In order to evaluate atypical aspects of hepatocellular carcinoma at computed tomography and magnetic resonance imaging, we have retrospectively evaluated 100 patients with diagnosed hepatocellular carcinoma, based on combined imaging studies, laboratory results, biopsy and surgery. We have selected those cases with atypical findings at computed tomography or magnetic resonance imaging, including cystic lesions, bleeding tumors, with calcifications, with spontaneous regression, pedunculated tumors, hypovascular lesions, giant hepatocellular carcinomas, and those with unusual local invasiveness. The hepatocellular carcinoma is the most usual primary malignant lesion of the liver and usually it has a typical aspect and is associated with hepatic cirrhosis. However, in a significant number of cases, some uncommon findings can be responsible for a delayed diagnosis.
