AML status post allo transplant complicated by GVHD, with new altered mental status. There is focus of blooming effect in the right cerebellar hemisphere, which may represent hemosiderin deposition or mineralization. There is scattered periventricular and subcortical white matter T2 hyperattenuation. Otherwise, there is no evidence of tumors or acute infarction. The ventricles and sulci are mildly prominent diffusely due to cerebral volume loss. There is no midline shift or herniation. The pituitary gland appears unremarkable. There is fluid within the bilateral mastoid air cells. There is mild mucosal thickening in the right maxillary sinus and scattered ethmoid air cells. The orbits and calvarium are unremarkable.
1. No abnormal diffusion restriction or acute intracranial hemorrhage.2. Scattered periventricular and subcortical white matter hyperattenuation is nonspecific, but may represent chronic small vessel ischemic disease3. Nonspecific focus of blooming effect in the right cerebellar hemisphere, which may represent hemosiderin deposition or mineralization. 4. Bilateral fluid-filled mastoid air cells, which may represent mastoiditis.
