Figure 1

Schwannoma compressing the left S1 nerve in the left pelvic cavity Male, 52 year, with left lower limb pain. A mass in the left pelvic cavity, which was proved schwannoma pathologically after surgery. Comprared with routine MRI(Figure B,C), MRI 3D-SPACE clearly displayed that the tumor was unconnected with the left S1 nerve but compressed the nerve. The contour of the nerve was continuous and complete(Figure A).

Figure 2

Schwannoma beneath the right psoas major muscle grew along with the right L3 and L4 nerve Male, 70 years with low back pain. A mass beneath the right psoas major muscle was proven to be schwannoma pathologically after surgery. Comprared with routine MRI(Figure B, C), MRI 3D-SPACE clearly demonstrated that the tumor grew along with the right L3 and L4 nerve. The proximal and distal part of the nerver was normal and the contour was continuous and complete(Figure A).

Figure 3

Neurogenic tumor in the paravertebral region grew along with the left L3 and L4 nerve Male, 67 years with left lower limb pain and a medical history of neurofibromatosis-1(NF-1). Multiple lesions in the left paravertebral region. Comprared with routine MRI(Figure B, C), MRI 3D-SPACE distinctly showed that the tumor grew along with the thickening left L3 and L4 nerve. The contour of the nerve was continuous and complete(Figure A).

Figure 4

Metastases in the L2 and L3 vertebral body invaded and wrapped the left L1, L2 and L3 nerve Male,78 years with low back pain and with a medical history of lung cancer. Metastases in the L2 and L3 vertebral body with a soft mass in the left paravertebral region(Figure B, C). MRI 3D-SPACE revealed that the tumor invaded and wrapped the left L1, L2 and L3 nerve. The normal contour，morphology and signal of the nerve disappeared(Figrue A).
