Neuro Exam Practice Test 2025 – Complete Preparation Guide

The investigation of choice for a toddler presenting with status epilepticus is a CT scan of the head. This imaging modality is typically used in acute settings to quickly identify any structural causes of seizures, such as hemorrhages, tumors, or acute traumatic injuries that may not be immediately apparent through a physical examination alone.

In cases of status epilepticus, especially in the pediatric population, it is crucial to rule out any emergent intracranial pathologies. A CT scan can be performed rapidly and effectively in an emergency department setting, making it the most suitable initial imaging choice to evaluate for potential causes of the seizure activity.

Other modalities such as MRI or EEG may have their respective uses, but they are not the first-line investigations in the context of an emergency presentation. MRI is more time-consuming and may not be readily available in urgent situations. EEG is important for diagnosing seizure types and patterns but does not provide immediate information regarding structural abnormalities. An ultrasound of the brain is not typically used in this context for older toddlers and would not adequately assess the underlying issues related to status epilepticus.
