Abstract:
Transforaminal epidural steroid injections have been introduced as a nonsurgical treatment for cervical pain syndromes; however, they have also raised safety concerns. We present a patient who developed a headache and bilateral visual disturbance after cervical transforaminal epidural steroid injections. Brain magnetic resonance imaging showed a high signal intensity in the posterior region on T2-weighted and fluid-attenuated inversion recovery images, and the findings of diffusion-weighted imaging and the apparent diffusion coefficient map suggested vasogenic edema. The symptoms and abnormal imaging findings disappeared during follow-up. The clinical and imaging characteristics and their complete reversibility corresponded to reversible posterior leukoencephalopathy syndrome.
