We report here two cases of foreign body granulomas that arose from the pelvic wall and liver, respectively, and simulated recurrent colorectal carcinomas in patients with a history of surgery. On contrast-enhanced CT and MR images, a pelvic wall mass appeared as a well-enhancing mass that had invaded the distal ureter, resulting in the development of hydronephrosis. In addition, a liver mass had a hypointense rim that corresponded to the fibrous wall on a T2-weighted MR image, and showed persistent peripheral enhancement that corresponded to the granulation tissues and fibrous wall on dynamic MR images. These lesions also displayed very intense homogeneous FDG uptake on PET/CT.

OBJECTIVETo explore the feasibility of CT guided percutaneous incisional needle biopsy (PINB) for deep pelvic masses at different locations via various puncture approaches.
METHODSPINBs under CT guidance were performed in 70 patients with 72 pelvic lesions through different puncture approaches. Their pathological findings and safety were evaluated after follow-up of a period of 1-34 months.
RESULTSPINBs were performed through transpiriform-muscle in 27 cases, 16 through transgluteal approach, 5 through posterior oblique approach in prone position, 8 by anterior or lateral transabdominal route, 8 through iliopsoas muscle and 8 by direct transosseous approach, respectively. Sixty-four malignant lesions were confirmed by pathology, including 30 adenocarcinomas, 19 squamous cell carcinomas, 5 unclassified malignant tumors, 3 small cell carcinomas, 2 malignant giant cell tumors of bone, 2 hepatocellular carcinomas and 3 false negative lesions which were confirmed at the second PINBs as malignant tumors, respectively. Benign neoplasms were confirmed in 8 cases, including fibrosis tissue in 6 lesions, bone tuberculosis in 1 and ovarian cyst in 1. The sensitivity, specificity, and accuracy rate were 95.3% (61/64), 100% (8/8), and 95.8% (69/72), respectively. Twenty-two cases via transpiriform-muscle approach suffered from transient deep pelvic pain which radiated to the lower limbs of the same side. No hematoma, nerve damage, infection, and tumor transplantation in pelvic cavity developed after the PINB procedure.
CONCLUSIONCT guided percutaneous incisional needle biopsy through different puncture approaches is safe and feasible for the patients with deep masses at different locations in the pelvic cavity.

Reports of metastatic hepatocellular carcinoma (HCC) without a primary liver tumor are rare. Here we present a case of isolated HCC that had metastasized to the pelvic bone without a primary focus. A 73-year-old man presented with severe back and right-leg pain. Radiological examinations, including computed tomography (CT) and magnetic resonance imaging (MRI), revealed a huge mass on the pelvic bone (13x10 cm). He underwent an incisional biopsy, and the results of the subsequent histological examination were consistent with metastatic hepatocellular carcinoma. The tumor cells were positive for cytokeratin (AE1/AE3), hepatocyte paraffin 1, and glypican-3, and negative for CD56, chromogranin A, and synaptophysin on immunohistochemical staining. Examination of the liver by CT, MRI, positron-emission tomography scan, and angiography produced no evidence of a primary tumor. Radiotherapy and transarterial chemoembolization were performed on the pelvic bone, followed by systemic chemotherapy. These combination treatments resulted in tumor regression with necrotic changes. However, multiple lung metastases developed 1 year after the treatment, and the patient was treated with additional systemic chemotherapy.

The occurrence of hepatocellular carcinoma (HCC) is closely associated with viral hepatitis or alcoholic hepatitis. Although active surveillance is ongoing in Korea, advanced or metastatic HCC is found at initial presentation in many patients. Metastatic HCC presents with a hypervascular intrahepatic tumor and extrahepatic lesions such as lung or lymph node metastases. Cases of HCC presenting as carcinoma of unknown primary have been rarely reported. The authors experienced a case of metastatic HCC in a patient who presented with a metastatic bone lesion but no primary intrahepatic tumor. This case suggests that HCC should be considered as a differential diagnosis when evaluating the primary origin of metastatic carcinoma.
