Magnetic resonance (MR) imaging of the cervical spine with axial, low flip angle three-dimensional (3D) gradient-echo sequences is limited by long acquisition times and also by increased sensitivity to extrinsic and intrinsic magnetic field inhomogeneity, magnetic susceptibility differences, chemical shifts, and cerebrospinal fluid pulsatility. We attempted to assess the performance of gadolinium-enhanced, magnetization transfer (MT) prepulsed 3D fast gradient-echo sequences in demonstrating spondylotic changes of the cervical spine. Twenty patients with known cervical spine spondylosis were prospectively imaged in the axial plane using two gradient-echo-based MR techniques: 3D fast field echo (FFE) and gadolinium-enhanced, MT prepulsed, segmented turbo field echo (TFE). An average of 58 neural foramina on the 3D FFE images and 47 neural foramina on the contrast-enhanced TFE images were judged to be narrowed. The degree of neural foraminal narrowing was significantly less on the contrast-enhanced TFE images compared with the FFE images (P <0.001). Contrast-enhanced, MT prepulsed, segmented 3D TFE MR imaging has potential for ameliorating some of the limitations encountered in the more widely used gradient-echo techniques.
Surgical treatment of cervical esophageal cancer is influenced by special problems arising from the anatomical characteristics of this organ. The cervical and thoracic extension of these tumors makes an extensive lymphadenectomy necessary, and radical resections often may only be achieved by laryngectomy. The extent of the resections performed determines the type of intestinal restoration by gastric or colonic interposition and small bowel transplantation. The patient's voice may be preserved by means of tracheopharyngeal shunts with intestinal interposition. The advances of radiation therapy and chemotherapy will enable less extended resections with greater rates of laryngeal preservation.
We describe a 5 year-old girl who had a skin dimple of the back of her upper neck. MRI showed a dermal sinus tract in the upper cervical spine, associated with an intramedullary dermoid cyst at C 2-3, and spina bifida. A laminectomy was performed, the dermoid cyst and the sinus tract were completely removed. This congenital complex is very rare.
