==Overview==
Pituitary adenoma must be differentiated from other diseases such as [[craniopharyngioma]], [[meningioma]], [[arachnoid cyst]], and [[pituitary cancer|pituitary carcinoma]].
On the basis of [[seizure]], [[visual disturbance]], and constitutional symptoms, pituitary adenoma must be differentiated from [[oligodendroglioma]], [[meningioma]], [[hemangioblastoma]], [[astrocytoma]], [[schwannoma]], [[Primary central nervous system lymphoma|primary CNS lymphoma]], [[medulloblastoma]], [[ependymoma]], [[craniopharyngioma]], [[pinealoma]], [[Arteriovenous malformation|AV malformation]], [[brain aneurysm]], [[bacterial]] [[brain]] [[abscess]], [[tuberculosis]], [[toxoplasmosis]], [[hydatid cyst]], [[CNS]] [[cryptococcosis]], [[CNS]] [[aspergillosis]], and [[brain metastasis]].

* An elevated concentration of serum [[calcium]] with elevated [[parathyroid hormone]] level is diagnostic of primary hyperparathyroidism.
* Most consistent laboratory findings associated with the diagnosis of secondary hyperparathyroidism include elevated serum [[parathyroid hormone]] level and low to normal serum [[calcium]].
* An elevated concentration of serum [[calcium]] with elevated [[parathyroid hormone]] level in post [[Kidney transplantation|renal transplant]] patients is diagnostic of tertiary hyperparathyoidism.

Overview

On the basis of seizure, visual disturbance, and constitutional symptoms, pituitary adenoma must be differentiated from oligodendroglioma, meningioma, hemangioblastoma, astrocytoma, schwannoma, primary CNS lymphoma, medulloblastoma, ependymoma, craniopharyngioma, pinealoma, AV malformation, brain aneurysm, bacterial brain abscess, tuberculosis, toxoplasmosis, hydatid cyst, CNS cryptococcosis, CNS aspergillosis, and brain metastasis.
