In patients with liver cirrhosis, arterial phase enhancement of nodular lesions on helical-CT is currently considered to be highly predictive of malignancy. We report the spontaneous regression of a hypervascular hepatic nodule in a patient with liver cirrhosis within 7 months demonstrated by helical-CT follow-up. This suggests that tumour angiogenesis known to be an obligatory step for acquisition of malignant properties could regress, and can be demonstrated by helical CT. Radiologists should be aware that CT detection of a hypervascular nodule in a cirrhotic liver is not always predictive of a malignant outcome.
Case Details
Disease Location
Liver
Personal Characteristics
77-year-old with 10 year history of HBV infection and liver cirrhosis
Clinical Characteristics
Us showed the presence of a hypoechoic lesion of the right liver lobe. CT displayed a 3mm diameter low attenuation of the right liver lobe.
Remission Characteristics
A second abdominal CT scan was thus performed 7 months later no hypervascular nodule could be detected. A 5-mm non-enhancing lesion was present at the location of the initial nodule. After 30- months follow-up the patient is well and recent us examinations have been unable to detect initial liver lesion recurrence.
