“…Plain scan can help to locate lesions and demonstrate calcifications. Contrast scan can further demonstrate the radiological signs of its complications, define the range of alveolar Echinococcus cysts, and reveal small metastasis [2][3][4][5][6][7][8][9][10][17][18][19][20]26]. Take the hydatid cyst fluid examination during the surgerywe found a large number of protoscolex of cystic fluid from the etiological examination which is shown in Figure 4.…”

The abstract must include the following separate sections: Background: Hydatid disease, which is caused by larvae of Echinococcus multilocularis. Is common in husbandry area. It's serious disease to human that has a significantly high fatality rate. However, as a non-echinococcous endemic area, Guangxi has not reported on hydatid disease, and this first primary patient may provide new possible routes of infection and diagnostic ideas. Case presentation: A brief description of the patient's clinical and demographic details, the diagnosis, any interventions and the outcomes. The patient suffered from hypertension for 6 years and hypo tensors were used to control the blood pressure. In 2014, he was confirmed to have hepatic cyst. In December 2016, he had been hospitalized in the Department of Encephalopathy because of intracerebral haemorrhage, which led his left limb activities impaired. This patient reported a hepatic cyst detected by B-mode ultrasound during the physical examination 1 year ago. He did not pay close attention to it and did not receive any re-examination. Recently, B-mode ultrasound in another physical examination showed hepatic cyst (176 × 158 mm). No obvious abnormality was found in the gallbladder, pancreas, spleen and both kidneys. Computed tomography scan can be applied to examine all organs in human body and is an important diagnostic examination for echinococcosis. Conclusions: A brief summary of the clinical impact or potential implications of the case report. This patient finally diagnosis as Cystic echinococcosis in the right liver lobe (Simplex cyst), hypertensive disease, hemorrhage sequel and arrhythmia-atrial premature beat. According to the diagnosis, we plan the treatment as using laparoscopic surgery for echinococcosis. This case will help us to find out possible causes of the incidence of echinococcosis in Guangxi and the potential transmission risks, and thus put forward the measures for the prevention and treatment of echinococcosis in Guangxi.

“…On US, hepatic cysts appear as well-defined anechoic lesions (often multiple) with associated posterior acoustic enhancement and absent internal vascularity (Fig. 1) [13,14]. On CT, a hepatic cyst can be characterized confidently when it appears as a nonenhancing hypodense lesion with Hounsfield units measuring <20 (corresponding to fluid density) [13].…”

Liver Imaging Techniques: Recognition of Uveal Melanoma Metastases

Background: The liver is the most common site for metastases of several primary malignancies including uveal melanoma. Methods: Review of imaging characteristics of incidental common benign liver lesions including hepatic cyst, hemangioma, focal nodular hyperplasia, and hepatic adenoma and contrasting them with uveal melanoma metastases. Results: Benign hepatic lesions may be cystic or, if solid, relatively stable in size over time. For hepatic lesions larger than 10 mm in size, characteristic imaging features typically allow for confident diagnosis. When lesions are small (less than 10 mm), definitive characterization can be difficult. Moreover, lesions smaller than 10 mm can be difficult to biopsy under ultrasound or computed tomography (CT) guidance, and short-term follow-up will often be useful to assess for stability or progression. Overall, magnetic resonance imaging is more specific than CT scan and at least as sensitive as CT for detecting uveal melanoma liver metastases. Conclusions: New multiple enhancing solid liver lesions should raise suspicion of uveal melanoma liver metastases. Discussion of challenging cases with the radiologist may be beneficial, as pertinent information such as size, location, and molecular prognostication status of the primary tumor can guide radiological interpretation of hepatic lesions.

-Spaceoccupying lesions of the liver may be cystic or solid. Ultrasonography is an extremely useful method for initial screening, and suffices for diagnosis of simple hepatic cysts. Complex cysts and solid masses require computed tomography or magnetic resonance imaging for confirmation. Wide surgical excision is indicated in cystadenoma or cystadenocarcinoma. Clinical and epidemiological data are important, as nodules in noncirrhotic livers are more likely to be benign. Hemangiomas, the most common benign tumors, require no followup after diagnostic confirmation if they are small and asymptomatic. Patients with giant, symptomatic hemangiomas or compression of adjacent structures should be referred to hepatobiliary centers for potential surgery. The genetic heterogeneity of hepatocellular adenomas and their epidemiology and prognosis prompted classification of these tumors into four subtypes based on histology and immunohistochemistry. The major complications of hepatocellular adenomas are rupture with bleeding and malignant transformation. Rupture occurs in approximately 30% of cases. The main risk factors are tumor size >5 cm and inflammatory subtype. Hepatocellular adenomas may enlarge during pregnancy due to marked hormonal stimulation. As oral contraceptive pills and anabolic steroids have been associated with hepatocellular adenomas growth, particularly of the hepatocyte nuclear factor1alfa subtype, these drugs should be discontinued. Focal nodular hyperplasia is the second most common benign tumor of the liver. It is most frequent in women aged 20 to 60, and 70% to 90% of cases are asymptomatic. In the absence of a central scar and/or other hallmarks of Focal nodular hyperplasia, with uncertainty between this diagnosis and hepatocellular adenoma, liverspecific contrast agents are indicated.
