Abstract
Focal liver lesions (FLLs) have become an increasingly common finding on abdominal imaging, especially asymptomatic and incidental liver lesions. Gastroenterologists and hepatologists often see these patients in consultation and make recommendations for management of multiple types of liver lesions, including hepatocellular adenoma, focal nodular hyperplasia, hemangioma, and hepatic cystic lesions including polycystic liver disease. Malignancy is important to consider in the differential diagnosis of FLLs, and healthcare providers must be familiar with the diagnosis and management of FLLs. This American College of Gastroenterology practice guideline uses the best evidence available to make diagnosis and management recommendations for the most common FLLs.

Abstract
Background and study aims Symptomatic simple hepatic cysts require treatment, with several guidelines recommending laparoscopic deroofing. However, cysts located in the posterosuperior segments are considered poor candidates for this procedure. Gastrointestinal endoscopes are more flexible and able to reach less accessible areas than laparoscopes. This study aimed to evaluate the utility of endoscopic transgastric hepatic cyst deroofing (ETGHCD) for treatment of simple hepatic cysts. Patients and methods Seven patients with simple hepatic cysts were evaluated between June 2021 and October 2023. The success rate, procedure time, post-procedure length of hospital stays, complications, pathologic diagnosis, and efficacy were recorded. Results Eleven cysts in seven patients (5 men; mean age 65.5 (standard deviation [SD] 8.5) years) were successfully treated without any complications. The mean procedure time was 65.6 minutes (SD 17.2). Mean post-procedure hospitalization was 4.4 days (SD 1.0). The pathologic diagnosis of 11 cysts showed simple hepatic cysts. The size of the cysts was significantly decreased from 337.0 cm 3 (SD 528.8) to 5.2 cm 3 (SD 6.3) 1 month after ETGHCD. During the median 12.7-month follow-up in seven patients, the cysts showed a 99.6% reduction with no recurrence. Conclusions ETGHCD provided a feasible, safe, effective, and minimal invasive alternative approach for the treatment of simple hepatic cysts.

Abstract
This study aims to compare the tracking algorithms provided by the OpenCV library to use on ultrasound video. Despite the widespread application of this computer vision library, few works describe the attempts to use it to track the movement of liver tumors on ultrasound video. Movements of the neoplasms caused by the patient`s breath interfere with the positioning of the instruments during the process of biopsy and radio-frequency ablation. The main hypothesis of the experiment was that tracking neoplasms and correcting the position of the manipulator in case of using robotic-assisted surgery will allow positioning the instruments more precisely. Another goal of the experiment was to check if it is possible to ensure real-time tracking with at least 25 processed frames per second for standard definition video. OpenCV version 4.5.0 was used with 7 tracking algorithms from the extra modules package. They are: Boosting, CSRT, KCF, MedianFlow, MIL, MOSSE, TLD. More than 5600 frames of standard definition were processed during the experiment. Analysis of the results shows that two algorithms-CSRT and KCF-could solve the problem of tumor tracking. They lead the test with 70% and more of Intersection over Union and more than 85% successful searches. They could also be used in real-time processing with an average processing speed of up to frames per second in CSRT and 100 + frames per second for KCF. Tracking results reach the average deviation between centers of neoplasms to 2 mm and maximum deviation less than 5 mm. This experiment also shows that no frames made CSRT and KCF algorithms fail simultaneously. So, the hypothesis for future work is combining these algorithms to work together, with one of them-CSRT-as support for the KCF tracker on the rarely failed frames.

