Pineal cysts without hydrocephalus: microsurgical resection via an infratentorial-supracerebellar approach-surgical strategies, complications, and their avoidance. Neurosurg Rev 2022; 45:3327-3337. [PMID: 35829978 PMCID: PMC9492705 DOI: 10.1007/s10143-022-01831-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 06/28/2022] [Accepted: 06/30/2022] [Indexed: 02/03/2023]
Abstract
Indications for surgery of pineal cysts without ventriculomegaly are still under debate. In view of the limited data for pineal cyst resection in the absence of hydrocephalus, and the potential risk of this approach, we have analyzed our patient cohort focusing on strategies to avoid complications according to our experience in a series of 73 pineal cyst patients. From 2003 to 2015, we reviewed our database retrospectively for all patients operated on a pineal cyst. Furthermore, we prospectively collected patients from 2016 to 2020. In summary, 73 patients with a pineal cyst were treated surgically between 2003 and 2020. All patients were operated on via a microscopic supracerebellar-infratentorial (SCIT) approach. The mean follow-up period was 26.6 months (range: 6-139 months). Seventy-three patients underwent surgery for a pineal cyst. An absence of enlarged ventricles was documented in 62 patients (51 female, 11 male, mean age 28.1 (range 4-59) years). Main presenting symptoms included headache, visual disturbances, dizziness/vertigo, nausea/emesis, and sleep disturbances. Complete cyst resection was achieved in 59/62 patients. Fifty-five of 62 (89%) patients improved after surgery with good or even excellent results according to the Chicago Chiari Outcome Scale, with complete or partial resolution of the leading symptoms. Pineal cysts resection might be an indication in certain patients for surgery even in the absence of ventriculomegaly. The high percentage of postoperative resolution of quality-of-life impairing symptoms in our series seems to justify surgery. Preoperatively, other causes of the leading symptoms have to be excluded.

Abstract
OBJECTIVEPineal region tumors are a rare and heterogeneous group of lesions. The optimal therapeutic approach is currently a topic of controversy, particularly in light of the potential operative risks and complications. The potential beneficial effects of surgery have already been described, but information about neurological outcome and, in particular, health-related quality of life (HRQOL) is still lacking in the literature. The aim of this study was to assess the therapeutic effect of resection of pineal region lesions, emphasizing grade of tumor resection, neurological outcome, quality of life, and the necessity of additional shunt procedures.METHODSThe authors performed a prospective study of HRQOL in 32 patients who had undergone surgical treatment of lesions in the pineal region (20 tumors and 12 cysts) between 2008 and 2014. All patients had at least 6 months of follow-up, with reexamination including standardized neurological assessment, an evaluation of dependency using the modified Rankin Scale, and an evaluation of HRQOL. The authors retrospectively examined patient charts and collected information regarding imaging studies, neurological status prior to surgery, surgical strategies used, any complications, and histological diagnoses.RESULTSIn this study, there was no surgery-associated mortality or major morbidity. Permanent minor morbidity was reported for 4 patients (13%). Comparing pre- and postoperative neurological symptoms, 75% of tumor patients had either complete resolution or improvement of preoperative symptoms; symptoms were unchanged in 10% of tumor patients and deteriorated in 15%. In patients with pineal cysts, long-term follow-up showed that 42% of patients were free of any symptoms and 58% experienced improvement of their preoperative symptoms. These outcomes were also reflected in the modified Rankin Scale scores, which demonstrated significant improvement following resection of pineal region lesions. Furthermore, significant improvements in HRQOL scores occurred in global health status, in all functional scales, and in pain, nausea and vomiting, fatigue, and insomnia (p < 0.0001). Moreover, a significant reduction in the necessity for permanent shunt procedures was observed after gross-total tumor resection compared with subtotal resection (p = 0.035) of pineal cysts.CONCLUSIONSDespite potential risks, (radical) surgery is a highly effective and safe treatment option for pineal region lesions and should be considered for the majority of patients.

