 There is a heterogeneously T2 hyperintense, nonenhancing, ovoid lesion in the right frontal white matter measuring 2.1 cm x 1.4 cm in axial dimension and 1.2 cm in coronal craniocaudal height. This is associated with slight heterogeneous T1 hypointensity, however it does not contain foci of susceptibility abnormality, and there is no associated mass effect or edema.There are also small foci of T2 hyperintensity within the right frontal lobe located immediately posteroinferior to the lesion, along the anterior aspect of the internal capsule anterior limb, as well as along the medial aspect of the globus pallidus. These are also nonenhancing and do not contain foci of susceptibility abnormality with no associated mass effect or edema.The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There is no mass effect or midline shift. The pituitary gland is normal in size. There is no evidence for intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. Mucosal thickening is present within the right maxillary sinus which also demonstrates thickened walls suggesting a history of a chronic inflammatory state. Otherwise the remaining paranasal sinuses and mastoid air cells are clear. There is no abnormal enhancement within the brain.
1.There is a heterogeneously T2 hyperintense, nonenhancing, ovoid lesion in the right frontal white matter associated with slight heterogeneous T1 hypointensity, however it does not contain foci of susceptibility abnormality, and there is no associated mass effect or edema.2.There are also small foci of T2 hyperintensity within the right frontal lobe located immediately posteroinferior to the lesion, along the anterior aspect of the internal capsule anterior limb, as well as along the medial aspect of the globus pallidus. These are also nonenhancing and do not contain foci of susceptibility abnormality with no associated mass effect or edema.3.The right frontal lobe lesion may represent a low-grade neoplasm. However, given patient age, in the setting of the other described foci of T2 hyperintensity, the differential diagnosis would also include an inflammatory etiology for all lesions.
