The primary tumor is usually colonic adenocarcinoma, melanoma, carcinoid, breast or renal or ovarian cancer. Liver cysts are abnormal growths that can develop in the liver. Although in some cases it is difficult to distinguish these entities with imaging criteria alone, certain cystic focal liver lesions have classic computed tomographic (CT) and magnetic resonance (MR) imaging features, which are important for the radiologist to understand and recognize. Morphologically, they may be classified as Simple or complex. Fluid-fluid levels in a lesion are nonspecific and seen in both benign and malignant lesions. Step 5: Study the superimposed image below. Radiographics 21(4):895-910. Given the negligible enhancement and iodine content of the lesions, this most likely is the result of non-water components of the cystic lesions which are not accounted for by the subtraction algorithm. Although most are benign, in many cases, further workup can be difficult to avoid. CT is usually sufficient for detecting cysts, but in cases of lesions <1 cm, MRI may be more useful in differentiating cysts from subcentimeter metastases. Advances in imaging and interventional techniques and the sharp drop in the . Such lesions will be detected in up to 30% of individuals older than 40 years [5-23]. Significance of Small Pancreatic Cysts Most diagnostic uncertainty is centered on pancreatic cysts <2.5 cm. This case suggests that the liver metastases of solid pancreatic tumor could be cystic. In general, they can be classified as developmental, neoplastic, infectious, inflammatory, or miscellaneous lesions. 71Cystic Liver Lesions A broad range of liver lesions can appear cystic. Hepatocellular carcinoma and hemangioma are the primary liver lesions which are most likely to appear as cystic lesions. The increasing and widespread use of imaging studies has led to an increase in detection of incidental FLL. Important basic imaging features include number, size, location, and distribution of lesions, along with simple or complex morphology. There are mimickers of simple liver cysts that are more dangerous to the patient. Cystic liver lesions, or fluid-containing lesions of the liver, are commonly encountered findings on radiologic examinations that may represent a broad spectrum of entities ranging from benign developmental cysts to malignant neoplasms ( Table 1 ). Hepatocyte phase imaging is usually not needed in order to characterize these lesions; these lesions are hypointense to the surrounding liver parenchyma on hepatocyte phase (Fig. Cystic liver lesions are commonly encountered findings on radiologic examinations and may represent a broad spectrum of entities ranging from benign developmental cysts to malignant neoplasms. characterization of liver lesions in adults with known or suspected focal liver disease1 The purpose of this article is to review the imaging findings utilizing gadoxetic disodium with respect to benign liver lesions and metastatic disease. Cystic lesions of the liver are frequently encountered in clinical practice. Optimal imaging of focal liver lesions EVIEWR Modern diagnostic imaging allows the accurate identification of different focal liver lesions. Cystic lesions of the liver represent a heterogeneous group of disorders, which differ in etiology, prevalence, and clinical manifestations ( table 1 ). Discuss the utility of imaging procedures for detection of liver metastases. Many patients present with vague clinical symptoms and overlapping imaging findings. But in some cases, liver lesions are malignant (cancerous) and should be treated. 1). The assessment of cystic liver lesions is based on imaging characteristics as well as patient demographics, clinical findings, and pertinent history. The prevalence of HCs has been reported as high as 15-18% in the United States. Most liver cysts are found incidentally on imaging studies and tend to have a benign course. The pathology specimen shows a cystic tumor with multiple small cysts and a central scar. Multiple cystic liver lesions on CT | Gut.

Some special cases can mislead the diagnosis of the disease. A minority can cause symptoms and rarely may be associated with serious morbidity and mortality [ 1-3 ]. This imaging pattern may be observed in a wide spectrum of common and uncommon neoplastic or nonneoplastic entities. Calcified Liver MassesOvarian Neoplasms. CT CT scan is the imaging procedure of choice to evaluate liver for metastases. PubMed Google Scholar biliary hamartoma. Detection of HCs is rising, due to vast availability and increased use of abdominal imaging modalities. Detection of HCs is rising, due to vast availability and increased use of abdominal imaging modalities. The preoperative diagnosis of pedunculated or exophytic liver lesions was difficult previously, but with the availability of magnetic resonance imaging (MRI) and multi-detector computed tomography (MDCT) scans, the diagnosis is not that difficult now, but still needs careful examination and interpretation of radiological findings for correct . A multilocular cystic hepatic lesion detected at computed tomography (CT) and magnetic resonance (MR) imaging is a common but nonspecific radiologic finding that can cause potential challenges for differential diagnosis. These are usually benign pseudocysts from pancreatitis or cystic tumors. While benign lesions of congenital and inflammatory origin are relatively common, cystic liver tumors are rare [ 1 ].In many clinical studies, a wide variety of morphological features of cystic liver lesions have been described [2-4]. 2011 Apr . Solitary or multiple. hepatic abscess. In addition to malignant liver lesions, these may include benign solid and cystic liver lesions such as hemangioma, focal nodular hyperplasia (FNH), hepatocellular adenoma, and hepatic cysts. Hemangiomas, especially large ones, may contain large, coarse calcifications; may be seen at CT in 20% of cases or radiography in 10%.

These are difficult to diagnose and difficult to biopsy percutaneously. Because of the overlapping imaging appearances MCBH should also be considered for differential diagnosis of cystic lesion in liver. adult polycystic liver disease. These lesions vary concerning pathogenesis, clinical presentation, and radiological findings. prevalence of benign focal liver lesions in adults is high, with at least one lesion seen in up to 15% of patients, accurate characterization of incidentally detected lesions is an important objective of diagnostic imaging [1]. When multiple cystic lesions are observed throughout the liver parenchyma, the most important diagnostic problem is to exclude cystic liver metastases. The imaging features of liver abscess vary according to its evolution. A diagnostic and therapeutic algorithm is provided. With the correct and appropriate use of imaging, diagnosis may be relatively straightforward and clinical management may be implemented appropriately.

Cystic lesions of the liver carry a broad differential diagnosis: simple cysts. The wide range of Mucinous cyst neoplasm of the liver (MCN-L) comprise less than 5% of all cystic liver lesions and is characterized by the presence of ovarian stroma and absence of bile duct communication. Benign lesions are very common in the liver, and even in patients with primary malignancy, benign lesions unrelated These lesions will become either relatively hyperdense or hypodense to the normal liver. We will discuss the role of multiparametric MRI including T2-weighted imaging (T2WI), diffusion-weighted imaging (DWI) and dynamic post-contrast T1WI imaging for the characterisation of focal liver lesions: to differentiate benign and malignant lesions and characterise subtypes of malignant lesions based on a combination of imaging features. Conclusion. The cystic liver lesion initially resembled a simple liver cyst with fast growth, and then evolved into an abscess-like mass after a short term. Although serology for hydatid disease was negative, the cystic lesion was treated by percutaneous drainage. Cystic lesions of the liver are frequently encountered in clinical practice.
