History of ALL with nasopharyngeal tumor, radiation to brain and spine: baseline surveillance exam. Brain: There is a right transfrontal Ommaya catheter that appears to terminate in the suprasellar cistern, with mild high T2 hyperintensity in the parenchyma surrounding the catheter that may represent gliosis or edema. The ventricles are otherwise normal in size and configuration. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is no abnormal intracranial enhancement.There is no midline shift or herniation. The major cerebral flow voids are intact. Face: The nasopharyngeal mucosa to be appears intact, without discernible mass lesions.The orbits and salivary glands are grossly unremarkable. There is mild heterogeneity of the sphenoid with predominantly fatty marrow and paucity of the sphenoid sinuses. LIkewise, the right maxillary and bilateral frontal sinuses appear to be non-pneumatized and the left maxillary sinus is hypoplastic.
1. Right transfrontal Ommaya catheter in position with mild surrounding gliosis or edema, but no evidence of acute intracranial hemorrhage, mass, or acute cerebral infarction.2. No evidence of nasopharyngeal mucosal mass lesions.3. Diffusely hypoplastic paranasal sinuses. A sinus CT may be useful for further assessment, if clinically warranted.
