BACKGROUNDDuring scanning of the right hypochondrium and right intercostal regions with an ultrasonic transducer, several ultrasonic images of oblique sections are obtained. It is still a challenge for ultrasonography to divide these non-conventional sections into an accurate hepatic segmentation pattern. The aim of this research was to investigate the value of the virtual hepatic segment model (VHSM) in assisting the ultrasonic localization of space-occupying hepatic lesions.
METHODSVHSM was constructed via 3D reconstruction according to the first Chinese visible human dataset. Preoperative ultrasonography, contrast-enhanced CT scan and VHSM techniques were performed in 100 patients with space-occupying focal lesions in the liver parenchyma for segmental localization. The results of these three techniques were compared with the operative findings.
RESULTSVHSM was successfully detected on 2D sectional images by 3D reconstruction through surface rendering and volume rendering. The model could simulate ultrasonic directions to conduct a virtual dissection on any section plane, and fine liver segmentation could be displayed in any virtual plane. In 100 patients, there were 112 liver space-occupying focal lesions distributed in 148 liver segmentations. Regarding the positioning accuracies for lesions of different sizes and the lesion segmental distribution accuracies estimated using the three methods mentioned above, ultrasonography exhibited a significantly lower accuracy than VHSM for the segmental localization of lesions (P < 0.05), and contrast-enhanced CT was not significantly different from ultrasonography plus VHSM (P > 0.05).
CONCLUSIONVHSM increased the accuracy of ultrasonic localization of space-occupying hepatic lesions, particularly in hepatic hypovascular regions.

Focal nodular hyperplasia (FNH) is the second most common benign solid tumor of the liver and is usually found in young females. In FNH, spontaneous bleeding or rupture rarely occurs and malignant transformation is unlikely. The etiology of FNH is unclear, but because of female predominance and young age at onset, it seems that female hormone has an important role for the development of FNH. Although the development and the complications of hepatocellular adenomas have been related to the use of oral contraceptives and pregnancy, the influence of oral contraceptives and pregnancy on the growth and complications of FNH is controversial. Most FNH are stable in size and rarely complicated during pregnancy. We describe here a case of FNH with growth progression during pregnancy in a 27-year-old female. Her course of pregnancy and delivery was uneventful. Two months after delivery, the size of FNH was decreased.

We report herein a case of hepatoid adenocarcinoma of the stomach with liver metastasis. Gastric carcinoma generally presents as adenocarcinoma and rarely shows a hepatoid pattern, which can produce alpha-fetoprotein (AFP). The stomach is one of the common sites at which hepatoid adenocarcinoma has been detected. A 75-year-old female patient was admitted to the hospital with a symptom of epigastric discomfort. Gastrofibroscopy revealed a large tumor occupying the greater curvature of the stomach body. The level of serum AFP was markedly increased. Abdominal computed tomography revealed multiple liver masses. Biopsy samples of the gastric lesion and liver masses finally confirmed her case as hepatoid adenocarcinoma in the stomach with liver metastasis. The AFP-producing gastric carcinoma needs special attention because it often presents with early liver metastasis and has a poor prognosis.
