Figure 13. Foreign-body granuloma in a 39-year-old woman with a palpable mass for 10 years and abdominal pain for 1 week. Unenhanced CT scan shows a large, well-circumscribed mass with dense calcification in the anterior midabdomen, an appearance suggestive of a foreign-body granuloma or organizing hematoma. After injection of contrast material, the mass showed no enhancement. A foreign-body granuloma with surgical gauze was found at surgical excision. The patient had a history of cesarean section 10 years earlier.
