Summary
Prenatal diagnosis of congenital brain tumors, like primitive neuroectodermal tumors (PNETs), is crucial. Early detection impacts delivery and postnatal care planning for these rare fetal and neonatal brain tumors.
Area of Science:
- Pediatric oncology
- Neuro-oncology
- Fetal medicine
Background:
- Congenital brain tumors are rare, diagnosed in the first year of life, accounting for 1.4-8.5% of childhood brain tumors.
- Only 18% of these tumors are detected prenatally, highlighting a gap in early diagnosis.
- Primitive neuroectodermal tumors (PNETs) are highly malignant congenital brain tumors, comprising 13% of fetal and neonatal cases, with high mortality rates.
Observation:
- A case of a prenatal primitive neuroectodermal tumor (PNET) was identified.
- Diagnostic imaging modalities included ultrasonography and magnetic resonance imaging.
- Histopathological examination postmortem confirmed the PNET diagnosis.
Findings:
- Prenatal diagnosis of congenital brain tumors, including PNETs, is feasible using advanced imaging techniques.
- The study presents a confirmed case of a prenatal PNET diagnosed via ultrasonography and MRI.
- Postmortem histopathology verified the diagnosis, underscoring the accuracy of prenatal imaging.
Implications:
- Prenatal diagnosis of congenital brain tumors can significantly influence delivery timing and mode.
- Early detection allows for optimized postnatal care planning for affected neonates.
- Improved prenatal detection strategies for PNETs and other congenital brain tumors are essential for better outcomes.

01:20The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

01:30Neurulation
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
