Foreign body granuloma mimicking liver metastasis

Abstract

In this study, foreign body granuloma mimicking liver metastasis diagnosed on routine follow-up examination in a 41-year-old woman with rectal adenocarcinoma is reported. To our knowledge, this is the first study in English-language literature reporting foreign body granuloma indistinguishable from liver metastasis on radiological examination.

Foreign Body Granulomas Simulating Recurrent Tumors in Patients Following Colorectal Surgery for Carcinoma: a Report of Two Cases

“…Foreign body materials that can induce a foreign body reaction include non-absorbable suture materials, surgical sponges, Teflon and activated charcoal (4-8). These lesions are of clinical importance because they create imaging findings that may be confused with a malignant lesion, which can lead to unnecessary surgical treatment.…”

“…Imaging appearances of foreign body granulomas that have previously been reported in the clinical literature are frequently described as peripheral enhancing masses on contrast-enhanced CT scans or MR images and ring-shaped FDG uptakes on PET/CT scans (4, 8-11). These appearances represent the wall formation induced by a fibroblastic reaction.…”

A foreign body in liver mimicking an intrahepatic cholangiocarcinoma

“…But CECT of our patient showed a prominent liver lesion similar to an intrahepatic cholangiocarcinoma, with misleadingly prominent paraaortic lymph nodes. An unknown foreign body mimicking colorectal liver metastases has been reported [4]. According to two previous case reports, a foreign body could simulate carcinoma in the head of pancreas [5,6].…”

Imaging Diagnosis—ultrasound Uncommon Features of an Abdominal Gossypiboma in a Dog

“…To confuse a textiloma with a tumor is not an exceptional situation, particularly with other imaging modalities. Advantageously, the presence of a pure distal acoustic shadow, as systematically reported in the ultrasound literature, strongly supports the diagnosis of textiloma.…”