Abstract
Pyogenic liver abscesses (PLAs) are a rare condition in North America and Europe and, rarer still, the cause of septic shock. This case report will describe the rare occurrence of a PLA producing septic shock in a 36-year-old male residing in the United Kingdom following a case of complicated appendicitis. The patient presented to the emergency department (ED) with a three-week history of intermittent loose stools, cramping abdominal pain, recurrent fevers, a heart rate of 111 beats per minute, a blood pressure of 94/58 mmHg, and a fever of 40.1 degrees Celsius. Despite prompt broad spectrum antibiotic administration and three liters of fluid resuscitation, the patient remained shocked which led to an ICU admission. A CT scan prior to transfer found a 7 cm x 6 cm x 6 cm lesion representing a liver abscess (LA) as well as gross inflammatory change affecting the distal small bowel. The LA was managed through insertion of a percutaneous drain under ultrasound guidance performed by the interventional radiology team, as well as ongoing IV antibiotics. Following growth of the gut commensal Streptococcus constellatus from the abscess fluid culture, a colonoscopy was performed which found a severely distorted and inflamed terminal ileum with an impassable stricture, raising not only the suspicion of appendicitis but also Crohn’s disease. Following the colonoscopy, after a total of 10 days admission, the patient was allowed to go home with a four-week course of oral co-amoxiclav. After discharge, the patient’s case was discussed in the gastroenterology inflammatory bowel disease (IBD) multi-disciplinary team meeting due to concerns raised about possible Crohn’s disease from the admission CT and following colonoscopy findings. Given the absence of relevant IBD symptoms, a reassuring outpatient MRI small bowel scan (found considerable resolution of the right iliac fossa inflammatory process) and a fecal calprotectin of 29 four months post discharge (normal=0-51 μg/g), it was concluded the terminal ileum changes were most likely accounted for by a complicated course of appendicitis. When reviewed in a telephone clinic 10 weeks post discharge, he was found to have no persistent gastrointestinal (GI) symptoms and was subsequently discharged. This case highlights the importance of comprehensive imaging and colonoscopy in the work up of those patients with PLAs with no otherwise evident precipitating factor.

Abstract
Simple hepatic cysts are typically saccular, thin-walled masses with fluid-filled epithelial lined cavities that arise from aberrant bile duct cells during embryonic development. With the development of diagnostic modalities such as ultrasonography, computed tomography and magnetic resonance imaging, simple hepatic cysts are seen with relative frequency in daily clinical examination. US is the most useful and noninvasive tool for the diagnosis of simple hepatic cysts, and can generally differentiate simple hepatic cysts from abscesses, hemangiomas and malignancies. Cysts with irregular walls, septations, calcifications or daughter cysts on US should be evaluated with enhanced CT or MRI to differentiate simple hepatic cysts from cystic neoplasms or hydatid cysts.Growth and compression of hepatic cysts cause abdominal discomfort, pain, distension and dietary symptoms such as nausea, vomiting, a feeling of fullness and early satiety. Complications of simple hepatic cysts include infection, spontaneous hemorrhage, rupture, and external compression of biliary tree or major vessels.Asymptomatic simple hepatic cysts should be observed. Treatment for symptomatic simple hepatic cysts includes percutaneous aspiration, aspiration followed by sclerotherapy, and surgery. The American College of Gastroenterology clinical guidelines recommend laparoscopic fenestration based on its high success rate and low invasiveness. Percutaneous procedures for treatment of simple hepatic cysts are particularly effective for the immediate palliation of patient symptoms; however, they are not generally recommended because of the high rate of recurrence.Management of simple hepatic cysts requires correct differentiation from neoplasms and infections, and the selection of a reliable treatment.

Abstract
We herein report a case of intraperitoneal abscess as a postoperative complication of gastric endoscopic submucosal dissection (ESD). A 70-year-old man who underwent ESD for early gastric cancer sought consultation for abdominal pain on postoperative day 28. Abdominal computed tomography revealed intraperitoneal abscess rupture. He underwent image-guided laparoscopic irrigation. His postoperative course was favorable, and he was discharged after 27 days. Intraoperatively, a white plaque adhering to the gastric wall was surrounded by a large pus volume and suspected to be ESD-associated. We present this case with a literature review of the association between intraperitoneal abscess and ESD.

Abstract
INTRODUCTION Advanced colorectal cancer is known to be associated with liver abscesses. A strategy to treat liver abscesses as early as possible is necessary to ensure high surgical curability before the cancer progresses and to prevent worsening nutritional status of the patient during surgery. PRESENTATION OF CASE An 82-year-old woman was hospitalized due to fever. A 10 cm in diameter liver abscess and advanced colon cancer were diagnosed. After conservative treatment of the liver abscess with antibiotics and puncture drainage, colorectal cancer surgery was performed on a standby basis. DISCUSSION We propose that empiric antibiotic therapy should be administered early in cases of liver abscesses that may require early colorectal surgery. Abscess drainage should be performed promptly if the abscess is of a size that can be punctured easily. CONCLUSION In patients with advanced colorectal cancer complicated by liver abscesses that required early surgery, prompt drainage of the liver abscesses is mandatory.

