REVIEW
Nelson Chen, Kellee Slater
BACKGROUND: Solitary fibrous tumours (SFT) are neoplasms of mesenchymal origin that predominantly arise from the pleura. SFT of the liver (SFTL) are a rare occurrence with little number of cases reported in English literature. Malignant cases of hepatic SFT are an even rarer occurrence. For this reason, the prognostic evaluation of SFTLs is unknown and difficult to measure. METHODS: A search on English literature on "Solitary Fibrous Tumour of the Liver" was conducted on common search engines (PubMed, Google)...

Situs inversus totalis (SIT) is a congenital condition consisting of a mirror image of transposition of the abdominal and thoracic organs occurring in about 1:5000 to 1:10 000 adults. We report on a 60-year-old male with a single colorectal liver metastasis in the Segment 7. The patients underwent a totally laparoscopic sub-segmentectomy. Intraoperative approach on a reverse posterior segment was difficult because of left-sided position of the liver. Postoperative course was uneventful and the patient was discharged after 5 days...

BACKGROUND AND AIM: Endoscopic biliary drainage (EBD) is the mainstay treatment for inoperable malignant distal biliary obstruction (MDBO). Some authorities suggest that metallic stents are more cost-effective than plastic stents in patients with expected survival of at least 6 months. However, studies attempting to define the predictive factors for such survival times are limited. This study aims to develop a scoring system for predicting a survival time of <24 weeks in these patients...

Breast magnetic resonance (MR) imaging is the only breast imaging modality that consistently encompasses extramammary structures in the thorax and upper abdomen. Incidental extramammary findings on breast MR images of patients with a history of breast cancer or other malignancies are significantly more likely to be malignant and may affect staging and treatment. An understanding of the frequency, distribution, and context of extramammary findings on breast MR images and a familiarity with common and uncommon sites of breast cancer metastasis inform the differential diagnosis and prompt the appropriate diagnostic next step, to differentiate benign from malignant findings...

Undifferentiated carcinoma of the ampulla of Vater is a rare disease with unclear and clinical characteristics and prognosis. Here, we report the case of a 61-year-old man with undifferentiated carcinoma of the ampulla of Vater. He presented to our hospital with an increase in hepatobiliary system enzymes that was detected during a health check-up. Imaging and endoscopy demonstrated a tumor with ulcer in the ampulla of Vater, which was diagnosed as a carcinoma by biopsy. No distant metastasis was observed. Subtotal stomach-preserving pancreaticoduodenectomy was performed...

PURPOSE: To assess whether fusion imaging-guided percutaneous microwave ablation (MWA) can improve visibility and targeting of liver metastasis that were deemed inconspicuous on ultrasound (US). MATERIALS AND METHODS: MWA of liver metastasis not judged conspicuous enough on US was performed under CT/US fusion imaging guidance. The conspicuity before and after the fusion imaging was graded on a five-point scale, and significance was assessed by Wilcoxon test. Technical success, procedure time, and procedure-related complications were evaluated...

The diagnosis of hepatocellular carcinoma (HCC) is based on imaging studies particularly in high-risk patients without histologic confirmation. This study evaluated the prevalence and characteristics of false-positively diagnosed HCC in a liver resection cohort for HCC. A retrospective review was performed of 837 liver resection cases for clinically diagnosed HCC between 2005 and 2010 at our institute. High-risk patients with tumors > 1 cm with one or two image findings consistent with HCC and tumors < 1 cm with two or more image findings consistent with HCC with persistently increased serum alpha-fetoprotein (AFP) levels above the normal range with underlying inhibited hepatitis activity underwent liver resection...

BACKGROUND Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor. We present a single-center study on hepatic EHE cases treated by hepatic resection (HR) or liver transplantation (LT). MATERIAL AND METHODS Six HR patients with hepatic EHE were identified during 5 years from 2010 to 2014; EHE represented 0.13% (6 of 4572) of all primary liver tumors. Two LT recipients were also identified during 12 years from 2003 to 2014, who represented 0.06% (2 of 3576) of all adult LT patients. RESULTS Mean age of the patients was 42...

