Abstract
Pituitary apoplexy (PA) may be complicated by development of subarachnoid hemorrhage (SAH). We conducted a literature review to evaluate the rate of PA-associated tumor rupture and SAH. We conducted a systematic literature search (PubMed, Web of Science, Medline) for patients with PA-associated SAH and report a case SAH following PA. Suitable articles, case series, and case reports were selected based on predefined criteria following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). We reviewed included publications for clinical, radiological, surgical, and histopathological parameters.We present the case of a patient with PA developing extensive SAH whilst on the MRI who underwent delayed transsphenoidal resection. According to our literature review, we found 55 patients with a median age of 46 years; 18 (32.7%) were female. Factors associated with PA-related SAH were hypertension, diabetes mellitus, prior trauma, anticoagulant, and/or antiplatelet therapy. The most common presenting symptoms included severe headache, nausea and/or vomiting, impaired consciousness, and meningeal irritation. Acute onset was described in almost all patients. Twenty-two of the included patients underwent resection. In patients with available outcome, 45.1% had a favorable outcome, 10 (19.6%) had persisting focal neurological deficits, 7 developed cerebral vasospasms (12.7%), and 18 (35.3%) died. Mortality greatly differed between surgically (9.1%) and non-surgically (44.8%) treated patients. PA-associated SAH is a rare condition developing predominantly in males with previously unknown macroadenomas. Timely surgery often prevents aggravation or development of severe neuro-ophthalmological defects and improves clinical outcome.

Pituitary function before and after surgery for nonfunctioning pituitary adenomas-data from the Swedish Pituitary Register. Eur J Endocrinol 2023; 189:217-224. [PMID: 37551511 DOI: 10.1093/ejendo/lvad104] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 06/26/2023] [Accepted: 06/30/2023] [Indexed: 08/09/2023]
Abstract
OBJECTIVE Data on pre- and postoperative pituitary function in nonfunctioning pituitary adenomas (NFPA) are not consistent. We aimed to investigate pituitary function before and up to 5 years after transsphenoidal surgery with emphasis on the hypothalamic-pituitary-adrenal axis (HPA). DESIGN AND METHODS Data from the Swedish Pituitary Register was used to analyze anterior pituitary function in 838 patients with NFPA diagnosed between 1991 and 2014. Patients who were reoperated or had received radiotherapy were excluded. RESULTS Preoperative ACTH, TSH, LH/FSH, and GH deficiencies were reported in 31% (236/755), 39% (300/769), 51% (378/742), and 28% (170/604) of the patients, respectively. Preoperative median tumor volume was 5.0 (2.4-9.0) cm3. Among patients with preoperative, 1 year and 5 years postoperative data on the HPA axis (n = 428), 125 (29%) were ACTH-deficient preoperatively. One year postoperatively, 26% (32/125) of them had recovered ACTH function while 23% (70/303) patients had developed new ACTH deficiency. Thus, 1 year postoperatively, 163 (38%) patients were ACTH-deficient (P < .001 vs. preoperatively). No further increase was seen 5 years postoperatively (36%, P = .096). At 1 year postoperatively, recoveries in the TSH and LH/FSH axes were reported in 14% (33/241) and 15% (46/310), respectively, and new deficiencies in 22% (88/403) and 29% (83/288), respectively. CONCLUSIONS Adrenocorticotrophic hormone deficiency increased significantly at 1 year postoperatively. Even though not significant, some patients recovered from or developed new deficiency between 1 and 5 years postoperatively. This pattern was seen in all axes. Our study emphasizes that continuous individual evaluations are needed during longer follow-up of patients operated for NFPA.

