Abstract
When Magnetic Resonance Imaging Cannot be Missed for Evaluation of Pediatric Seizures
Highlights
Seizure is a common presenting symptom of pediatric brain tumors, but brain tumor remains a rare cause of epilepsy in childhood [3]
We present three cases of brain tumors presenting with seizures and diagnosed with Magnetic resonance imaging (MRI)
The MRI revealed a cortical mass in the right frontal operculum likely to be Glioma or Dysembryplastic Neuroepithelial Tumor (DNET) with associated focal cortical dysplasia (Figure 1)
Summary
Brain tumors (BT) account for nearly 25% of all cancers in children and have the highest mortality rate of all pediatric malignancies [1,2]. A 12 y/o female presented an episode of loss of movement of her left hand, associated with asymmetry and twitching of Figure 2: MRI without contrast shows a 1.1 x 0.8 x 0.7cm mass within the left temporal lobe, hypointense on T1 (left) and T2 (right) with surrounding vasogenic edema. The availability of high-quality MRI allows for an in vivo view of pathological anatomy as well as detection of lesions such as migration defects and mesial temporal sclerosis, both of which are known causes of childhood onset seizure. These two abnormalities are not readily seen on computed tomography (CT). On the follow up visit, he rejected the surgical approach and elected to follow the lesion
