Focal nodular hyperplasia of the liver: a report of 60 cases / 中国普通外科杂志

ABSTRACT

Objective To evaluate the diagnosis and treatment of focal nodular!hyperplasia of the liver (FNH). Methods Retrospective analysis was made on 60 FNH cases in terms of clinical findings, images, pathologic examination and surgical treatment. Results Of the 60 FNH patients in our hospital from 1993 to 2003, 41 were male and 19 female. The average age was 37 year′s old. Fifty-five cases had single focus, the other five were of multiple lesion, with tumor diameter 10cm in one. Correct preoperative diagnosis was made in 33 cases (55%). The correct diagnostic rate of BUS, CT and MRI was 33.3%, 58.3% and 72.0%, respectively. All 60 cases underwent operation with an uneventful recovery and without recurrence at follow-up. ConclusionsCT and MRI are mandatory for the diagnosis of FNH. Definite preoperative diagnosis is usually difficult even in cases of typical type of FNH. Surgical resection is the treatment of choice when a patient becomes symptomatic or when malignancy could not be excluded.