Abstract
Simple liver cysts are usually asymptomatic, and complications are uncommon. However, infection of cysts can very occasionally occur, and this troublesome complication requires treatment. An 87-year-old woman admitted for dyspnea, abdominal discomfort, fever, and mild icterus underwent ultrasonographic (US) and computed tomography (CT) examinations, and a huge cystic lesion was identified in the right hepatic lobe. The diagnosis of an infected gigantic liver cyst was made by abdominal CT and percutaneous transhepatic drainage under ultrasonographic guidance. The pus viscosity was so high that pus drainage was ineffective. Bacterial culture was positive for Klebsiella pneumoniae. The cyst diameter was approximately 21 cm, and the total pus discharge was 3.8 l. Emergency operation to fenestrate the cyst wall relieved the patient's critical condition. This report is clinically significant because 3.8 l of pus may be one of the largest reported quantity of drained pus from an infected cyst. We found no reports of > 3.8 l of drained pus in an English literature search. It is also very rare that imaging identified postoperative liver regeneration filling the huge empty space previously occupied by the cyst. Large liver cysts in older people should be carefully followed, preparing for the rare possibility of infection.

Abstract
Pyogenic liver abscesses are classified by the bacteria that have caused the abscess because this guides treatment and can point to the underlying cause. The most common cause is biliary disease. The diagnosis is made by imaging. Treatment is a combination of antibiotics and percutaneous drainage. Amebic liver abscess is caused by extraintestinal spread of Entamoeba histolytica. E histolytica is spread by fecal-oral transmission and typically colonizes the gastrointestinal tract. It is diagnosed based on imaging and the mainstay of treatment is metronidazole. Only about 15% of cases require percutaneous drainage. The prognosis is good, with almost universal recovery.

Abstract
Cholecystectomy is the gold standard surgical treatment for acute calculous cholecystitis. Only approximately 0.4 % of these patients subsequently develop choledocholithiasis. The incidence of hepatic abscesses in these patients is unknown, but is likely low, considering there are approximately 2–15 cases of hepatic abscesses per 100,000 people in the US. The authors report the case of a 62-year-old man whose CT scan revealed hepatic abscesses secondary to choledocholithiasis, eight years after a cholecystectomy.

Abstract
Simple hepatic cysts are usually asymptomatic but can rarely result in life-threatening complications such as haemoperitoneum secondary to rupture. A 70-year-old woman with known simple hepatic cyst presented with acute chest pain and dyspnoea. The initial diagnosis was pulmonary embolism, and anticoagulation was commenced. However, she subsequently collapsed with haemodynamic instability. CT revealed a large hepatic cyst haematoma with rupture into the peritoneal cavity. The patient underwent emergency laparotomy, haemostasis and partial deroofing of the cyst. Retrospective review of CT scans suggested that the bleed had begun on presentation but was exacerbated by anticoagulation. To our knowledge, this is the first report of haemorrhagic hepatic cyst associated with acute anticoagulation. We discuss several important clinical lessons including cyst rupture as a possible cause of chest pain, the need for careful review of imaging and the choice of anticoagulation in patients with known simple hepatic cyst.

Abstract
Liver abscesses containing hypervirulent Klebsiella pneumoniae have emerged during the past 2 decades, originally in Southeast Asia and then worldwide. We hypothesized that hypervirulent K. pneumoniae might also be emerging in France. In a retrospective, monocentric, cohort study, we analyzed characteristics and outcomes for 199 consecutive patients in Paris, France, with liver abscesses during 2010-2015. We focused on 31 patients with abscesses containing K. pneumoniae. This bacterium was present in most (14/27, 52%) cryptogenic liver abscesses. Cryptogenic K. pneumoniae abscesses were more frequently community-acquired (p<0.00001) and monomicrobial (p = 0.008), less likely to involve cancer patients (p<0.01), and relapsed less often (p<0.01) than did noncryptogenic K. pneumoniae liver abscesses. K. pneumoniae isolates from cryptogenic abscesses belonged to either the K1 or K2 serotypes and had more virulence factors than noncryptogenic K. pneumoniae isolates. Hypervirulent K. pneumoniae are emerging as the main pathogen isolated from cryptogenic liver abscesses in the study area.

Abstract
Simple hepatic cysts are common benign liver lesions that usually have no malignant capability. They are generally asymptomatic and are often found incidentally by abdominal imaging procedures. Treatment becomes necessary, however, when huge hepatic cysts cause symptoms and develop complications, such as hemorrhage, adjacent organ damage, and infection. Several therapeutic options have been performed for symptomatic and huge cysts, including the aspiration of cystic fluid, infusion of various sclerosing agents, and surgical intervention. The optimal management of huge hepatic cysts is controversial and each option has its complications and limitations. This paper reports a case of a 66-year-old woman diagnosed with a simple hepatic cyst 2 years earlier, who was referred to hospital due to abdominal pain. The diagnosis was a huge hepatic cyst with symptoms by abdominal imaging studies. During the follow-up period, the huge cysts resolved spontaneously without treatment.

