 Images are significantly degraded by motion artifact. There appears to be restricted diffusion in the corpus callosum, which is incompletely evaluated on this examination. There is probably associated increased T2 signal in this region.Dedicated images through the sella demonstrate a 2.2 x 2 x 2.5 cm (AP x TV x CC) mass in the sella/suprasellar region. The mass predominantly shows mildly increased T1 and T2 signal. Lesional enhancement is moderate along its periphery but fades internally. There is expansion of the sella, invasion into the suprasellar cistern and elevation of the optic chiasm. Mucosal thickening is noted in the sphenoid sinuses. A subcentimeter sebaceous cyst is again noted in the left temporal scalp.
1. Apparent diffusion restriction in the corpus callosum is incompletely evaluated. Differential considerations would include recent ischemia or perhaps less likely a demyelinating process among other possibilities. MRI of the entire brain is suggested possibly with sedation to control for motion.2. 2.5 cm sellar/suprasellar mass is favored to represent a macroadenoma versus meningioma. Dr. Sorensen discussed the above findings with Dr. Ganjoo on 9/23/2016 at 1545 hours.