Abstract
INTRODUCTION Pineal region glioblastomas (GBM) are very rare, with approximately 46 cases described in the literature. The epidemiology, pathogenesis, and treatment of these lesions are poorly characterized. METHODS We identified all cases of pineal region GBM treated surgically at our institution between 1990 and 2017. Demographic and clinical follow-up data were extracted from the medical records for all cases. Pathology was reviewed and classified according to 2016 World Health Organization (WHO) criteria. Specific attention was given to the frequency of histone H3 K27M mutations in these midline gliomas. RESULTS Eight patients (seven men, one woman) with pineal region GBM, WHO grade IV, were identified. The most common presenting symptoms were headache (75%), vision changes (75%), and gait imbalance/ataxia (50%). Median age at diagnosis was 48.5 years (range 36-74 years). Radical subtotal resection, via a supracerebellar infratentorial approach, was achieved in 75% of patients. Review of the surgical pathology revealed seven primary GBMs (including one giant cell GBM) and one pineal region GBM that developed three years after resection of a pineal parenchymal tumor of intermediate differentiation. No cases demonstrated evidence of IDH-1 R132H mutation (N = 6) or 1p/19q co-deletion (N = 3). One case tested positive for the histone H3 K27M-mutation. Targeted exome sequencing of 467 cancer-related genes revealed nonsense mutations in ATRX and NF1. Adjuvant radiation and chemotherapy was employed in 87.5% and 75.0% of patients, respectively. Median overall survival (OS) was 15 months (range 2-24 months) from GBM diagnosis. CONCLUSIONS This study expands the clinical and pathologic spectrum of pineal region GBM, and provides the first report of the genetic landscape of these tumors.

Abstract
Abstract
BACKGROUND: Pineal region tumors are rare intracranial tumors that are more common in children than adults. Surgical management of tumors in this region using a tailored approach is a strategy that enhances extent of resection and neurological outcome.
OBJECTIVE: To review our institutional experience with pineal region tumors in children and adults over the past 10 years.
METHODS: Our institutional pathology database and patient records were retrospectively reviewed for details regarding clinical and radiological presentation, surgical management, extent of resection, morbidity, and neurological outcome. Statistical analysis was performed to assess for variables related to functional outcomes.
RESULTS: Fifty patients were identified as having undergone surgical management of a pineal region tumor with at least 1 year of follow-up. Forty-one percent presented with a Karnofsky Performance Scale (KPS) score of 70 or less, all of whom had concomitant hydrocephalus that required urgent treatment. The following variables were statistically significant to KPS score on admission: age, tumor volume, preoperative hydrocephalus, length of hospitalization (total and intensive care unit), and elevations in serum tumor markers. The median postoperative (2 months) KPS score was 90. The following variables were statistically significant with respect to change in KPS score postoperatively: tumor maximum diameter, KPS score on admission, and intensive care unit length of stay. The specific surgical strategy did not correlate to extent of tumor resection, morbidity, immediate neurological outcome, and progression-free survival.
CONCLUSION: Extent of resection, neurological outcome, and progression-free survival in the patients in our series were not related to the specific surgical approach employed and its perioperative complications.

Abstract
The extensive variety of possible histologic subtypes makes it imperative to establish a tissue diagnosis in patients with pineal region tumors. Management decisions regarding adjuvant therapy, prognosis, and follow-up strategies vary with the histologic diagnosis. Specialized surgical and stereotactic techniques have evolved to provide the neurosurgeon with an array of safe and effective options for obtaining a tissue diagnosis. Advanced microsurgical techniques combined with improved preoperative management and postoperative critical care methods have made aggressive surgical resection a mainstay of management. Aggressive surgical resection has resulted in excellent long-term prognoses for nearly all patients with benign tumors and a large percentage of patients with malignant tumors. However, pineal region surgery remains fraught with potential pitfalls, and these favorable results are dependent on an advanced level of surgical expertise.

Abstract
OBJECTIVE Pineal parenchymal tumors (PPTs) in adults are rare, and knowledge regarding their optimal management and treatment outcome is limited. Herein, we present the clinical results of our series of PPTs other than pineoblastomas managed by stereotactic radiosurgery (SRS) at upfront setting. METHODS Between 1997 and 2014, nine consecutive adult patients with the diagnosis of PPTs, either pineocytoma or pineal parenchymal tumor of intermediate differentiation, were treated with SRS. There were 6 men and 3 women. The median age was 39 years (range, 31-53 years). All of the patients presented with symptoms of hydrocephalus. Endoscopic third ventriculostomy and biopsy was done for initial management. After histologic diagnosis, patients were treated with Gamma Knife with the mean dose of 13.3 Gy (n=3) or fractionated Cyberknife with 32 Gy (n=6). RESULTS After a mean follow-up of 78.6 months (range, 14-223 months), all patients were alive and all of their tumors were locally controlled except for one instance of cerebrospinal fluid seeding metastasis. On magnetic resonance images, tumor size decreased in all patients, resulting in complete response in 3 patients and partial response in 6. One patient had experienced temporary memory impairment after SRS, which improved spontaneously. CONCLUSION SRS is effective and safe for PPTs in adults and can be considered as a useful alternative to surgical resection at upfront setting.

