Abstract
OBJECTIVE Rathke cleft cysts (RCC) are benign lesions of the sellar region that require surgical treatment in case of visual deterioration or progression of the cyst. However, the natural course is often stable and asymptomatic. We aimed to investigate the characteristics of patients with cyst progression during follow-up (FU) and to compare the natural history of patients with RCC with patients who underwent surgery. METHODS Patients with an MR morphologic cystic sellar lesion classified as RCC between 04/2001 and 11/2020 were included. Functional outcomes, including ophthalmologic, endocrinologic, and MRI data, were retrospectively analyzed and compared between surgically treated patients, patients on a "watch and wait" strategy (WWS), and patients on a WWS who underwent secondary surgery due to cyst progression. RESULTS One hundred forty patients (median age 42.8 years) with RCC on MRI were identified. 52/140 (37.1%) underwent primary surgery. Of 88 patients (62.9%) with initial WWS, 21 (23.9%) underwent surgery for secondary cyst progression. Patients on the WWS had significantly smaller cyst volumes (p = 0.0001) and fewer visual disturbances (p = 0.0004), but a similar rate of hormone deficiencies (p = 0.99) compared with surgically treated patients preoperatively. Postoperatively patients suffered significantly more often from hormone deficiencies than WWS patients (p = 0.001). Patients who switched to the surgical group were significantly more likely to have preoperative T1 hyperintense signals on MRI (p = 0.0001) and visual disturbances (p = 0.001) than patients with continuous WWS. Postoperatively, these patients suffered more frequently from new hormonal deficiencies (p = 0.001). Endocrine and ophthalmologic outcomes in patients with primary and secondary surgery were comparable. Multivariate analysis showed that WWS patients were at a higher risk of requiring surgery for cyst progression when perimetric deficits (p = 0.006), hyperprolactinemia (p = 0.003), and corticotropic deficits (p = 0.005) were present. CONCLUSION Surgical treatment of RCC may cause new hormonal deficiencies, which are rare in the natural course. Therefore, the indication for surgery should be carefully evaluated. Hyperprolactinemia and corticotropic deficits were significant indicators for a secondary cyst progression in patients with RCC. However, a significant amount of almost 25% of initially conservatively managed cysts showed deterioration, necessary for surgical intervention.

J Neurosurg 2023; 138:567-573.

Abstract
OBJECTIVE Incidental, asymptomatic pituitary adenomas require nuanced, shared decision-making, which is limited by a poor understanding of their natural history and effects on quality of life (QOL). A greater understanding of the effects of surgery would inform evidence-based care. METHODS A multicenter review of consecutive pituitary adenomas resected via an endoscopic endonasal approach (EEA) between late 2016 and mid-2021 was performed, with prospective, longitudinal QOL assessment (at 3 and 6 weeks and at 3, 6, and 12 months) postoperatively using the 35-item Anterior Skull Base Questionnaire. RESULTS Of 366 adenomas resected during the study period, 52 (14.2%) were incidentally discovered, of which 51 (98.1%) were macroadenomas. Preoperative QOL in patients with these incidentalomas was better than in those with adenomas presenting with endocrinopathy (p < 0.01), visual failure (p = 0.02), or headache (p = 0.03). Surgery was performed due to visual field deficits (13.5%, n = 7); ophthalmoplegia (1.9%, n = 1); radiological compression or contact of the optic apparatus (63.5%, n = 33); functional status (growth hormone-secreting tumor) (5.8%, n = 3); and clinically significant growth (15.4%, n = 8). Surgical outcomes were excellent, with vision improved in 100% (7/7) and complete resection in 84.6% (44/52). There were 2 (3.8%) cases of new cortisol deficiency, 3 (5.8%) cases of transient postoperative diabetes insipidus, and 4 (7.7%) cases of postoperative hyponatremia. There were no perioperative complications and no cases of postoperative CSF leakage. QOL transiently decreased during the first 3 weeks after surgery, then improved to above baseline levels by 3 months (p = 0.03) and continued to improve throughout the first postoperative year (p = 0.03). All surgical indications demonstrated an overall mean improvement in QOL at 3 months. QOL benefits were not affected by age or tumor size. CONCLUSIONS Resection of pituitary adenomas via the EEA provided a tangible benefit for patients within 3 months. Surgery via the EEA is safe, effective, and beneficial for patients with pituitary incidentalomas meeting accepted criteria for intervention.

Abstract
Patient quality of life (QOL) is an important metric of surgical success. To guide therapeutic advances in pituitary adenoma surgery, a validated, comprehensive instrument to quantify QOL is required. We aim to evaluate the validity of the 35 item anterior skull base questionnaire (ASBQ-35) in patients undergoing pituitary adenoma surgery. A total of 168 patients undergoing endoscopic resection of pituitary adenomas underwent longitudinal QOL assessment using the ASBQ-35 and the 22-item Sinonasal Outcomes Test (SNOT-22) over the first postoperative year. Validity of the ASBQ-35 was assessed by internal consistency, test-retest reliability, responsiveness to clinical change, and concurrent validity with the SNOT-22. Internal consistency of the ASBQ-35 was excellent, with a Cronbach's alpha > 0.95 across all timepoints. Test-retest reliability between 3 and 6 months (ICC = 0.82, p < 0.001) and 6 months and 12 months (ICC = 0.78, p < 0.001) was robust. Concurrent validity with SNOT-22 was strong across all timepoints (absolute Pearson r ≥ 0.63, p < 0.001). Mean ASBQ-35 scores were significantly worse at 3 weeks compared to preoperative baseline (mean difference - 0.28, p < 0.01); however, by 12 months, scores had significantly improved (mean difference + 0.24, p < 0.01), indicating that the scale is responsive to clinical change. Each of the 6 domains of the ASBQ, and all 35 component questions, contributed to the discriminative of the ASBQ to measure QOL during the first postoperative year. The ASBQ-35 is a valid, comprehensive tool for assessing QOL after endoscopic pituitary adenoma surgery. Each component of the ASBQ-35 contributed to the overall assessment of QOL during the first postoperative year.

Abstract
OBJECTIVE Rathke's cleft cysts (RCCs) are relatively common and often detected incidentally. They are usually asymptomatic and managed conservatively. However, little is known about their natural history. Thus, the authors aimed to examine the natural course of RCCs and identify the risk factors for their progression. METHODS This retrospective study examined 229 patients (median age 43.0 years) diagnosed with RCCs by MRI and followed up without surgery (median period 36.6 months). The median cyst height on the initial MRI was 10 mm. Progression or regression of RCC was defined as cyst height changes of ≥ 1 mm. RESULTS In total, 23 (10.0%) RCCs progressed, whereas 73 (31.9%) RCCs spontaneously regressed. The remaining 133 were noted to be stable throughout the follow-up period. Patients with progressed RCCs were significantly older than those with stable RCCs. In patients with acute headache as an initial symptom, RCCs were significantly more likely to spontaneously regress. New symptoms occurred in 6 patients, 5 of whom underwent surgery for RCC progression. Of these 6 patients, 1 patient had persistent adrenocorticotropic hormone deficiency and 1 patient developed diabetes insipidus. Kaplan-Meier analysis results showed RCC progression and new symptom development rates to be 12.0% and 4.1% at 5 years and 13.7% and 5.7% at 10 years, respectively. CONCLUSIONS RCCs rarely progress or cause new symptoms in the long term. Patients with asymptomatic RCC should be followed up for at least 5 years to ensure RCC inactivity. RCCs in older adults may require greater surveillance.
