Female, 10 years old, with history of medulloblastoma, surveillance MRI. Brain:Postoperative findings are redemonstrated in the posterior fossa without significant interval change. The right cerebellar resection cavity is stable in size and morphology. No evidence of pathologic enhancement is seen within or adjacent to the cavity. Scattered foci of susceptibility along the medial margin of the resection cavity are unchanged.No pathologic enhancement is detected intracranially. Nonspecific foci of FLAIR hyperintensity in the right inferior frontal white matter, and the left cerebellum, are unchanged. Likewise, foci of susceptibility within the bilateral temporal lobes are unchanged. No evidence of edema or mass effect is seen. The supratentorial ventricles are normal in size and morphology. Mucosal thickening and secretions are evident in the right maxillary sinus.Spine:A 3 mm focus of susceptibility within the left aspect of the spinal cord at C7-T1 is unchanged. The spinal cord, conus and cauda equina otherwise demonstrate normal signal intensity. No pathologic intrathecal enhancement is seen.Spinal alignment is anatomic. Vertebral body heights are preserved. Fatty marrow replacement throughout the spine is probably related to prior radiotherapy. Otherwise, no pathologic marrow signal abnormality is seen. The intervertebral discs are preserved with no evidence of significant spinal canal or foraminal stenosis.
1.Stable postoperative findings in the posterior fossa with no evidence of tumor recurrence.2.Stable examination of the spine.
