Massive intratumoral hemorrhage following ventriculoperitoneal shunting procedure in an 8-year-old boy: A case report.

Background: Pineal region tumors comprise 0.4% of all central nervous system tumors in adults and 2.8% in children aged up to 19 years.

Papillary Tumor of the Pineal Gland With Discordant FDG and FAPi Uptake.

In recent years, 68Ga-FAP inhibitor has emerged as a possible substitute radiotracer to FDG for imaging of most of the tumors. Here, we report a 7-year-old girl diagnosed with recurrent papillary tumor of the pineal gland, presenting with complaints of headache and vomiting. 18F-FDG PET/CT revealed an FDG-avid enhancing lesion in the posterior part of the third ventricle.

Long-Term Outcomes of Stereotactic Radiosurgery for Pineocytomas: An International Multicenter Study.

Background And Objectives: Pineocytomas are grade 1 tumors arising from the pineal parenchyma. Gross total resection can potentially cure these benign lesions but can be associated with morbidity. This study was designed to provide multi-institutional data to evaluate the results of stereotactic radiosurgery (SRS) for pineocytomas.

Mediastinal Tumor in a Boy With GnRH-Independent Precocious Puberty and Fluctuating β-HCG Levels.

Gonadotropin-releasing hormone (GnRH(-independent premature puberty in boys, characterized by elevated β-human chorionic gonadotropin (β-hCG) levels, can indicate a secreting germ cell tumor (GCT). These tumors are rare but more common in individuals with Klinefelter syndrome (KS). We present a case of a 7.

Melatonin effect on breast and ovarian cancers by targeting the PI3K/Akt/mTOR pathway.

Melatonin, the hormone of the pineal gland, possesses a range of physiological functions, and recently, its anticancer effect has become more apparent. A more thorough understanding of molecular alterations in the components of several signaling pathways as new targets for cancer therapy is needed because of current innate restrictions such as drug toxicity, side effects, and acquired or de novo resistance. The PI3K/Akt/mTOR pathway is overactivated in many solid tumors, such as breast and ovarian cancers.

Identification of clinical prognosis features and significant DNA methylation regulation in pineoblastoma.

Background: Pineoblastoma (PB) represents a great challenge for clinical management due to lack of a specific therapeutic regimen. This study aims to identify relevant prognostic factors and potential treatment targets by mining public databases.

Methods: The clinical characteristics and survival data of PB patients were obtained from the SEER database between 2000 and 2019 for Cox regression analysis and nomogram construction.

Mature congenital intraventricular intracranial teratoma: A case report and literature review.

Background: Intracranial teratomas represent a rare subset of neoplasms characterized by tissues derived from multiple germ layers within the cranial cavity. These tumors, originating from primordial germ cells, exhibit diverse clinical presentations and histopathological features. While predominantly located along the midline axis, including the suprasellar cistern and pineal region, they can also manifest in less common areas such as ventricles and hypothalamic regions.

Microsurgical Management of Pineal Region Tumors.

Background: Pineal tumors are rare, and the pineal region is a challenging surgical location for neurosurgeons. The present study aimed to investigate the effects of microsurgical management in patients with pineal region tumors and explore probable factors associated with preoperative hydrocephalus, postoperative hydrocephalus remission, and prolonged hospital length of stay (LoS).

Methods: A retrospective study of patients with pineal region tumors who underwent microsurgical management at the First Affiliated Hospital of Soochow University (Jiangsu, China) between 1 January 2010 and 31 October 2022 was conducted.
