Spontaneous Arachnoid Cyst Rupture with Subdural Hygroma in a Child.

Area of Science:

• Pediatric Neurosurgery
• Neurology
• Radiology

Background:

• Arachnoid cysts of the brain are common in children.
• Association with spontaneous subdural hygroma is rare.
• Presents a unique case in a pediatric patient without trauma history.

Purpose of the Study:

• To report a rare case of pediatric arachnoid cyst with subdural hygroma.
• To describe the clinical presentation, diagnostic findings, and management.
• To emphasize the importance of considering rare associations in pediatric neurosurgery.

Main Methods:

• Case presentation of a nine-year-old boy with neurological symptoms.
• Diagnostic imaging using Magnetic Resonance Imaging (MRI).
• Surgical management including craniectomy and burr hole drainage.

Main Results:

• MRI revealed a large left temporal arachnoid cyst and bilateral frontoparietal subdural hygromas.
• Surgical drainage of the cyst and hygromas was performed.
• Histopathology confirmed arachnoid cyst with subdural cerebrospinal fluid collection.

Conclusions:

• This case highlights a rare association between brain arachnoid cysts and subdural hygromas in children.
• Prompt diagnosis and surgical intervention are crucial for favorable outcomes.
• Further research may elucidate the underlying pathophysiology of this rare condition.
