Abstract:
An old woman with abdominal pain complained a palpable mass on the right anterior abdominal wall. On PET/CT images, the lesion presented as a soft tissue mass with irregular shape, invading adjacent peritoneum and showing intense FDG uptake. Based on imaging findings, a malignancy was suspected, and she underwent surgical resection. However, the abdominal wall mass was diagnosed as granulomatous inflammation with a little necrosis by pathological results. Awareness of this benign disease is helpful for an accurate diagnosis of abdominal wall mass.