Abstract
Objective An infectious hepatic cyst (IHC) is a hepatic cyst complicated with secondary infection and is generally assumed to be rare. However, we have experienced no small number of patients with IHC in recent clinical practice. We therefore examined the incidence and clinical characteristics of IHC. Methods The medical records of patients with IHC who were hospitalized at our institution between January 2012 and December 2016 were retrospectively reviewed. Their demographic factors, biochemical, bacteriological, imaging, and treatment results were explored and compared with those of patients with pyogenic liver abscess (PLA). Patients Twelve patients with IHC and 39 with PLA were identified. Results The IHCs were significantly larger in diameters than the PLAs, and patients with IHCs tended to be older and more often women than those with PLAs. IHCs showed characteristic imaging features, including heterogeneous contents with occasional fluid-debris levels, a thickened cystic wall with rim enhancement, perilesional edema and hyperaemia. Patients with IHCs had a significantly shorter hospital stay than those with PLAs. Conclusion Physicians should note that IHCs are not rare. A careful imaging evaluation can suggest an IHC, and the timely aspiration of the content can lead to an accurate diagnosis. The cystic wall may keep the infectious material confined within the IHC, resulting in the observed good treatment outcome with catheter drainage.

Abstract
Identifying metastatic tumor growth at an early stage has been one of the biggest challenges in the treatment of lung cancer. By genetic lineage tracing approach in a conditional model of Non-Small Cell Lung Cancer (NSCLC) in mice, we demonstrate that cystic lesions represent an early stage of metastatic invasion. We generated a mouse model for NSCLC which incorporated a heritable DsRed fluorescent tag driven by the ubiquitous CAG promoter in the alveolar type II cells of the lung. We found early cystic lesions in a secondary organ (liver) that lacked the expression of bona fide lung makers namely Scgb1a1 and surfactant protein C Sftpc and were DsRed positive hence identifying lung as their source of origin. This demonstrates the significant potential of alveolar type II cells in orchestrating the process of metastasis, rendering it as one of the target cell types of the lung of therapeutic importance in human NSCLC.

Abstract
A 21-year-old male with no significant past medical history, presented with right upper quadrant (RUQ) abdominal pain along with fevers and chills. Lab work revealed leukocytosis, anemia, and slightly elevated alkaline phosphatase. Viral serology for hepatitis B virus, hepatitis C virus, and human immunodeficiency virus were negative and he was immunocompetent. Computed tomography imaging revealed hepatic abscesses, the largest measuring 9.5 cm. Empiric antibiotics were started and percutaneous drains were placed in the abscesses. Anaerobic cultures from the abscesses grew Fusobacterium nucleatum. This is a gram negative anaerobic bacteria; a normal flora of the oral cavity. Fusobacterium is most commonly seen in Lemiere’s disease, which is translocation of oral bacteria to the internal jugular vein causing a thrombophlebitis and subsequent spread of abscesses. Our patient did not have Lemiere’s, and is the first case described of fusobacterium pyogenic liver abscess in a young immunocompetent male with good oral hygiene. This case was complicated by sepsis, empyema, and subsequent abscesses located outside the liver. These abscesses’ have the propensity to flare abruptly and can be fatal. This case not only illustrates fusobacterium as a rare entity for pyogenic liver abscess, but also the need for urgent diagnosis and treatment. It is incumbent on physicians to diagnose and drain any suspicious hepatic lesions. While uncommon, such infections may develop without any overt source and can progress rapidly. Prompt drainage with antibiotic therapy remains the cornerstone of therapy.

