In recent years, with the widespread use of assisted reproductive technologies, questions have arisen regarding the possible relationship between these infertile parents with assisted conception procedures and childhood cancers. We present a 23-day-old newborn conceived by in vitro fertilization (IVF) with a 53 × 46 × 38 mm intracranial mass detected by magnetic resonance imaging on the 15th postnatal day. The mass, removed on 23rd postnatal day, was an Atypical Teratoid Rhabdoid Tumor (ATRT), WHO grade 4. As far as we know, this is the only neonatally detected ATRT. Further studies are needed to investigate whether there is a causal relationship between IVF and childhood cancers.

Pediatric skull base tumors: Clinical features and surgical outcomes; a single center retrospective study with a review of literature.
Brain Spine
November 2024
Department of Neurosurgery, Heidelberg University Hospital, Heidelberg, Germany.
Article Synopsis
- Pediatric intracranial tumors at the skull base are rare, challenging to treat due to complex anatomy, and lack substantial clinical evidence, prompting a study on surgical approaches and outcomes.
- The study involved 12 children under 18 who underwent skull base surgery from 2017 to 2023, analyzing demographics, tumor details, surgical methods, and survival rates.
- Results indicated a predominance of female patients, varying tumor locations and types, with 58.3% achieving gross or near-total resection; however, 33.3% of patients died from tumor progression within an average of 15 months.
Atypical teratoid/rhabdoid tumors (AT/RTs) of the central nervous system (CNS) are rare and aggressive, typically occurring in early childhood or infancy, with adult cases being extremely rare. These tumors are associated with the inactivation of the integrase interactor 1 (INI1) gene. The prognosis is poor, worsening significantly if metastasis is detected at diagnosis.

Background: Inhibitors targeting cyclin-dependent kinases 4 and 6 (CDK4/6), crucial for cell cycle regulation, have shown promise in early-stage studies for treating central nervous system (CNS) tumors. However, challenges such as limited CNS penetration, optimal treatment duration, and systemic side effects have impeded their clinical translation for pediatric brain tumors (PBTs).
Methods: We evaluated the potency of CDK4/6 inhibitors across various PBTs cell lines, focusing particularly on palbociclib against atypical teratoid rhabdoid tumor (ATRT) with cell viability assays and gene expression analysis.
A rare case of atypical teratoid rhabdoid tumor at the sellar region in an adult: Case report and review of literature.
Brain Spine
November 2024
Department of Neurosurgery, General Hospital of Nikaia 'Agios Panteleimon', 18454, Athens, Greece.
Article Synopsis
- Atypical teratoid/rhabdoid tumor (AT/RT) is a rare brain cancer mainly found in children, but can appear in adults, especially in the sellar region of middle-aged women.
- A case study is presented of a 51-year-old woman with AT/RT who had headaches and left ptosis, leading to a diagnosis and treatment that included surgery, radiation, and chemotherapy.
- Despite treatment, the patient developed lung metastases and passed away seven months post-diagnosis, highlighting the need for further awareness of AT/RT in adults, particularly when considering sellar masses.