Abstract
Prolactinomas are the commonest form of pituitary neuroendocrine tumor (PitNET), representing approximately half of such tumors. Dopamine agonists (DAs) have traditionally been the primary treatment for the majority of prolactinomas, with surgery considered the second line. The aim of this review is to examine the historical and modern management of prolactinomas, including medical therapy with DAs, transsphenoidal surgery, and multimodality therapy for the treatment of aggressive prolactinomas and metastatic PitNETs, with an emphasis on the efficacy, safety, and future directions of current therapeutic modalities. DAs have been the mainstay of prolactinoma management since the 1970s, initially with bromocriptine and more recently with cabergoline. Cabergoline normalizes prolactin in up to 85% of patients and causes tumor shrinkage in up to 80%. Primary surgical resection of microprolactinomas and enclosed macroprolactinomas performed by experienced pituitary neurosurgeons have similar remission rates to cabergoline. Aggressive prolactinomas and metastatic PitNETS should receive multimodality therapy including high dose cabergoline, surgery, radiation therapy (preferably using stereotactic radiosurgery where suitable), and temozolomide. DAs remain a reliable mode of therapy for most prolactinomas but results from transsphenoidal surgery in expert hands have improved considerably over the last one to two decades. Surgery should be strongly considered as primary therapy, particularly in the setting of microprolactinomas, non-invasive macroprolactinomas, or prior to attempting pregnancy, and has an important role in the management of DA resistant and aggressive prolactinomas.

Abstract
INTRODUCTION The integration of sex-related differences in neurosurgery is crucial for new, possible sex-specific, therapeutic approaches. In neurosurgical emergencies, such as traumatic brain injury and aneurysmal subarachnoid hemorrhage, these differences have been investigated. So far, little is known concerning the impact of sex on frequency of postoperative complications after elective craniotomy. This study investigates whether sex-related differences exist in frequency of postoperative complications in patients who underwent elective craniotomy for intracranial lesion. MATERIAL AND METHODS All consecutive patients who underwent an elective intracranial procedure over a 2-year period at our center were eligible for inclusion in this retrospective study. Demographic data, comorbidities, frequency of postoperative complications at 24 hours following surgery and at discharge, and hospital length of stay were compared among females and males. RESULTS Overall, 664 patients were considered for the analysis. Of those, 339 (50.2%) were females. Demographic data were comparable among females and males. More females than males suffered from allergic, muscular, and rheumatic disorders. No differences in frequency of postoperative complications at 24 hours after surgery and at discharge were observed among females and males. Similarly, the hospital length of stay was comparable. CONCLUSIONS In the present study, no sex-related differences in frequency of early postoperative complications and at discharge following elective craniotomy for intracranial lesions were observed.

Abstract
BACKGROUND Transsphenoidal surgery (TSS) remains the treatment of choice for non-functioning pituitary macroadenomas (NFPMA). The value of measuring tumour volumes before and after surgery, and its influence on endocrine outcomes and further treatment of the residual or recurrent tumour are unknown. METHODS Data from patients who underwent endoscopic TSS for a NFPMA (2009-2018) in a UK tertiary centre were analysed for pre- and post-operative endocrine and surgical outcomes. RESULTS Of 173 patients with NFPMA, 159 (61% male) were treatment naïve. At presentation, 76.2% (77/101) had ≥1 pituitary axis deficit. Older age (p = 0.002) was an independent predictor for multiple hormonal deficiencies. Preoperative tumour volume did not correlate with degree of hypopituitarism. Postoperative tumour volume and extent of tumour resection were not predictive of new onset hypopituitarism. Hormonal recovery was observed in 16 patients (20.8%) with impaired pituitary function, with the greatest recovery in the hypothalamic-pituitary-adrenal axis (21.2%, 7/33). A larger residual tumour volume was predictive of adjuvant radiotherapy (3.40 vs. 1.24 cm3, p = 0.005) and likelihood for repeat surgery (5.40 vs. 1.67cm3, p = 0.004). CONCLUSION Pre- and post-operative NFPMA volumes fail to predict the number of pituitary hormone deficits, however, greater post-operative residual volumes increase the likelihood of further intervention to control tumour growth.

