Hepatocellular carcinoma, CT

Yan Hu, Yalan Liu, Hongcheng Shi
RATIONALE: Castleman disease is a rare lymphoproliferative disorder which etiology is unknown. It is divided into 2 subtypes: the plasma cell variant and the hyaline vascular variant. The most common site is the hilum of the lungs and mediastinum. Castleman disease is often ignored by clinicians because of not frequently encountering in clinical and the lower uptake of F-FDG. Here, we report a case of hepatocellular carcinoma accompanied by Castleman disease in the hilum of the liver, which was misdiagnosed as the lymph node metastasis in F-FDG PET/CT imaging...

Hepatocellular carcinoma (HCC) usually develops in the setting of chronic liver disease. In the adequate clinical context, both multiphasic contrast-enhanced CT and magnetic resonance imaging are non-invasive modalities that allow accurate diagnosis and staging of HCC, although the latter demonstrates greater sensitivity and specificity. Imaging criteria for HCC diagnosis rely on hemodynamic features such as hyperenhancement in the arterial phase and washout in the portal or equilibrium phase. However, imaging performance drops considerably for small (< 20 mm) nodules because their tendency to exhibit atypical enhancement patterns...

Stanniocalcin-1 (STC1) is a paracrine factor associated with inflammation and carcinogenesis. Using clinicopathological data, we previously reported that a greater expression of STC1 in hepatocellular carcinoma (HCC) was significantly correlated with smaller tumor size. The underlying mechanism on the correlation is not known. In this study, using a metastatic HCC cell-line (MHCC-97L, P) and lentiviral vector mediated-STC1 overexpression, the inoculation of STC1-overexpressing MHCC-97L (S1) cells in a nude mice xenograft model demonstrated reductions in tumor mass and volume...

Hepatocellular carcinoma with bile duct tumor thrombus (BDTT) is a malignant disease. The most commonly used diagnosis methods for BDTT are MRCP/ERCP, ultrasonic diagnosis or CT scan. However, BDTT is often misdiagnosed as other bile duct diseases, such as extrahepatic cholangiocarcinoma (EHCC), choledochal cyst (Cyst) and common bile duct stone (Stone). Diagnostic methods, which are more accurate and less destructive, are urgently needed. In this paper, we analyzed the small molecule metabolites in the serum of BDTT, Stone, Cyst and EHCC patients and normal people using untargeted GC-MS, and identified 21 metabolites that show different levels among different samples...

Hepatocellular carcinoma (HCC) is the most frequent primary hepatic cancer. Pathological features can define the biological behavior and prognosis. Medullary-like HCC is a very rare variant that has been described only twice in literature. In the present study, we report the case of a non-cirrhotic 72-year-old man, who presented two HCC lesions on routine screening for hepatitis C virus liver disease. Radiological imaging and biopsy showed two different subtypes: one classic HCC, which was treated with chemoembolization, and a second PET/CT-positive carcinoma with a PET/CT-positive metastatic coeliac lymph node, which was resected laparoscopically with a left lateral sectionectomy and extended lymphadenectomy...

A 64-year-old woman, with a history of hepatocellular carcinoma, developed recurrent metastatic lung nodules after lung metastasectomy 10 years ago. Computed tomography (CT) revealed tumors in the right middle, and left lower lobes. We planned a right middle lobectomy. Before operating, a contrast-enhanced CT in the pulmonary venous phase revealed a tumor in the pulmonary vein resembling a thrombus, indicating that the CT failed to facilitate accurate diagnosis. Following venous clamping and incision, the intravenous polypoid mass was surgically removed...