Abstract
Intracranial epidermoid cysts are one of the rare tumors of all intracranial tumors. They represent 0,2 to 1% of intracranial tumors and 7% of tumors in the cerebellopontine angle. The pineal region is exceptionally subject to such kind of tumor. Cushing was the first to report the pineal localization of the epidermoid cyst in 1928. Up to now, 85 cases of pineal epidermoid cyst were cited in the literature. We report a clinical case concerning a 45 years old man who presented an intracranial hypertension during 18 months. The clinical examination found a hemiparesis with a facial hypoesthesis. The MRI showed a process of the pineal region. The patient underwent a surgery with a large resection. The histological examination confirms the epidermoid cyst. Many approaches were described in the literature. The outcome is related to this localization.

Abstract
BACKGROUND Lesions located in the pineal region represent a surgical challenge. Multiple approaches to this region have been described, each with its advantages and disadvantages. We report the first application of the endoscopic supracerebellar infratentorial approach for complete resection of a pineal tumor. Unlike transventricular endoscopy, this technique poses no risk to the fornices and can be applied independent of ventricular size. CASE DESCRIPTION A 21-year-old man sought treatment for diplopia. Magnetic resonance images of brain revealed a heterogeneous, contrast-enhancing mass that originated from the pineal gland. This tumor exerted the mass effect on the tectum and invaded to the bilateral dorso-medial thalamus and hypothalamus but caused no obstructive hydrocephalus. The results of a cytological study of the cerebrospinal fluid, alpha-fetoprotein, and beta-human chorionic gonadotropin were negative. The patient was referred for the surgical work-up. TECHNIQUE The patient was positioned in the semi-sitting position. The supracerebellar infratentoria corridor was accessed through two paramedian burr holes, which provided natural by-gravity cerebellar traction. The excellent illumination and magnification without sacrificing the inferior occipital sinus could be achieved with the aid of the endoscope. The pineal tumor was resected completely via the full-endoscopic approach. Postoperatively, the patient's diplopia resolved completely, and his hospital course was uneventful. CONCLUSIONS Taking the advantages of the endoscope and peculiar supracerebellar infratentoria corridor, we could successfully remove the gross-total tumor without violating the critical neurovascular structures. Moreover, this approach can be performed regardless of the size of the ventricle. Consequently, it is an excellent minimally invasive surgical option for resection of symptomatic pineal tumor.

Abstract
Background: Diverse tumors in the posterior third ventricular region (TPTVR) frequently occur in children. A decade's experience with pediatric TPTVR is presented, focusing on the Indian perspective. Materials and Methods: 25 children (age range: 3-18 years; mean age: 13.32 years; presentation range: 7 days-2.5 years) had clinico-radiological assessment with contrast computed tomography (CT) and magnetic resonance imaging (MRI). The ventricular/lumbar cerebrospinal fluid (CSF) alpha feto protein (AFP)/beta human chorionic gonadotrophin (HCG) estimation was done when radiological suspicion of a germ cell tumor was present. Extent of resection was deemed partial when some tumor mass remained at the end of surgery, near total when <10% was retained over vital neurovascular structures, and total when complete resection was attained. Results: Operations included infratentorial supracerebellar approach (n = 12), occipito-transtentorial approach (n = 2), endoscopic biopsy and third ventriculostomy (n = 1), frontal parasagittal craniotomy, interhemispheric transcallosal subchoroidal approach (n = 2), middle temporal gyrus transcortical transventricular approach (n = 1), fronto-temporo-zygomatic combined transylvian and subtemporal approach (n = 1) and right ventriculoperitoneal shunt and stereotactic biopsy (n = 1). Only CSF diversion was performed for five patients with a small TPTVR. CSF diversion was required in 12 (48%) patients. Tumor pathology included pinealoblastoma (n = 4; one with pineocytic differentiation), nongerminomatous germ cell tumor (NGGCT; n = 3), germinoma (n = 3), pilocytic astrocytoma (n = 2), epidermoid (n = 3) and primitive neuroectodermal tumor (PNET), fibrillary astrocytoma, glioblastoma, teratoma, and meningioma (n = 1, respectively). A patient with neurocysticercosis was diagnosed solely on MRI (four did not undergo biopsy). Fractionated radiotherapy was administered in 13 patients with primary pineal tumors, PNET, NGGCT, fibrillary astrocytoma and glioblastoma. Extent of excision was total in 10 (40%), near total in 5 (20%), partial in 3 (12%) and a biopsy in 2 (8%) patients. Conclusions: Histopathologic characterization of TPTVR is essential prior to their further management. Benign lesions often have a good prognosis following gross total surgical resection. Pure germinomas are highly susceptible to radiotherapy. NGGCTs often have malignant components that require adjuvant therapy following surgery. The advancements in microsurgical techniques have led to gratifying perioperative results in these deep-seated lesions.

