An atypical case of focal nodular hyperplasia. Problems of imagistic diagnosis

Abstract

Focal nodular hyperplasia (FNH) is a hepatic disease first described in 1958. The existence of an accessible and minimally invasive imagistic investigation to establish the diagnosis in a large number of cases would be desirable, especially because once diagnosed, the disease needs no treatment. We present the case of a young woman with long term use of oral contraceptives in which the diagnosis of FNH was established at a routine ultrasound. Evolution of disease during the pregnancy and the atypical imagistic aspect of liver lesions raised many problems of differential diagnosis.

Focal nodular hyperplasia that mimicked a liver metastasis from a soft tissue sarcoma: a case report

“…However, several clinical cases have been surgically resected due to inaccurate diagnosis [7–9], mainly because differential diagnosis of FNH includes many kinds of hypervascular hepatic tumors. When a patient has other malignant disease, diagnosis of FNH can be even more complicated.…”
