ABSTRACT

Herpes zoster, caused by the reactivation of the varicella-zoster virus, predominantly affects individuals over the age of 65 and those with compromised immune systems. It may result in both sensory and motor neurological complications. Approximately 95% of postherpetic complications are sensory, whereas motor neuropathy involving abdominal muscles is rarely reported, affecting only 0.17% of cases. We present a case of a 74-year-old male diagnosed with postherpetic right abdominal pseudohernia, due to affection of the motor fibers of the spinal nerves. The dermatological examination revealed a characteristic vesicular rash in the Th 9-11 dermatomal distribution, along with a visible abdominal bulge on the right abdominal flank. The coexistence of myasthenia gravis may have predisposed VZV reactivation. It is essential to distinguish this condition from more common causes such as true abdominal hernias that often require surgical intervention. Continued follow-up is crucial to ensure complete resolution and prevent long-term complications.
