Presentation
Clinical presentation and preoperative work up Nonfunctioning tumors are rare in childhood and children mainly present with endocrinological symptoms. [pediatricneurosciences.com]
With ISG visual disturbances were present in 47% of cases at presentation. In front of SGPA, patient present most frequently acromegalic manifestations (67%), followed by visual manifestations in 29%. [atlasofscience.org]
In children, hypopituitarism commonly presents with delayed puberty or impairment of growth. Diabetes insipidus is rarely a presenting feature but may occur following surgery for a pituitary adenoma. [patient.info]
Hormonal imbalance due to overproduction tends to present earlier and tumors are thus usually small at presentation. This mode of presentation is discussed in the article on pituitary microadenomas. [radiopaedia.org]
Case Presentation A 12-year-old child presented with headaches for 3 months, gradual onset of blurred vision, and strabismus in the right eye. The patient had bitemporal hemianopia and severe vision loss in the right eye on exam. [jaocr.org]
Entire Body System
- Short Stature
Common complaints include headache, increased intracranial pressure, vision changes, short stature and delayed puberty in children, decreased libido, amenorrhea, diabetes insipidus or behavioral changes from tumor expansion and mass effect. [healio.com]
Clinical presentation and preoperative work up They often present with features of raised intracranial tension (ICT) and endocrine dysfunction (delayed puberty, short stature) in children apart from visual impairment which is more common presentation [pediatricneurosciences.com]
Growth hormone-secreting adenomas can increase ICP in a fashion similar to those in children taking growth hormone for short stature or patients with Turner syndrome who develop idiopathic intracranial hypertension. [eyewiki.aao.org]
Respiratoric
- Anosmia
Cerebrospinal fluid rhinorrhea or anosmia can occasionally occur, especially if excessive retraction of the frontal lobe is indicated. 19 Schmidek and Sweet Operative Neurosurgical Techniques Indication [clinicalgate.com]
Anosmia and hyponosmia is a frequent and under recognized minor complication. Fibrosis of neuroepithelium, poor aeration of olfactory receptors, and sinusitis likely contribute. [thamburaj.com]
An undue superior dissection can cause anosmia (44, 92) and can injure the cribriform plate and cause a CSF leak(54). Vertical orientation is best achieved with televised fluoroscopy (30, 36, 52). [pituitary.org]
Musculoskeletal
- Osteoporosis
A prolactinoma is the most common pituitary tumor and may cause amenorrhea, irregular periods, galactorrhea, infertility in women and osteoporosis. It may cause hypogonadism, loss of libido, and impotence in men. [emedicine.medscape.com]
Osteoporosis is present in nearly 40% of patients with Cushing's disease and, pathological fractures are not uncommon. Therefore, care should be taken while positioning these patients. [jnaccjournal.org]

- Diplopia
Patients will often complain that they have trouble with anteroposterior tasks such as cutting fingernails, threading needles, and working with precision tools. [23] Diplopia Diplopia may be due to cranial nerve paresis from lateral extension of tumors [eyewiki.aao.org]
Visual symptoms and signs include vision loss, diplopia, and multiple cranial nerve palsies secondary to rapid expansion of the tumor into the adjacent cavernous sinuses, with cranial nerve III the most commonly affected. [webeye.ophth.uiowa.edu]

Prognosis
Prognosis Surgical good prognosis and the recurrence rate has been reported to be less than 5%. The postoperative outcome of most patients is resolution or improvement of their symptoms. [skullbaseinstitute.com]
In view of this, emergency decompression was planned; however, patients relatives refused surgery due to expected poor prognosis. The patient finally died of cardiorespiratory failure. [ruralneuropractice.com]

Pathophysiology
Pathophysiology Hematogenous metastases to this region most frequently go to the pituitary gland, infundibulum, and tuber cinereum, because these structures lie outside the blood-brain barrier. [radiologykey.com]
The exact pathophysiology of this phenomenon is unknown; however, as most of these lesions involve the chiasm and/or diencephalon, many have proposed that disruption of visual and vestibular input contribute to this pathology. [eyewiki.aao.org]
A thorough understanding of the pathophysiology of the pituitary disease is necessary for the anaesthesiologist to be better equipped to manage these patients in the perioperative period. [jnaccjournal.org]
