13-year-old male with history of lesion of the medulla oblongata s/p chemotherapy Off therapy evaluation MRI brain:Redemonstrated is an approximately 30 x 14 mm sagittal dimension medullary lesion which is heterogeneous yet predominately hyperintense on T2 weighted imaging, slightly hypointense on T1, with no convincing contrast enhancement.The CSF spaces are appropriate for the patient's stated age with no midline shift. There are no diffusion abnormality. There are no extra-axial fluid collections. Normal vascular flow voids are present. Sporadic foci mucosal of thickening can be found within bilateral ethmoid and right sphenoid sinuses with near complete opacification of the right maxillary sinus. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.MRI cervical spineThe cervical vertebral bodies are appropriate in overall alignment and height. The cervical spinal cord has normal signal characteristics and overall morphology. No abnormal enhancing lesions are identified in the cervical spine.At C2-3 there is no significant compromise to the spinal canal or neural foramina.At C3-4 there is no significant compromise to the spinal canal or neural foramina.At C4-5 there is no significant compromise to the spinal canal or neural foramina.At C5-6 there is no significant compromise to the spinal canal or neural foramina.At C6-7 there is no significant compromise to the spinal canal or neural foramina.At C7-T1 there is no significant compromise to the spinal canal or neural foramina.The vertebral artery flow voids appear intact.
1.Stable mass in the medulla oblongata2.Unremarkable contrast-enhanced cervical spine MRI without evidence of involvement from the patient's lesion in the medulla.
