We report the case of a 27-year-old survivor of the Halloween crowd crush in Itaewon, Seoul, Korea who was diagnosed with left sciatic neuropathy and right common peroneal neuropathy accompanied by multifocal rhabdomyolysis. The patient presented to the emergency room complaining of pain from her lower back to her whole lower extremities with paraparesis and paresthesia. Her blood test showed the marked elevation of creatine kinase and liver enzymes. Magnetic resonance imaging revealed multifocal signal changes in the abdominalis and pelvic girdle muscles suggestive of rhabdomyolysis. Magnetic resonance neurography demonstrated injury to the left sciatic and right peroneal nerves.Electrophysiologic studies also revealed lesions in the left sciatic and right peroneal nerves. After comprehensive rehabilitation and conservative treatment for three months, her muscle strength improved, and she could walk independently. Although several previous studies have reported peripheral neuropathy in immobilized patients, to the best of our knowledge, no case associated with a crowd crush has been reported. Therefore, we report the case of multifocal neuropathy combined with rhabdomyolysis in a victim of a crowd crush incident with good recovery.

Coronavirus disease 2019 (COVID-19) has been associated with various neurological complications, including the rare occurrence of spinal cord infarction. In this report, we present the case of a 42-year-old man who developed sudden quadriplegia after being diagnosed with COVID-19. Initial magnetic resonance imaging (MRI) provided inconclusive results; however, subsequent imaging revealed diffusion restriction and vertebral body signal changes, indicative of ischemic changes in the spinal cord. The patient received anticoagulation and corticosteroid therapy followed by rehabilitation, resulting in partial recovery of motor function. This case illustrates the importance of considering spinal cord infarction in patients with COVID-19 who present with neurological symptoms. Furthermore, it highlights the crucial role of MRI, including diffusion-weighted imaging, in diagnosis.