Abstract
OBJECTIVE The aim was to study the prevalence of secondary adrenal insufficiency before and after surgery for non-functioning pituitary adenomas, as well as determine risk factors for developing secondary adrenal insufficiency. A secondary aim was to determine adequate p-cortisol response to a 1-μg Short Synacthen Test after surgery. DESIGN Longitudinal cohort study. METHODS One hundred seventeen patients (52/65 females/males, age 59 years) undergoing primary surgery for clinically non-functioning pituitary adenomas were included. P-cortisol was measured in morning blood samples. Three months after surgery, a Short Synacthen Test was performed. RESULTS All tumours were macroadenomas (mean size 26.9 mm, range 13-61 mm). The surgical indications were visual impairment (93), tumour growth (16), pituitary apoplexy (6) and headache (2). Before surgery, 17% of the patients had secondary adrenal insufficiency (SAI), decreasing to 15% 3 months postoperatively. Risk of SAI was increased in patients operated for pituitary apoplexy (p < 0.001), while age, sex, tumour size and complication rate were not different from the remaining cohort. Three months after surgery, all patients with baseline p-cortisol ≥ 172 nmol/l (6.2 μg/dl) and peak p-cortisol during Short Synacthen Test ≥ 320 nmol/l (11.6 μg/dl) tapered cortisone unproblematically. In patients with intact hypothalamic-pituitary-adrenal axis, p-cortisol peaked < 500 nmol/l (18.1 μg/dl) during Short Synacthen Test in 48% of patient. CONCLUSION Pituitary surgery is safe and transsphenoidal surgery rarely causes new SAI. Relying solely on morning p-cortisol for diagnosing secondary adrenal insufficiency gives false positives and the Short Synacthen Test remains useful. A peak p-cortisol ≥ 320 during (11.6 μg/dl) Short Synacthen Test indicates a sufficient response, while < 309 nmol/l (11.2 μg/dl) indicates secondary adrenal insufficiency.

Abstract
PURPOSE The aim of this study was to assess clinical features and therapeutic outcomes in patients with clinically non-functioning pituitary macroadenomas (NFPMAs). METHOD This is a retrospective cohort study of NFPMA patients treated surgically and followed periodically between 2015 and 2017 in a tertiary care center in Iran. Descriptive analysis was performed applying appropriate tests. Binary logistic regression models were used to determine the predictive factors for subtotal tumor resection (STR) and hormonal recovery. Data were analyzed by Stata software. RESULT A total of 71 patients with a mean age of 50.6 ± 1.4 years were studied. The mean diameter of the adenoma was 26.8 ± 1.1 mm. The most frequent symptoms were headache (85.75%), visual field defect (VFD) (78.3%), and hypogonadal symptoms (40.3%). Gross total resection (GTR) was achieved in 45.1%. Preoperative hypopituitarism was observed in 50.7% of patients. Recovery of at least one axis occurred in 36.1% of the patients suffering from hypopituitarism preoperatively, while new-onset postoperative hormonal deficiency appeared in 14.3% of patients. Multivariate analyses showing preoperative tumor size (OR = 38.2; P = 0.008) and cavernous sinus extension (OR = 13.4; P = 0.020) were predictors of STR. Moreover, hormonal recovery was observed not to be related to age, gender, tumor size, or the extent of tumor resection. CONCLUSIONS Tumor size and cavernous sinus extension are the main predictors for STR. Notably, recovery of the gonadal axis in a large proportion of patients supports the surgical resection of NFPAM in patients suffering from gonadal deficiency, even in the absence of VFD.

Abstract
Background The aim of this study was to evaluate the risk factors of gonadal dysfunction among Chinese women of reproductive age with pituitary adenomas (PAs) after trans-sphenoidal surgery. Material/Methods We retrospectively evaluated 317 women (16–44 years old) who underwent gonadal function and hormone testing before and after trans-sphenoidal surgery for PAs during 2003–2012. Gonadal function was assessed on the basis of menstrual status. Results Three women were excluded because of pre-existing gynecological diseases. Before trans-sphenoidal surgery, 34 (10.7%) women were eugonadal and 283 (89.3%) women had gonadal dysfunction. After trans-sphenoidal surgery, 130/189 (68.7%) women with follow-up menstruation data were eugonadal, and 59/189 (31.2%) women exhibited gonadal dysfunction. In addition, 67.4% women of reproductive age with PAs and gonadal dysfunction were restored by trans-sphenoidal surgery (P<0.01). Postoperative gonadal dysfunction was independently associated with high prolactin level at day 1 after trans-sphenoidal surgery (odds ratio (OR)=1.024; 95% confidence interval (CI)=1.005–1.043; P=0.012) and tumor invasion (OR=5.752; 95%CI=1.618–20.447; P<0.01). Based on the receiver operating characteristic (ROC) curve, prediction of gonadal dysfunction in women of reproductive age after trans-sphenoidal surgery for PAs using prolactin >46.82 μg/L on postoperative day 1 had sensitivity of 88%, specificity of 95%, positive predictive value of 98%, and negative predictive value of 76%, and an area under the ROC curve of 0.701. Conclusions Gonadal dysfunction is very common in Chinese women of reproductive age with PAs and can be effectively restored by trans-sphenoidal surgery. Prolactin >46.82 μg/L at 1 day after trans-sphenoidal surgery and tumor invasion can predict postoperative gonadal dysfunction in these patients.