Abstract
Microbial contamination of the liver parenchyma leading to hepatic abscess (HA) can occur via the bile ducts or vessels (arterial or portal) or directly, by contiguity. Infection is usually bacterial, sometimes parasitic, or very rarely fungal. In the Western world, bacterial (pyogenic) HA is most prevalent; the mortality is high approaching 15%, due mostly to patient debilitation and persistence of the underlying cause. In South-East Asia and Africa, amebic infection is the most frequent cause. The etiologies of HA are multiple including lithiasic biliary disease (cholecystitis, cholangitis), intra-abdominal collections (appendicitis, sigmoid diverticulitis, Crohn's disease), and bile duct ischemia secondary to pancreatoduodenectomy, liver transplantation, interventional techniques (radio-frequency ablation, intra-arterial chemo-embolization), and/or liver trauma. More rarely, HA occurs in the wake of septicemia either on healthy or preexisting liver diseases (biliary cysts, hydatid cyst, cystic or necrotic metastases). The incidence of HA secondary to Klebsiella pneumoniae is increasing and can give rise to other distant septic metastases. The diagnosis of HA depends mainly on imaging (sonography and/or CT scan), with confirmation by needle aspiration for bacteriology studies. The therapeutic strategy consists of bactericidal antibiotics, adapted to the germs, sometimes in combination with percutaneous or surgical drainage, and control of the primary source. The presence of bile in the aspirate or drainage fluid attests to communication with the biliary tree and calls for biliary MRI looking for obstruction. When faced with HA, the attending physician should seek advice from a multi-specialty team including an interventional radiologist, a hepatobiliary surgeon and an infectious disease specialist. This should help to determine the origin and mechanisms responsible for the abscess, and to then propose the best appropriate treatment. The presence of chronic enteric biliary contamination (i.e., sphincterotomy, bilio-enterostomy) should be determined before performing radio-frequency ablation and/or chemo-embolization; substantial stenosis of the celiac trunk should be detected before performing pancreatoduodenectomy to help avoid iatrogenic HA.

Abstract
Focal liver lesions (FLL) have been a common reason for consultation faced by gastroenterologists and hepatologists. The increasing and widespread use of imaging studies has led to an increase in detection of incidental FLL. It is important to consider not only malignant liver lesions, but also benign solid and cystic liver lesions such as hemangioma, focal nodular hyperplasia, hepatocellular adenoma, and hepatic cysts, in the differential diagnosis. In this ACG practice guideline, the authors provide an evidence-based approach to the diagnosis and management of FLL.

Abstract
BACKGROUND Mucinous cystic neoplasms of the liver (hepatobiliary cystadenomas) are rare neoplastic lesions. Such cysts are often incorrectly diagnosed and managed, and carry a risk of malignancy. The objective of this study was to review the surgical experience with these lesions over 15 years. METHODS A retrospective chart review identified consecutive patients undergoing surgery for liver cystadenomas from 1997-2011. Clinical data were collected and summarized. RESULTS Thirteen patients (mean age 51 years, 12/13 females) with cysts 4.6-18.1 cm were identified. Most cysts were located in the left lobe/centrally (11/12) and had septations (8/13). Mural nodularity was infrequent (3/13). Nine patients had liver resection/enucleation, whereas four had unroofing. Frozen section analysis had a high false-negative rate (4/6). All patients had cystadenomas, of which two had foci of invasive carcinoma (cystadenocarcinoma) within mural nodules. There was no 90-day mortality. All but one patient (myocardial infarction) were alive at a median follow-up of 23.1 months. No patient with unroofing has developed malignancy to date. CONCLUSIONS Non-invasive hepatobiliary cystadenomas present as large central/left-sided cysts in young or middle-aged women. Associated malignancy was relatively uncommon and found within mural nodules. Intra-operative frozen section analysis was ineffective at ruling out cystadenomas. Complete excision is recommended, but close follow-up might be considered in patients with a prohibitive technical or medical risk, in the absence of nodularity on high-quality imaging.

Abstract
BACKGROUND Liver cysts are common, occurring in up to 5% of the population. For many types of cysts, a variety of different treatment options exist and the preferred management is unclear. METHODS A PubMed and Medline literature review was undertaken and articles pertaining to the diagnosis and management of cystic lesions within the liver were retrieved. RESULTS Therapy for symptomatic cysts may incorporate aspiration with sclerotherapy or de-roofing. Polycystic liver disease presents a unique management problem because of the high morbidity and mortality rates from intervention and high rates of recurrence. Careful patient counselling and assessment of symptom index is essential before embarking on any treatment. New medical treatments may ameliorate symptoms. Acquired cystic lesions in the liver require a thorough work-up to fully characterize the abnormality and direct appropriate treatment. Hydatid cysts are best treated by chemotherapy, followed by some form of surgical intervention (either aspiration and sclerotherapy or surgery). Liver abscesses can be effectively treated by aspiration or drainage. CONCLUSION All patients with cystic lesions in the liver require discussion at multidisciplinary meetings to confirm the diagnosis and determine the most appropriate method of treatment.

