Removing Pituitary Tumors in Orange County
A tumor is an abnormal growth of cells that can start anywhere in the body. Tumors that grow in the pituitary gland are called pituitary tumors. Most pituitary tumors are considered benign or non-cancerous because they don’t spread to other parts of the body like cancers do. However, benign tumors can still cause significant health issues because of their location near the brain.
Pituitary adenomas arise from the pituitary gland and are by far the most common growth associated with the gland; they account for 15-20 percent of primary brain tumors. Read more »
Acromegaly is caused by a growth hormone (GH) secreting pituitary adenoma in over 99% of cases. The problems associated with acromegaly include the effects of abnormally high GH and insulin-like growth factor-1 (IGF-1) levels and in some instances by the tumor compressing the normal pituitary gland and optic nerves.

Cushing’s disease is caused by an ACTH-secreting pituitary adenoma. This serious endocrinopathy is a subset of Cushing’s syndrome which refers to elevated blood cortisol levels. Cushing’s syndrome results from tumors of the pituitary, adrenal glands or from tumors elsewhere in the body (ectopic ACTH producing tumors). Read more »

Craniopharyngiomas are benign brain tumors that arise near the Pituitary Gland and Pituitary Stalk and are typically both cystic and solid in structure. They occur most commonly in childhood and adolescence and in later adult life, after age 50. They account for 10-15% of sellar and suprasellar tumors (tumors that occur in and above the pituitary gland) and 50-60% of sellar and suprasellar tumors in children. Read more »
Rathke’s Cleft Cyst are not true tumors or neoplasms; instead they are benign cysts. Rathke’s pouch forms as part of normal development and eventually forms the anterior lobe, pars intermedia and pars tuberalis, of the pituitary gland. This pouch normally closes in fetal development, but a remnant often persists as a cleft that lies between the anterior and posterior lobes of the pituitary gland. Occasionally, this remnant enlarges to form a cyst. RCCs can cause pituitary failure, headaches and in some instances, vision loss. Read more »
Hypopituitarism (pituitary gland failure) is a common consequence of many pituitary tumors and can also result from hemorrhage of a pituitary tumor, radiation to the pituitary gland, pituitary surgery, and from traumatic brain injury. Read more »
