 There is a 3 mm lesion in the left medial frontal lobe subcortical white matter which has a hypointense rim on T2-weighted images with corresponding susceptibility artifact. There is no significant enhancement of this lesion. There is an adjacent developmental venous anomaly within the medial and inferior left frontal lobe. The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There is no mass effect or midline shift. There is no evidence for intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. No diffusion-weighted abnormalities are identified. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. The paranasal sinuses and mastoid air cells are clear. There is no abnormal enhancement within the brain. High-resolution images of the sella demonstrate a partially empty sella with the residual pituitary gland flattened along the bottom of the sella. The pituitary gland enhances heterogeneously without a discrete hypointense focus to confirm a pituitary adenoma. There are no suprasellar or parasellar masses and the cavernous sinuses are symmetric bilaterally.
1. Partially empty sella with heterogeneously enhancing flattened pituitary gland without a discrete focus to confirm a pituitary adenoma.2. Medial left frontal lobe lesion with imaging features compatible with a cavernous malformation and associated developmental venous anomaly.
