 The pituitary gland appears small for expected age consistent with hypoplasia or atrophy. There appears to be a nodular area of tissue anterior of the sella which could represent the anterior pituitary. Posteriorly along the infundibulum, there is another small nodular area of tissue which could represent the posterior pituitary. These two areas are separated by a cleft of relatively nonenhancing tissue. Additionally, there is a thin lenticular, likely cystic focus, along the floor of the sella which appears to slightly elevate the pituitary parenchyma. This is best visualized on series 7, image 10. Otherwise, the infundibulum is intact and situated in the midline. The optic apparatus and cavernous sinuses are intact. No diffusion-weighted abnormalities are identified. The imaged intracranial structures are unremarkable. There is partial opacification of the right ethmoid air cells. The remaining visualized paranasal sinuses and mastoid air cells are clear.
1. Small pituitary gland consistent with hypoplasia or atrophy.2. Morphology of the pituitary gland is somewhat unusual, which may simply represent a sequela of hypoplasia, and is notable for a lenticular, possibly cystic focus, along the floor of the sella.3. If patient's outside exam can be made available for comparison, an addendum can be provided.
