["Sacroiliitis" as the initial manifestation of hepatocarcinoma].

The hepatocellular carcinomas rarely develop in absence of a previous hepatopathy and their first clinical manifestations are not related, in general, to the metastasis located at the bones of the pelvic girdle. We present a multifocal hepatocarcinoma in a 17-year-old woman without known risk factors, whose initial manifestation was a clinical radiological picture suggesting left sacroiliitis. We stress this rare manifestation preceding the diagnosis of neoplasia two years later.