Abstract
INTRODUCTION Hemangiopericytomas (HPCs) are rare vascular tumors with a high malignant potential. Hepatic metastases from HPC are very infrequent and usually show a distinctive solid aspect with a surrounding pseudocapsule. PRESENTATION OF CASE A 37-year-old man with a previous medical history of recurrent spinal hemangiopericytoma with a 9cm×7cm cystic hepatic mass detected on follow-up. Contrast enhanced US and MRI confirmed the presence the lesion showing mixed (solid and cystic) content. Parasitic and viral serology plus serum tumoral markers (CEA, ca 19.9, ca 125, AFP) tests, upper and lower endoscopy and general laboratory tests were normal and extended left lobectomy was performed. Histopathologic study confirmed the diagnosis of multifocal metastasic hemangiopericytoma with moderate CD-34, CD-99 and Bcl-2 positivity after immunohistochemical staining. After 1-year follow-up the patient does not present any evidence of abdominal recurrence but a skull base recurrence has been detected. DISCUSSION Liver metastasis from spinal HPC are uncommon and do not have cystic appearance so radiologic diagnosis can be challenging. In spite of the presence of previously diagnosed HPC context, the presence of a liver cystic mass in a young patient makes necessary to discard a number much more frequent benign and malignant diagnosis before metastatic disease can be confirmed. CONCLUSION The presence of a cystic hepatic mass makes it mandatory to rule out a number neoplasms other than metastasic HPC before a definitive diagnosis is made. In addition to local radiotherapy and antiangiogenic agents, surgery can be useful to treat liver dissemination.

Abstract
OBJECTIVE Hemorrhage within a hepatic cyst (hemorrhagic hepatic cyst, HHC) is a complication of liver cysts that is difficult to differentiate from other neoplastic entities on imaging. Even when accurately diagnosed, there has been a lack of consensus on the optimal treatment strategy. After presenting our experience with a patient treated via laparoscopy, we aimed to conduct a review of the literature on HHCs. METHODS A computerized search in Medline, PubMed, Google Scholar, and The Cochrane Collaboration was carried out for journal articles or abstracts published from 1950 to 2011. RESULTS A total of 24 patients with HHCs were identified from 1983 to 2011. The cohort had an even gender distribution with a mean age of 62.7 years. Most patients presented with abdominal pain (80 %), while three (14 %) patients were asymptomatic at the time of presentation. CT imaging and ultrasound were unable to accurately diagnose HHC, whereas hyperintensity on MRI was a reliable diagnostic tool. Three (13 %) patients were managed conservatively with observation. Seven (30 %) patients had percutaneous transhepatic drainage. Among these, two patients experienced recurrence that required repeat treatment. Two (9 %) patients underwent open unroofing of their HHC and one (4 %) laparoscopically, without recurrences. Seven (30 %) patients underwent hepatic resection, whereas six (26 %) patients had a cyst enucleation for their HHCs. All patients had uneventful recoveries, with a mean follow-up of 25 months. CONCLUSIONS MRI is a reliable diagnostic tool in the setting of an HHC. Laparoscopic unroofing of HHCs may represent a less morbid and safe treatment modality with low recurrence rates. Given the low level of clinical evidence available so far, these results should be interpreted with caution.

Abstract
BACKGROUND Liver cysts are common, occurring in up to 5% of the population. For many types of cysts, a variety of different treatment options exist and the preferred management is unclear. METHODS A Pubmed and Medline literature review using key words non-parasitic hepatic cysts, polycystic liver disease, echinococcus, hydatid cysts parasitic cysts, Caroli's disease, cystadenoma; liver abscess, surgery, aspiration and treatment was undertaken and papers pertaining to the diagnosis and management of cystic lesions within the liver were retrieved. RESULTS Asymptomatic simple cysts in the liver require no treatment. Therapy for symptomatic cysts may incorporate aspiration with sclerotherapy or de-roofing. At present, insufficient evidence exists to recommend one over the other. Polycystic liver disease presents a unique management problem because of high morbidity and mortality rates from intervention and high rates of recurrence. Careful patient counselling and assessment of symptom index is essential before embarking on any treatment. New medical treatments may ameliorate symptoms. Acquired cystic lesions in the liver require a thorough work-up to fully characterize the abnormality and direct appropriate treatment. Hydatid cysts are best treated by chemotherapy followed by some form of surgical intervention (either aspiration and sclerotherapy or surgery). Liver abscesses can effectively be treated by aspiration or drainage. With improved antimicrobial efficacy, prolonged treatment with antibiotics may also be considered. CONCLUSION All patients with cystic lesions in the liver require discussion at multi-disciplinary meetings to confirm and the diagnosis and determine the most appropriate method of treatment.
