Mixed germ cell tumor of the pineal gland in a pediatric patient.

Radiol Case Rep 2022 Sep 17;17(9):2940-2945. Epub 2022 Jun 17.

Department of Surgery, Mayo Clinic, Rochester, MN, USA.

Tumors of the pineal region are a rare clinical entity, comprising approximately 3%-8% of pediatric tumors. Based on their histopathological features, they are typically classified as pineal parenchymal tumors and germ cell tumors, with the latter being more prevalent. Clinical presentation is heterogeneous, with symptoms arising either due to tumor invasion or compression of adjacent neurovascular structures and increased intracranial pressure. Read More

Clinical and Radiological Characteristics of Non-Benign Pineal Cyst Lesions in Children.

Front Neurol 2021 20;12:722696. Epub 2021 Aug 20.

Department of Pediatric Neurology, University Children's Hospital, University Medical Centre Ljubljana, Ljubljana, Slovenia.

With the increasing availability and advances in brain imaging, pineal cyst lesions (PCL) are becoming a common finding in the pediatric population. In the absence of evidence-based guidelines, optimal diagnostic and therapeutic approaches have not been established, and there is a risk of under- or overtreatment of these patients. The aim of our study was to evaluate the clinical presentation and radiological features of PCL in a cohort of pediatric patients and to identify clinical parameters more commonly associated with neoplasms in the pineal region.

Mission impossible: chemotherapy in the intensive care for pineal region germ cell tumor.

Childs Nerv Syst 2022 01 20;38(1):179-183. Epub 2021 Jan 20.

Department of Neurosurgery, All India Institute of Medical Sciences, New Delhi, India.

Pineal region tumors are rare and a heterogenous group of primary central nervous system tumors which are primarily classified as germ cell tumors and non-germ cell tumors. Chemotherapy and radiotherapy as the primary treatment modalities have been reported to result in good outcomes. We discuss the case of a young girl who presented to our emergency department in an unconscious state and had a large lesion in the posterior third ventricular region, but without any associated hydrocephalus which could explain her stuporous state.

Lateral Temporal Approach for Image-Guided Stereotactic Biopsy of Pineal Region Tumors.

World Neurosurg 2021 03 9;147:144-149. Epub 2020 Dec 9.

Department of Neurosurgery, Roswell Park Comprehensive Cancer Center, Buffalo, New York, USA; Department of Neurosurgery, Jacobs School of Medicine and Biomedical Sciences, State University of New York, Buffalo, New York, USA.

Background: Biopsy of pineal region neoplasms is frequently accomplished by way of endoscopic transventricular access or using an image-guided, computer-assisted stereotactic approach.

Methods: We evaluated a nonorthogonal lateral temporal approach for stereotactic biopsy of pineal region tumors as a variation of previously described stereotactic methods. Magnetic resonance imaging-guided frameless stereotaxy was used to plan and perform biopsies of pineal region tumors using a nonorthogonal trajectory extending from the superior or middle temporal gyri through the temporal stem, anterior to the atrium of the lateral ventricle, and posterior to the corticospinal tract.

Pediatric Suprasellar Germ Cell Tumors: A Clinical and Radiographic Review of Solitary vs. Bifocal Tumors and Its Therapeutic Implications.

Cancers (Basel) 2020 Sep 14;12(9). Epub 2020 Sep 14.

Division of Pediatric Neurosurgery, Ann & Robert H. Lurie Children's Hospital, Chicago, IL 60611, USA.

Suprasellar germ cell tumors (S-GCTs) are rare, presenting in either solitary or multifocal fashion. In this study, we retrospectively examine 22 solitary S-GCTs and 20 bifocal germ cell tumors (GCTs) over a 30-year period and demonstrate clinical, radiographic, and prognostic differences between the two groups with therapeutic implications. Compared to S-GCTs, bifocal tumors were almost exclusively male, exhibited higher rate of metastasis, and had worse rates of progression free and overall survival trending toward significance.

Neuropathology 2021 Feb 9;41(1):37-41. Epub 2020 Sep 9.

Department of Pathology, The First Affiliated Hospital of USTC, University of Science and Technology of China, Hefei, China.

Desmoplastic myxoid tumor (DMT), SMARCB1 mutant is a recently proposed new entity that mainly occurs in the pineal region and has epigenetic features similar to those of atypical teratoid/rhabdoid tumors (AT/RT)-MYC and poorly differentiated chordomas. Herein, we present a new case of a 33-year-old man with headaches, dizziness, nausea, vomiting, and blurred vision, who was initially found to have a suspicious germinoma on imaging. After surgical removal of the lesion, the postoperative pathological diagnosis was DMT, SMARCB1 mutant. Read More

Neuroendocrinology 2020 4;110(5):422-429. Epub 2019 Jul 4.

Department of Endocrinology, Post Graduate Institute of Medical Education and Research, Chandigarh, India,

Germinomas are highly immunogenic tumors eliciting a strong peri-tumoral immune response that can spillover into the surrounding healthy tissues. This phenomenon can also occur in intracranial germinomas, manifesting as secondary hypophysitis. Herein, we report a case of 12-year-old-girl presenting with polyuria and polydispsia. Read More
