[A toddler with vomiting and abnormal eye movements].

Area of Science:

• Pediatric Neurology
• Neuroradiology
• Neuroscience

Background:

• Subdural hematomas (SDHs) are collections of blood between the dura mater and arachnoid mater.
• Arachnoid cysts are congenital abnormalities resulting from a separation of the arachnoid mater layers.
• Both conditions can present with non-specific neurological symptoms in pediatric patients.

Observation:

• A 1.5-year-old female child presented with acute onset of vomiting.
• The patient subsequently developed abnormal eye movements, indicative of neurological compromise.
• Initial clinical presentation raised concerns for intracranial pathology.

Findings:

• Magnetic Resonance Imaging (MRI) of the brain revealed a significant subdural hematoma.
• The MRI also identified an associated arachnoid cyst.
• The co-occurrence of SDH and arachnoid cyst in this pediatric case is noteworthy.

Implications:

• This case underscores the necessity of advanced neuroimaging, such as MRI, for diagnosing complex intracranial pathologies in children.
• Understanding the relationship between subdural hematomas and arachnoid cysts is crucial for appropriate management and prognosis.
• Further research may elucidate the pathophysiological mechanisms linking these two conditions in pediatric populations.
