OBJECTIVE Our objective was to study the presence of a characteristic appearance of metastatic disease to the gastrointestinal tract on contrast-enhanced CT in patients with known malignancies and to investigate its clinical implications. CONCLUSION Twenty-five patients with scirrhous metastases had a malignant CT target sign. Careful observation and correlation with clinical history are required to differentiate this unique sign from a benign target sign.

We report the case of a 44-year-old man presenting with abdominal pain and leukocytosis. His initial computed tomography demonstrated a pancreatic head mass concerning for pancreatic adenocarcinoma. However, on further review of the patient's imaging, the mass was determined to be an abscess caused by foreign body ingestion and gastric perforation rather than cancer. This report describes the clinical and radiographic distinctions between pancreatic neoplasia and abscess. It also reviews the pertinent medical literature on how such viscus perforations affect subsequent prognostication and clinical management.