Younger age is a risk factor for regrowth and recurrence of nonfunctioning pituitary macroadenomas: Results from a single Australian centre. Clin Endocrinol (Oxf) 2017; 87:264-271. [PMID: 28467632 DOI: 10.1111/cen.13365] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2017] [Revised: 04/25/2017] [Accepted: 04/27/2017] [Indexed: 01/31/2023]
Abstract
OBJECTIVE The natural history of nonfunctioning pituitary macroadenomas (NFPMA) after surgical resection is variable, with guidelines unable to define the duration of radiological follow-up. In this first Australian series, we identify risk factors for regrowth/recurrence of NFPMA to assist with guiding recommendations for long-term follow-up. DESIGN Retrospective analysis of all radiotherapy-naïve cases with NFPMA resected between 1995 and 2013. PATIENTS One hundred and twenty-three cases had both ≥2 postoperative scans and ≥12-month follow-up. MEASUREMENTS Regrowth was defined as any sustained increase in diameter of residual adenoma or recurrence as any new adenoma occurring post complete resection on serial pituitary MRI. RESULTS Median follow-up time was 48 months (interquartile range [IQR]: 31-86). Overall regrowth/recurrence occurred in 29% (36/123). Regrowth occurred in 40% (30/76) at a median time of 44.5 months (IQR 22-80) compared to recurrence of 12.5% (6/48; P=.003), occurring at a median time of 48 months (IQR 12-96; P=.7). Further treatment was required in 66.7% and 56.7%, respectively (=1.0). Risk factors for regrowth/recurrence by multivariate analysis were presence of residual disease and younger age at presentation. The longest time for regrowth was 168 months (14 years) and recurrence 156 months (13 years). CONCLUSIONS Presence of postoperative residual adenoma and younger age at presentation are the main predictors of regrowth/recurrence in NFPMA. Long-term serial imaging is required to detect regrowth and recurrence in younger patients and those with residual disease. Most regrowth/recurrences will occur within 10 years of follow-up.

[PMID: 28675669 DOI: 10.1111/imj.13546] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2017] [Revised: 06/22/2017] [Accepted: 06/22/2017] [Indexed: 12/31/2022]
Abstract
BACKGROUND There is evidence that cure rates and complications are influenced by the caseload in neurosurgical centres performing transsphenoidal pituitary surgery. Although Australian centres may perform relatively small numbers of these procedures, there have been few published audits of their performance. AIMS To conduct an audit of surgery for pituitary tumours between 2012 and 2014 in the only public hospital neurosurgical unit in the state of Western Australia. METHODS A retrospective chart review was conducted, with standardised extraction of data relating to indications for surgery, tumour type, procedure and postoperative endocrinological and other outcomes. RESULTS Of 53 patients identified, most (91%) underwent transsphenoidal surgery. Most tumours were non-functioning (71.7%), and most of these extended outside the sella turcica (86.8 vs 73.3% of functioning tumours). There was complete removal in 43.4% of patients and evidence of biochemical cure in 33.3% of functioning tumours, but readmission for further surgery was infrequent (5.7%). Persistent cerebrospinal fluid leakage, photophobia and deep venous thrombosis occurred in <4% of patients. There were no deaths. There was a relatively high rate of permanent diabetes insipidus (DI) (13.2 vs <5% in published series), while the frequency of new postoperative anterior pituitary dysfunction (9.4%) was within the range reported in the literature (3-14%). CONCLUSION The outcomes of pituitary surgery in this audit were largely comparable to those reported from other neurosurgical units in Australia and other countries. The increased risk of permanent postoperative DI may reflect the high proportion of non-functioning tumours with extension outside the sella turcica.

