Male, 54 years old, with neutropenic fever and altered mental status in a patient with AML status post stem cell transplant. A small focus of T1 hyperintense material, likely blood, is seen within the left superior frontal sulcus. The edges of the sulcus show susceptibility compatible with hemosiderin staining. Similar findings are also evident along several sulci of the right middle frontal gyrus. These findings are new relative to the prior exam.A few scattered foci of T2 hyperintensity are seen within the periventricular white matter which are not significantly changed from prior. A punctate focus of susceptibility within the left frontal lobe is new and compatible with chronic microhemorrhage.No mass effect or parenchymal edema is detected. The ventricles are within normal limits for size but slightly larger than on the prior examination, a finding which may represent interval volume loss.A mucus retention cyst is present in the right maxillary sinus. Patchy mucosal thickening or secretions are evident in the right frontal sinus and left ethmoid air cells.
1. A small amount of blood product is seen within the left superior frontal sulcus and along some of the sulci of the right middle frontal gyrus. There is no significant associated mass effect or parenchymal edema. No underlying lesions are seen to account for these areas of hemorrhage. Discussed with Dr. Lurain at 8:15 AM on 2/14/15.2. Otherwise no definite evidence of any other acute intracranial abnormality including no findings to suggest acute ischemia or intracranial infection.
