Abstract
We report three cases of abdominal postherpetic neuralgia (PHN) complicated by motor paresis. Case 1: A 76-year-old man with severe pain in his right abdomen owing to herpes zoster (HZ) was admitted to our hospital 28 days after symptoms began. Case 2: A 75-year-old woman with severe pain in her right lower abdomen owing to HZ was admitted to our hospital 29 days after symptoms began. Case 3: A 72-year-old man with severe pain in his right abdomen also owing to HZ was admitted to our hospital 80 days after symptoms began. All three cases were diagnosed as abdominal PHN complicated by motor paresis attributable to bulging in one side flank and thinning of abdominal muscle as revealed by ultrasound imaging. Although a diagnosis of limb paresis is typically easy, abdominal paresis is difficult to detect.
