Segmental zoster paresis (SZP) of the limbs, characterized by focal weakness of the extremity, is recognized as a rare complication of herpes zoster that can lead to a misdiagnosis of other radiculopathies or musculoskeletal problems. Here, we present a rare case where the patient experienced severe pain and weakness of the right upper extremity caused by SZP. A 58-year-old man came to the hospital with severe right upper extremity radicular pain. Cervical magnetic resonance imaging of the spinal cord showed disc protrusion at the C5-6 level with a high signal change. Anterior cervical discectomy and fusion was performed. On the first and second postoperative days, the patient’s symptoms showed slight improvements. However, on the fourth postoperative day, the patient experienced a right shoulder drop along with exacerbated radicular pain and presented a herpetic rash on the right extremity. The patient showed a dramatic improvement in pain and weakness after taking antiviral medication and undergoing a fluoroscopic-guided right C6 selective nerve root block. He fully recovered from his symptoms after 12 weeks of rehabilitation and physical therapy. This rare case involved SZP which was misunderstood as a herniated cervical disc. If a patient complains of severe pain with motor weakness inconsistent with radiologic findings, SZP should be discriminated from other possible diagnosis.