Abstract
The authors present a microsurgical technique for the resection of a heterogeneous group of pineal-region tumors and discuss the key points for successfully performing this surgery. Twenty-six consecutive patients with pineal-region tumors were resected by the senior author (H.B.) and analyzed retrospectively. For all 26 patients, the operation was conducted using the infratentorial supracerebellar (ITSC) approach in the sitting (23 patients) or Concorde (three patients) positions. Twenty-five patients had symptomatic obstructive hydrocephalus and were treated with ventricular drainage, a previously inserted ventriculoperitoneal shunt, or an endoscopic third ventriculostomy before undergoing resection of the pineal-region tumor. The gross total removal of the tumor was achieved in 23 patients and subtotal removal was achieved in three patients. The tumors were pathologically diagnosed mainly as pineocytomas (10), pilocytic astrocytomas (6), or pineal cysts (4). Twenty-five of the patients clinically improved after surgery, and there was no mortality. Two patients experienced transient postoperative neurological deterioration: one patient developed Parinaud syndrome, and one patient developed intermittent diplopia. Successful surgery and patient outcome when treating tumors of the pineal region using the ITSC approach requires: (i) preservation of the venous flow of the Galenic draining system; (ii) preservation of the thick bridging veins of the tentorial surface of the cerebellum, especially the hemispheric bridging veins; and (iii) minimizing retraction of the cerebellum during surgery to avoid adverse effects caused by both direct cerebellar compression and disturbance of the venous circulation.

Abstract
OBJECTIVE Accepted surgical strategies to address symptomatic pineal cysts include transventricular flexible or rigid endoscopy and supracerebellar infratentorial or occipital transtentorial microsurgical approaches. We report the first application of the endoscopic supracerebellar infratentorial approach for the complete resection of a pineal cyst. Unlike transventricular endoscopy, this technique poses no risk to the fornices and can be applied independent of ventricular size. CLINICAL PRESENTATION A 37-year-old woman sought treatment for intractable headaches. A thorough evaluation revealed only a pineal cyst exerting mass effect on the tectum but causing no hydrocephalus. A period of nonoperative management was unsuccessful, and the patient was referred for surgery. TECHNIQUE The patient was positioned in the semi-sitting position. The supracerebellar infratentorial corridor was accessed through a burr-hole. The pineal cyst was resected completely via the endoscope. Postoperatively, the patient's headaches resolved completely. CONCLUSION The endoscopic supracerebellar infratentorial approach involves minimal brain retraction, poses no risk to the fornices, allows visualization and avoidance of the Galenic veins, and can be performed regardless of the size of the ventricle. Consequently, it is an excellent minimally invasive surgical option for resection or fenestration of symptomatic pineal cysts.

Abstract
Meningiomas are uncommon tumors in children and either more rarely encountered in the pineal region. We report two cases of meningioma of the pineal region in children. One of these cases was a five years-old girl and the other a one year-old boy. No specific clinical presentation or tomographic examinations findings was identified before treatment, suggestive of a diagnosis of menigioma. The clinical and laboratory features were very similar to the most common tumors of the pineal region. Prior to the surgery, the histology of these tumors was not suspected. Both patients underwent direct surgery and complete removal was achieved by a suboccipital transtentorial approach. The tumors originated from velum interpositum in both cases. At the follow up, one case presented with recurrence six years later, and she underwent a reoperation with total resection without morbidity. Long-term follow up presented no other recurrences.

Abstract
Optimal management of pineal region tumors depends on securing an accurate histologic diagnosis to facilitate management customized to the nuances of specific pathologies. As an initial step, surgical intervention by either stereotactic biopsy or open surgery is necessary to obtain tissue for pathologic examination. Stereotactic biopsy has the benefit of relative ease and minimal morbidity but is associated with greater likelihood of diagnostic inaccuracy compared to open surgery where more extensive tissue sampling is possible. The role of surgical debulking in the management of pineal tumors is clearly defined for some tumors but is less evident for others. Among the one third of pineal tumors that are benign or low grade, complete surgical resection is achievable and constitutes optimal management with excellent long-term recurrence-free survival. The benefits of aggressive surgical resection among malignant tumors are less clear but several studies have correlated degree of tumor removal with improved outcome. Advances in technology, surgical technique, and post-operative care have minimized surgical complications, however all surgical procedures in the pineal region, including both stereotactic biopsy and open surgery, are potentially hazardous. Advanced judgment, experience, and expertise are necessary to achieve rates of success sufficient to justify aggressive management. Management strategies using stereotactic biopsy, endoscopy, and radiosurgery can also provide favorable outcomes in some cases. Selective incorporation of these innovations can be expected to improve the already highly favorable outcome for all pineal region tumors.
