Common Pediatric Brain Tumors and Their Imaging Features
Finding and diagnosing pediatric brain tumors relies a lot on imaging. It’s key to know how common tumors like medulloblastomas, gliomas, and ependymomas look on scans. Each type of tumor has its own look, helping doctors make the right diagnosis and plan treatment.
Medulloblastoma
Medulloblastomas are common and dangerous brain tumors in kids. They usually show up as a mass in the middle of the cerebellum on scans. These tumors sit in the back of the brain and can push on the fourth ventricle, causing fluid buildup.
On MRI, they can look different because of dead spots, bleeding, and cysts. They often light up on contrast scans, which helps tell them apart from other brain tumors in kids.
Gliomas
Pediatric Brain Tumor Radiology Essentials Gliomas are a group of brain tumors that can look and behave differently. In kids, they can be spread out and show up in many ways on MRI. The low-grade ones might be well-defined and not show up on contrast scans. But the high-grade ones can have rough edges, ring-like enhancement, and swelling around them.
Using advanced scans can help tell these tumors apart and plan treatment.
Ependymoma
Ependymomas are found in the ventricles or spinal cord. They look different on MRI, showing up as mixed signals on T1 and T2 scans. These tumors can make the ventricle bigger and might show up brighter after contrast.
Knowing these signs is key to telling them apart from other brain tumors in kids.
Here’s a table to help understand the MRI signs of these tumors:
| Tumor Type | Location | MRI Characteristics |
|---|---|---|
| Medulloblastoma | Midline Cerebellar | Heterogeneous signal, contrast enhancement, posterior fossa |
| Glioma | Varies (e.g., supratentorial, brainstem) | Infiltrative lesions, variable intensity, ring enhancement (high-grade) |
| Ependymoma | Ventricles, spinal canal | Heterogeneous signal, ventricle expansion, variable enhancement |
Imaging Techniques Used in Pediatric Brain Tumor Diagnostics
Pediatric brain tumor diagnostics use advanced imaging to see the brain’s soft tissues. MRI and CT scans are key tools. They help doctors make good treatment plans.
