 , and postoperative dural defects can cause serious complications. CASE PRESENTATION: A 58-year-old Japanese @entity1 presented with a 3-month history of progressive @entity425 and @entity1183 of the lower extremities. Magnetic resonance imaging (MRI) and computed tomography showed a calcified @entity4097 with dural tail sign at the T10-T11 level, severely compressing the spinal cord anterolaterally. The @entity1 underwent en-bloc resection of the @entity5 with the inner layer of the dura and preservation of the outer layer of the dura through recapping T-saw laminoplasty of T10-T11, including bilateral facet joints. The @entity5 was histologically diagnosed as @entity1653 . Postoperatively, the @entity1 achieved complete recovery of neurological functions. Bone union after laminoplasty was obtained within 6  months. Follow-up MRI at 5  years postoperatively demonstrated no recurrence of the @entity5 . CONCLUSION: Resection of @entity1653 with only the inner layer of dura can minimize @entity260 , including spinal fluid leakage. Recapping T-saw laminoplasty provides extensive exposure for @entity5 removal. The combination of these techniques may offer an ideal surgical option for complete resection of @entity1653 with complete preservation of the posterior spinal elements.
