Insights
Pediatric supratentorial embryonal tumors with multilayered rosettes (ETMR) typically present as large cystic and solid masses with calcifications. Recognizing these imaging features aids in the accurate diagnosis of ETMR in children.
Area of Science:
- Pediatric Neuroradiology
- Neuro-oncology
- Oncopathology
Context:
- Embryonal tumors with multilayered rosettes (ETMR) are rare, aggressive brain tumors predominantly affecting young children.
- Accurate diagnosis of pediatric brain tumors is crucial for timely and appropriate treatment planning.
Purpose:
- To analyze and summarize the characteristic imaging findings of pediatric supratentorial ETMR.
- To correlate imaging features with clinical data for improved diagnostic accuracy.
Summary:
- Seven cases of pediatric supratentorial ETMR (four males, three females; ages 2-6 years) were analyzed.
- Typical imaging findings include large cystic and solid masses, calcification, significant mass effect, and mild peritumoral edema.
- The solid components often exhibit heterogeneous, mild enhancement, aiding in differentiation.
Impact:
- Highlights the value of specific imaging manifestations in the diagnosis of supratentorial ETMR.
- Contributes to the understanding of rare pediatric brain tumors, potentially improving diagnostic workflows.
Abstract:
We analyzed and summarized the imaging characteristics and clinical data of seven pediatric supratentorial embryonal tumors with multilayered rosettes (ETMR). There were four boys and three girls aged from two to six years old. Pediatric supratentorial ETMR often presented large cystic and solid mass, calcification, significant mass effect and mild peritumoral edema. The solid part often showed heterogeneous mild enhancement. In combination with the location of tumor and age of onset, the typical imaging manifestations of supratentorial ETMR in children are valuable for accurate diagnosis.
