Altered mental status, unspecified [R41.82], Reason for Study: ^Reason: assess for seizure focus History: seizure There is relatively well-circumscribed T1 and T2 low signal intensity pituitary fossa mass measured 22.1 mm (RL) X 15.3mm (CC) x 23.9mm (AP) with homogeneous enhancement and slightly eccentric toward left side. Possible diagnosis is pituitary adenoma.There is no evidence of acute ischemic or hemorrhagic lesion.The right PCA territory especially right parahippocampal gyrus and part of right side fusiform gyrus show encephalomalacia indicating chronic ischemic infarction with evidence of ex vacuo changes of the right lateral ventricle temporal horn.The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Pituitary adenoma as described above.2. Chronic encephalomalacia on the right PCA territory as described above.3. No evidence of acute ischemic or hemorrhagic lesion.
