Elevated Intracranial Pressure Diagnosis with Emergency Department Bedside Ocular Ultrasound

الملخص EN

Bedside sonographic measurement of optic nerve sheath diameter can aid in the diagnosis of elevated intracranial pressure in the emergency department.

This case report describes a 21-year-old female presenting with 4 months of mild headache and 2 weeks of recurrent, transient binocular vision loss.

Though limited by patient discomfort, fundoscopic examination suggested the presence of blurred optic disc margins.

Bedside ocular ultrasound (BOUS) revealed wide optic nerve sheath diameters and bulging optic discs bilaterally.

Lumbar puncture demonstrated a cerebrospinal fluid (CSF) opening pressure of 54 cm H2O supporting the suspected diagnosis of idiopathic intracranial hypertension.

Accurate fundoscopy can be vital to the appropriate diagnosis and treatment of patients with suspected elevated intracranial pressure, but it is often technically difficult or poorly tolerated by the photophobic patient.

BOUS is a quick and easily learned tool to supplement the emergency physician’s fundoscopic examination and help identify patients with elevated intracranial pressure.