Abstract
OBJECTIVE Previous studies have reported recovery of secondary adrenal insufficiency (SAI) in patients with pituitary disorders, generally immediately after pituitary surgery; however, data regarding recovery of long-term SAI are lacking. We conducted a study to assess the longer term recovery rate of SAI in patients with pituitary disorders. METHODS We identified all SAI patients in the Halifax Neuropituitary Database from 1 November 2005 to 30 September 2014, who had required glucocorticoid therapy for ≥3 months, and had a minimum follow-up of 6 months. Patients with ACTH-secreting adenomas, those receiving glucocorticoids only in the routine peri-operative period for pituitary surgery and those on glucocorticoids for nonpituitary conditions were excluded. SAI was defined as either basal serum cortisol < 130 nm and/or a subnormal cortisol response to ACTH-(1-24) stimulation test or insulin tolerance test response. RESULTS Fifty-one patients fulfilled the criteria. Nine (17·6%) patients had complete recovery of SAI over a median of 20 months (range: 8-51) after initiating glucocorticoid replacement. Patients with smaller tumour size had increased likelihood of hypothalamic-pituitary-adrenal (HPA) axis recovery, whereas those with secondary hypogonadism or growth hormone deficiency were less likely to recover. Those with initial cortisol >175 nm had an almost one in two chance of recovery. CONCLUSION Results from our study show that approximately one in six patients with SAI recover adrenal function, even up to 5 years after diagnosis. We recommend that patients with SAI undergo regular testing to assess recovery in order to prevent unnecessary glucocorticoid therapy.

Sheehan MT. Biochemical Testing of the Thyroid: TSH is the Best and, Oftentimes, Only Test Needed - A Review for Primary Care. Clin Med Res 2016; 14:83-92.

Abstract
Disorders of thyroid function are common, and screening, diagnosis, and management are often performed by primary care providers. While management of significant biochemical abnormalities is reasonably straight forward, laboratory tests only slightly outside, or even within, the normal range are becoming more difficult to appropriately manage. A large part of this increasing difficulty in appropriate management is caused by patients requesting, and even demanding, certain tests or treatments that may not be indicated. Symptoms of thyroid dysfunction are non-specific and extremely prevalent in the general population. This, along with a growing body of information available to patients via the lay press and internet suggesting that traditional thyroid function testing is not reliable, has fostered some degree of patient mistrust. Increasingly, when a physician informs a patient that their thyroid is not the cause of their symptoms, the patient is dissatisfied and even angry. This review aims to clarify the interpretation of normal and mild abnormalities of thyroid function tests by describing pituitary-thyroid physiology and through an in depth review of, arguably, the three most important biochemical tests of thyroid function: TSH, free T4, and anti-TPO antibodies. It is important for primary care providers to have an understanding of the shortcomings and proper interpretation of these tests to be better able to discuss thyroid function with their patients.

Abstract
CONTEXT The optimal management of nonfunctioning pituitary adenomas presenting without symptomatic mass effect remains uncertain. The objective of this study was to elucidate the natural history of nonfunctioning pituitary adenomas managed conservatively. DESIGN Volumetric evaluation of tumour growth in serial pituitary MRI scans by a single observer and retrospective review of changes in pituitary function. PATIENTS Patients with nonfunctioning pituitary adenomas who underwent at least 2 serial pituitary MRI scans over ≥6 months between 2003 and 2013 prior to any intervention. MEASUREMENTS Primary end-point was a ≥20% increase in volume or surgery. Secondary end-points were rate of pituitary dysfunction and pituitary apoplexy. RESULTS Fifty nonfunctioning pituitary adenomas (23 macroadenomas and 27 microadenomas, mean age 49, range 17-85 years) were identified. Mean follow-up was 36 months (range 6-79). An increase in volume occurred in macroadenomas (P < 0·01) but not in microadenomas (P = 0·44). A ≥20% increase in volume occurred in nine of 23 macroadenomas compared with two of 27 microadenomas (P < 0·05). Five macroadenomas (one with new visual field defect) and one microadenoma proceeded to surgery (P = 0·08). Hormone deficiency was present in four of 24 macroadenomas vs 0 of 27 microadenomas (P < 0·05) at baseline, while new hormone deficiency developed in only two macroadenomas during follow-up. Pituitary apoplexy occurred in one microadenoma. A growth rate of >10 mm3 /month assessed at approximately 2 years of follow-up among the macroadenoma group was highly predictive (sensitivity and specificity of 90%) of a ≥20% increase in volume or surgery. CONCLUSIONS Nonfunctioning pituitary macroadenomas have a greater tendency to grow and require surgical intervention while microadenomas rarely progress.

