Introduction: The role of stereotactic radiosurgery (SRS) in pituitary adenomas (PAs) is evolving especially considering its safety. Existing literature is hampered by limited sample sizes and short-term follow-ups, impeding its preeminence in the clinical and radiological outcomes. We propose a comprehensive, single-centred study to evaluate the outcomes following CyberKnife stereotactic radiosurgery (CK SRS) for PAs in a larger patient population, incorporating meticulous clinical and radiological follow-up.

Radiation has been used to treat meningiomas since the mid-1970s. Traditionally, radiation was reserved for patients unfit for major surgery or those with surgically inaccessible tumors. With an increased quantity and quality of imaging, and an aging population, there has been a rise in incidentally diagnosed meningiomas with smaller tumors at diagnosis time.

Introduction: Stereotactic radiosurgery (SRS) is one of the treatment options for the management of residual or recurrent secreting pituitary adenomas (PA). While the role of radiosurgery (RS) by Gamma Knife (GK) has been clearly established, Cyberknife (CK) RS has been evaluated in fewer series.

Material And Methods: To perform a systematic review of the literature and meta-analysis, with the aim of focusing on the effect of CK RS on secreting PA.

Introduction: Acromegaly is due in almost all cases to a GH-secreting pituitary tumor. GH and IGF-1 excesses lead to its multi-system clinical manifestations and comorbidities. Acromegaly is under-diagnosed and typically presents with advanced disease.

 Pituitary adenoma is the most common disease that affects the gland and may be classified as functional/nonsecretory tumors. Inflammatory/infective causes may also affect the pituitary gland. The 18F-fluorodeoxyglucose positron emission tomography/computed tomography (F18-FDG PET/CT) may have an incremental value in assessing these lesions and in determining their clinical significance.
