 The diffusion and susceptibility images are normal. Nonspecific scattered FLAIR hyperintense foci are seen in the cerebral white matter. No abnormalities are seen in the T1 postcontrast images.There is a thickening and heterogenous appearance of the calvarium. Mucosal thickening and partial opacification of the left maxillary sinus is seen.The right aspect of the clivus demonstrates a lobulated T1 hypointense and T2/FLAIR hyperintense lesion with mild enhancement, corresponding to a focal lucency in this area on CT. This is unchanged in size comparing the most recent CT to that dated 5/7/2013.There is extensive bilateral cervical and left greater than right parotid lymphadenopathy.
1. No acute findings in the brain.2. Cervical and parotid lymphadenopathy, consistent with history of CLL.3. T2/FLAIR hyperintense lesion in the right aspect of the clivus with mild enhancement, with corresponding geographic lucency which has been stable since the CT of 5/7/2013, of uncertain etiology.