Recovery rate of adrenal function after surgery in patients with acromegaly is higher than in those with non-functioning pituitary tumors: a large single center study. Pituitary 2015; 18:701-9.

Abstract
PURPOSE To compare hypothalamus-pituitary-adrenal (HPA) axis integrity at diagnosis and recovery after transsphenoidal surgery (TSS), in acromegaly patients, compared with tumor size matched non-functioning adenoma (NFA) patients. METHODS A retrospective 7-year evaluation of acromegaly patients, who underwent TSS with 52 weeks follow-up at a single institution, was undertaken. 50 acromegaly with complete follow-up data at all points and 50 NFA patients were matched for tumor size; HPA axis was similarly assessed pre-operatively and at 6, 12 and 52 weeks post-operatively. Recovery of HPA axis and gender specific prevalence of adrenal insufficiency (AI), were analyzed in both groups. We also studied AI in acromegaly patients requiring medical therapy post-operatively vs those in remission after surgery. RESULTS AI remained less prevalent in acromegaly vs NFA (acromegaly, p = 0.01; NFA, p = 0.15) at 52 weeks after surgery, although the prevalence of AI decreased in both groups from baseline by 52 weeks. Additionally, recovery from baseline AI was significantly greater by 52 weeks in acromegaly patients over NFA patients (p = 0.001). Recovery of HPA axis in acromegaly patients remained significant (p = 0.03) despite the need for medical therapy. AI at baseline was proportionately more prevalent in acromegalic males at baseline (p = 0.002) but no gender difference was apparent at 52 weeks (p = 0.35). Conversely, in NFA patients, no gender difference was apparent pre-operatively (p = 0.49), but AI was more prevalent in males at 52 weeks (p = 0.001). CONCLUSION In the longest comparative study to date using a standard assessment modality, HPA axis recovery was more frequent in acromegaly compared to NFA patients, independent of tumor size, cavernous sinus invasion (CSI), and body mass index (BMI). HPA axis integrity must be carefully and periodically monitored in acromegaly patients during short- and long-term follow-up to prevent overtreatment with glucocorticoids.

Abstract
Pituitary adenoma (PA) is a common benign neuroendocrine tumor; however, the incidence and proportion of hormone-producing PAs in Korean patients remain unknown. Authors analyzed 506 surgically resected and pathologically proven pituitary lesions of the Seoul National University Hospital from 2006 to 2011. The lesions were categorized as: PAs (n = 422, 83.4%), Rathke's cleft cysts (RCCs) (n = 54, 10.6%), inflammatory lesions (n = 8, 1.6%), meningiomas (n = 4), craniopharyngiomas (n = 4), granular cell tumors (n = 1), metastatic renal cell carcinomas (n = 2), germinomas (n = 1), ependymomas (n = 1), and unsatisfactory specimens (n = 9, 1.8%). PAs were slightly more prevalent in women (M: F = 1:1.17) with a mean age of 48.8 yr (9-80 yr). Immunohistochemical analysis revealed that prolactin-producing PAs (16.6%) and growth hormone-producing adenomas (9.2%) were the most common functional PAs. Plurihormonal PAs and nonfunctioning (null cell) adenomas were found in 14.9% and 42.4% of patients with PAs, respectively. The recurrence rate of PAs was 11.1%, but nearly 0% for the remaining benign lesions such as RCCs. 25.4% of patients with PAs were treated by gamma-knife after surgery due to residual tumors or regrowth of residual tumor. In conclusion, the pituitary lesions and the proportions of hormone-producing PAs in Korean patients are similar to those of previous reports except nonfunctioning (null cell) PAs, which are unusually frequent.
