Segmental zoster paresis is characterized by focal motor weakness affecting the myotome corresponding to the dermatomal distribution of the rash. Clinically, it presents as pseudohernia when it involves abdominal wall muscles. We report three cases of segmental zoster paresis presenting as pseudohernia of abdominal wall. All patients developed asymptomatic bulge in anterolateral side of abdomen between 10 and 15 days after appearance of vesicles. All patients developed post-herpetic neuralgia. One patient developed pseudo-obstruction of colon due to visceral involvement. Segmental zoster paresis of lower thoracic spinal segment often goes unnoticed due to its asymptomatic nature.
