[1] It may begin at any age before epiphyseal fusion. [2] The most common cause is a non-cancerous (benign) tumor of the pituitary gland, which may cause it to make too much GH, but it can be caused by other underlying conditions (which may cause a pituitary tumor) including Carney complex ; McCune-Albright syndrome ; Multiple endocrine neoplasia type 1 (MEN-1) and type 4; and Neurofibromatosis.

Is transsphenoidal surgery safe?
Transsphenoidal surgery to resect tumors is as safe in children as it is in adults. A transcranial approach is sometimes necessary. As determined by using the GH assays available to date, GH levels should be normalized (< 1 ng/mL for ≥50% of the points measured during the day) in all patients.

What causes gigantism in the brain?
The pituitary gland is located at the base of the brain, and it is the root cause behind this disease. A hypothalamic condition, caused due to the excess activity of the pituitary gland overproduces the growth hormone, and this leads to gigantism . An adenoma of pituitary gland also causes this disease.

Is carpal tunnel syndrome a secondary condition?
Carpal tunnel syndrome is seen in about 60% of patients and is secondary to swelling of the median nerve rather than extrinsic compression. Early-onset osteoarthritis due to incongruent articular surfaces in the hips, knees, and spine may be seen. Kyphoscoliosis has also been reported in association with acromegaly.
What is the difference between Gigantism and Acromegaly?
Gigantism occurs when growth hormone hypersecretion occurs before the fusion of the long bone epiphysis and is characterized by tall stature. Acromegaly occurs when GH hypersecretion occurs after the fusion of the epiphysis leading to large extremities and characteristic facies.
Does acromegaly increase mortality?
Untreated acromegaly has increased mortality as compared to the general population. The major contributors to mortality are cardiovascular disease (60%), respiratory disease (25%), and malignancies (15%). Mortality rates are similar to the general population in patients with controlled GH secretion.
What are the characteristics of acromegaly?
Acromegaly Characteristics. Increased size of extremities: Enlargement of the hands and feet is noted secondary to both bony expansion and soft tissue swelling. Patients often appreciate an increase in ring and shoe size. The extremities have a "dough" like consistency due to the soft tissue swelling.
What is the IGF-1 test?
Biochemical diagnosis: Measurement of IGF-1 level is the initial test for the diagnosis of acromegaly as it is a stable molecule with a half-life of 15 hours. It should be measured in cases where there is clinical suspicion of acromegaly and pituitary masses – normal IGF-1 level rules out acromegaly.
