Female, 61 years old, with a sellar mass seen on prior MRI. Image quality is degraded by motion artifact. A lobular mass is present within the sella and extending into the suprasellar cistern measuring 16 mm CC, 13 mm TV, and 17 mm AP. The lesion is T2 heterogeneous and relatively T1 isointense to brain. The native pituitary gland cannot be recognized as separate from this lesion though artifact and technical factors may contribute.The lesion fills the space between the distal internal carotid arteries, contacting and perhaps partial enwrapping than but without evidence of vascular compromise. The lesion extends superiorly to contact the ACA vessels. The optic nerves appear to be splayed around the lesion. Anteriorly, the lesion appears to extend over the anterior sellar wall and along the planum sphenoidale for a short distance.Right frontal encephalomalacia seen compatible with a chronic infarct. Additional scattered small white matter lesions are seen likely indicating microvascular ischemic disease. Restricted diffusion is again seen in the left middle frontal gyrus.
A mass is present involving the sella and suprasellar cistern. The native pituitary gland cannot be identified as separate from this lesion. Given lack of fine detail deformation due to motion artifact, and without the benefit of IV contrast, macroadenoma or meningioma would be the statistically most likely considerations.