There are diverse protocols to manage patients with recurrent disease after primary cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal carcinomatosis. We describe a case of metachronous liver metastasis after CRS and HIPEC for colorectal cancer, successfully treated with a selective metastectomy and partial graft of the inferior vena cava. A 35-year-old female presented with a large tumour in the cecum and consequent colonic stenosis. After an emergency right colectomy, the patient received adjuvant chemotherapy...

Anti-angiogenic therapies have failed to confer survival benefits in patients with metastatic breast cancer (mBC). However, to date there has not been an inquiry into roles for acquired versus innate drug resistance in this setting. In this study, we report roles for these distinct phenotypes in determining therapeutic response in a murine model of mBC resistance to the anti-angiogenic tyrosine kinase inhibitor sunitinib. Using tumor measurement and vascular patterning approaches, we differentiated tumors displaying innate versus acquired resistance...

Hepatocellular carcinoma (HCC) the most common primary tumor of the liver usually develops in the setting of chronic liver disease. The presentation is usually due to worsening of chronic liver disease or being detected incidentally on imaging. Rarely metastasis to distant organ becomes the presentation. The authors describe a case of a 70-year-old woman who presented with dyspnea of 2 weeks duration. She was diagnosed as having HCC and extensive multiple pulmonary metastases. She was symptomatic only for the pulmonary metastasis with only 2 lesions in the liver...

BACKGROUND: Metastasis of colorectal cancer to the liver is the most common indication for hepatic resection in a western population. Incomplete excision of malignancy due to residual microscopic disease normally results in worse patient outcome. Therefore, a method aiding in the real time discrimination of normal and malignant tissue on a microscopic level would be of benefit. MATERIAL AND METHODS: The ability of fluorescent probe-based confocal laser endomicroscopy (pCLE) to identify normal and malignant liver tissue was evaluated in an orthotopic murine model of colorectal cancer liver metastasis (CRLM)...

Liver magnetic resonance imaging (MRI) is becoming the gold standard in liver metastasis detection and treatment response assessment. The most sensitive magnetic resonance sequences are diffusion-weighted images and hepatobiliary phase images after Gd-EOB-DTPA. Peripheral ring enhancement, diffusion restriction, and hypointensity on hepatobiliary phase images are hallmarks of liver metastases. In patients with normal ultrasonography, computed tomography (CT), and positron emission tomography (PET)-CT findings and high clinical suspicion of metastasis, MRI should be performed for diagnosis of unseen metastasis...

Focal nodular hyperplasia (FNH) is the second most common benign solid liver lesion after hemangioma, occurring more frequently in young women. The prime differential diagnoses include hepatocellular adenoma, hepatocellular carcinoma, and hypervascular metastasis. As the management of FNH is typically conservative, imaging plays a key role in diagnostic pathway, and misdiagnosis may have a major clinical effect. In this article, we describe the ultrasound, computed tomography, and magnetic resonance imaging features of FNH, underlining the importance of typical radiological features that allow a specific noninvasive diagnosis...

Hepatic steatosis can occur because of nonalcoholic fatty liver disease (NAFLD), alcoholism, chemotherapy, and metabolic, toxic, and infectious causes. Pediatric hepatic steatosis is also becoming more frequent and can have distinctive features. The most common pattern is diffuse form; however, it can present in heterogenous, focal, multinodular, perilesional, perivascular, subcapsular, and lobar forms. Focal steatosis and fat sparing can occur because of the presence of veins of Sappey, pancreaticoduodenal vein, and aberrant right and left gastric veins, which drain into the liver as third inflow...

Worldwide, prostate cancer is considered the second most common cancer in men. Most common sites for metastatic disease are lymph nodes and bones. However, isolated liver metastasis from prostate cancer is rare. We present a 75 year-old male with prostate adenocarcinoma diagnosed 7 years ago. With rising PSA, he underwent imaging and found to have isolated hepatic metastasis. After left hepatic lobectomy, his PSA dramatically decreased to < 0.01. Physicians should be aware of isolated hepatic metastasis in patients with prostate cancer...
