Is craniopharyngioma a pituitary tumor?
Craniopharyngiomas are benign tumors that grow near the pituitary gland. They can be solid tumors or cysts. Approximately 10-15% of pituitary tumors are craniopharyngiomas. They are most commonly found in children, teenagers, and adults older than 50.
Is craniopharyngioma an adenoma?
Pituitary adenomas are tumors that come from your pituitary gland, and craniopharyngiomas are located near that gland. Although both tumors are considered benign, craniopharyngiomas generally have a more aggressive nature than pituitary adenomas.
Is craniopharyngioma a CNS tumor?
Craniopharyngioma is a rare, virtually benign tumor of the central nervous system (CNS). It is a partly cystic embryonic malformation that can occur in the sellar/parasellar region and can produce a wide array of symptomatology such as headaches, nausea and vomiting, visual disturbances, and endocrine disturbances.
Is craniopharyngioma cystic?
These tumors usually involve the pituitary stalk, the structure that connects the pituitary gland to the hypothalamus and are classically very sticky and adherent tumors. They have varying cystic and solid portions, with the majority having at least some cystic component.
Can craniopharyngioma become malignant?
Many experts consider craniopharyngiomas to be a chronic disease, as they tend to recur even when they have been completely removed (resected) surgically. The tumor itself is usually not dangerous, as it is benign and only very rarely becomes malignant.

Treatment of newly diagnosed childhood craniopharyngioma may include the following: Surgery (complete resection) with or without radiation therapy. Partial resection followed by radiation therapy. Cyst drainage with or without radiation therapy or surgery.
What hormone is deficient in craniopharyngiomas?
Gonadotropin Deficiency Following craniopharyngioma growth, the secondary mass effect can oppress the normal pituitary and stalk and lead to a deficiency of important pituitary hormones such as Gn (73), resulting in delayed puberty in children and hypogonadism in adults (4).
How fast does craniopharyngioma grow?
They are slow-growing tumours that can take two to three years or longer to manifest themselves before a diagnosis is made. They can cause serious problems by interfering with important structures near them.
What are the risk factors craniopharyngioma?
At present, there are no known causes or proven risk factors for craniopharyngioma. Blood and urine tests can indicate a hormone imbalance that may be caused by a problem with the pituitary gland.
Is craniopharyngioma a Suprasellar?
Background: Craniopharyngiomas are benign neoplasms that are usually suprasellar in origin. They are considered a type of pituitary tumor that can cause hyposecretion of anterior pituitary hormones or hypopituitarism. Clinically, they may cause visual and endocrine deficiencies similar to pituitary adenoma.
What is Gonadotroph adenoma?
Gonadotroph adenomas are adenomas that secrete the gonadotropins FSH and LH. Clinically active gonadotroph adenomas are regarded as uncommon tumors; unlike other secreting tumors, gonadotroph adenomas do not usually cause a clinical syndrome related to hormone overproduction.
What is a Somatotroph adenoma?
Somatotroph adenoma is defined as a pituitary neoplasm characterized by unregulated growth hormone (GH) hypersecretion. Typical features such as acral enlargement and coarse facial features identify patients with somatotroph adenomas, leading to a diagnosis of acromegaly.
What is a Corticotroph adenoma?
Corticotroph adenoma is a benign tumor of the anterior pituitary gland that secrets adrenocorticotropic hormone (ACTH) as well as proopiomelanocortin-derived peptides. Corticotroph adenoma is also referred to as: corticotropic adenoma, corticotropinoma, ACTH-producing adenoma, and ACTH-secreting adenoma.

How to treat craniopharyngiomas?
Two main management options have primarily been used: attempt at complete removal (gross total resection), or partial removal (partial resection) followed by radiation therapy to treat residual disease. [6] Advances in techniques used in neurosurgery have made total resection possible in more cases, but improvements in radiation therapy techniques have also made this option more effective and safe. There currently is no firm consensus of opinion regarding the best treatment option. [6] Unfortunately, even following treatment, many people experience endocrine, vascular, neurologic, and/or visual complications. Psychological, social, and emotional problems are also common. [6] [9] Panhypopituitarism (when the pituitary gland does not make most or all hormones) and hypothalamic dysfunction are prevalent and are treated with hormone therapy to replace various pituitary and hypothalamic hormone deficiencies. [5] Early studies suggest that oxytocin (a less understood hormone often not replaced) may benefit some people with certain symptoms of hypothalamic dysfunction such as obesity and behavioral issues; however, additional research on larger groups of people is needed to determine its role in therapy. [9] [5] [10]

What happens if a complete resection is not complete?
If a complete resection (or, gross total resection) cannot be accomplished, then a partial resection (subtotal resection) is done, leaving a small amount of craniopharyngioma behind.
How to treat craniopharyngioma?
The treatment of craniopharyngioma is complex because many factors affect whether the tumor can be removed or prevented from growing. In general, the initial approach is to perform surgery to remove as much of the tumor as possible. Depending on the size and location of the tumor, patients with craniopharyngioma may be a candidate for minimally invasive skull base surgery. This approach involves removing the tumor endoscopically, using special tools and scopes that pass through small openings–in this case, the nasal passages. Because many craniopharyngioma can be removed through the patient’s nose, this type of procedure does not require drilling into the skull, or making facial or scalp incisions. For very large tumors, larger operations (i.e. craniotomy) may be necessary.
What causes a person to lose vision?
Unusual sleepiness. Weight gain. In addition, because the optic nerves (which connect the eyes to the brain) are located above the pituitary gland, craniopharyngioma may cause the following: Progressive loss of vision. Sometimes, very large craniopharyngioma can block normal flow of cerebrospinal fluid in the brain.
What type of radiation therapy is used for a tumor?
The type of radiation used depends upon the location of the residual tumor: If there is a larger amount of tumor remaining after surgery, or if vital structures are close by, then 3D conformal radiation therapy or intensity modulated radiation therapy may be used.
How long does it take to recover from craniopharyngioma?
At ten years after diagnosis, overall survival rates for adult patients with craniopharyngioma are 85-90%. 2. Outcomes are best if the tumor is removed completely or treated effectively with radiation. Depending on how severe the symptoms are at the time of diagnosis, patients can make a complete recovery.
What are the symptoms of a tumor in the brain?
Symptoms: Increased pressure within the brain causes many of the symptoms associated with this tumor. Other symptoms result from pressure on the optic tract and pituitary gland. Obesity, delayed development, impaired vision, and a swollen optic nerve are common .

The ABTA YouTube Channel provides educational videos about tumor types, treatments, and support strategies for newly diagnosed, survivors and caregivers.
How to treat hydrocephalus?
Treatment: Surgery to remove the tumor is usually the first step in treatment. If hydrocephalus (excess water in the brain) is present, a shunt (drainage system) may be placed during surgery. The shunt will help remove excess cerebrospinal fluid from the brain and ease the pressure.
Is Adamantinomatous craniopharyngioma more solid than papillary cranioph?
Adamantinomatous (ordinary) craniopharyngioma occurs in children and tends to be less solid than papillary craniopharyngioma. Papillary craniopharyngioma occurs in adults and is a more solid tumor.

How to remove craniopharyngioma?
To remove the craniopharyngioma using this technique, the neurosurgeon makes an incision in the scalp behind the hairline and removes the bone that forms the contour of the orbit and cheek. Temporarily removing this bone allows the surgeon to access areas of the brain that are more difficult to reach while minimizing severe damage to the brain. The surgeon replaces the bone at the end of the procedure.
