a limited protrusion of the abdominal wall, without structural defect

Causes include:

  • diabetic radiculoneuropathy,
  • Lyme disease,
  • polymyositis,

Classically, reactivation herpes zoster infection affects sensory nerve roots

however, it may extend to motor involvement, which can include paresis of diaphragmatic, upper and lower limb, or abdominal musculature.


Natural History:pseudohernia1

Symptoms of abdominal wall pseudohernia typically occur within 2 weeks of the rash and typically include an abdominal bulge in the region of the affected dermatome.

Typically, patients have a good prognosis, with resolution of symptoms within 18 months
