Abstract

PURPOSE: To determine the need for follow-up imaging in patients with a low risk of malignancy and with ultrasonographic (US) findings typical of hepatic hemangioma. MATERIALS AND METHODS: A computer search of US reports completed between 1991 and 1994 helped identify 383 patients whose reports contained the word "hemangioma. " One hundred eleven patients were excluded because the lesion's appearance was atypical (n = 16) or because the patients' had a high riskof malignancy (prior history or current evidence of extrahepatic malignancy or chronic hepatic disease [n = 95]). Fifty-nine patients were excluded because they were lost to follow-up (n = 41) or had clinical follow-up of less than 2 years (n = 18). The conditions of the remaining 213 patients withtypical-appearing hemangiomas and a low risk of malignancy were analyzed. One hundred twenty-one patients underwent imaging follow-up or histopathologic confirmation. Ninety-two had clinical follow-up of more than 2 years (mean, 46 months). RESULTS: Of the 213 patients, four had benign lesions other than hemangiomas. One patient who subsequently developed a malignancy (neuroendocrine metastases from primary colonic carcinoma diagnosed 22 months after initial US) potentially had an early metastasis ti;at was misdiagnosed as a hemangioma. CONCLUSION: On the basis of these results, the authors no longer recommendfollow-up studies in their patients with a low risk of malignancy and a typical-appearing hemangioma at US.
