We report clinical details and imaging findings of a case of a giant pseudocyst occurring in the anterior abdominal wall of a 61-year-old female. This was a late complication following the repair of an incisional hernia with mesh. Surgical excision revealed a well-encapsulated pseudocyst with histopathology confirming absence of epithelial cells. We further discuss current treatment methods for incisional hernias, as well as prevalence, etiology, and management of pseudocysts complicating hernioplasty.
