Primary intramedullary melanocytoma presenting with lower limbs, defecation, and erectile dysfunction: A case report and review of the literature

Figure 3 Postoperative positron emission tomography-computed tomography images and the latest review of magnetic resonance imaging. A and B: Coronal positron emission tomography–computed tomography (PET-CT) images; C: Sagittal PET-CT image; D: Sagittal T1-weighted image (TIWI); E: Sagittal T2-weighted image; F: Sagittal TIWI with gadolinium enhancement; G: Axial TIWI with gadolinium enhancement at the T10 level. A-C: There were no abnormal regions with significant hypermetabolism in the whole body; D-G: The tiny residual (orange arrow) maintained stable. The heterogeneous enhancement of residual did not grow up, but the local edema of the spinal cord mitigated apparently.
