Angiomyxomas are uncommon myxoid tumours arising most commonly from the pelvis. A 46-year-old woman with a history of polycystic kidney disease presented asymptomatically for surveillance ultrasonography; changes were noted in the size and morphology of her liver cysts. Subsequent radiological assessment displayed features suspicious of malignancy and a right hemihepatectomy was performed with curative intent. Pathological examination of the resected specimen found histology consistent with an angiomyxoma arising primarily from the liver parenchyma. Follow-up review of the patient has been uneventful with annual imaging showing no evidence of recurrence. Angiomyxomas do not characteristically invade other tissues. However, any liver lesion displaying suspicious features of malignancy should be resected in the absence of disseminated disease.
