Clinical question: Rule out intracranial mass. Signs and symptoms: Proximal muscle weakness. Nonenhanced head CT:There are few very subtle nonspecific foci of low attenuation in the subcortical white matter of the cerebral hemispheres. Considering patient's age possibility of a small was ischemic disease and demyelinating disease should be considered. Recommend further follow-up with a dedicated brain MRI.There is no evidence of hemorrhage, edema, mass effect or midline shift or hydrocephalus. Calvarium, paranasal sinuses and mastoid air cells are unremarkable.
Very few subtle nonspecific foci of subcortical low attenuation of bilateral cerebral hemispheres. Please follow-up with an MRI exam.
