Purpose:
To describe the natural history of liver adenomatosis (LA), including complications and changes in lesion size over time.
Materials And Methods:
Eighteen patients with clinical diagnosis of LA were included. Clinical and biochemical information were collected. The initial and follow-up MR studies were reviewed retrospectively to determine change in lesion size and imaging features.
Results:
Seventeen patients were women (94.4%). The mean age of the initial MR study was 37.0 years (18-52 years). The median size of the largest lesion was 6.7 cm (range 3.0-13.5 cm). Intratumoral bleeding was detected on MRI in 9 lesions, in 7 patients (38.8%). The median size for hemorrhagic lesions was 7.6 cm (range 4.1-13.5 cm). During the mean follow-up period of 29.4 (range 4-98) months, 10 patients had stable disease (55.6%), and 8 patients had tumor regression (44.4%). Of 8 patients who were followed without intervention, 3 patients (37.5%) had spontaneous regression. No malignant transformation or lesion progression was occurred.
Conclusion:
During an over 2-year follow-up period, the majority of lesions of LA appeared to remain stable or showed tumor regression. Spontaneous tumor regression can be observed in approximately 37% of individuals in the age range of 28-53 years.
