Abstract
Purpose: Analysis of a clinical case of detection of metastatic lesions of the mediastinal subcarinal lymph node in a patient with hepatocellular liver cancer using positron emission tomography combined with computed tomography (PET/CT).
Material and methods: A patient with moderately differentiated hepatocellular liver cancer after surgical treatment and targeted therapy revealed a biochemical relapse. Complex examination (computed tomography, magnetic resonance imaging) revealed no pathological changes. PET/CT revealed pathological accumulation of 18F-choline in the subcarinal lymph node. After performing transbronchial lymph node biopsy and histological examination metastatic lesion was confirmed.
Conclusion: Whole body PET/CT scan revealed rare metastases of hepatocellular cancer in biochemical recurrence — in the mediastinal subcarinal lymph node, in the absence of other manifestations of the disease. Whole body PET/CT is the method of choice for suspected extrahepatic localization of hepatocellular carcinoma progression.
