What is a heterogeneous mass in liver?
Benign tumors of the liver are a heterogeneous group of lesions whose detection has greatly increased because of the widespread use of imaging techniques. Only a few types, such as cavernous hemangiomas, focal nodular hyperplasia (FNH), hepatic adenoma (HA), and cysts, are frequent enough to be of clinical importance.
What does hypodense mass mean?
Hypodense (less dense): If an abnormality is less dense than the reference structure, we would describe it as hypodense.
Is a hypodense liver lesion cancerous?
concluded that finding a small, hypodense lesion in the liver in a patient with otherwise no definite metastases was a benign finding. Krakora et al. [21], in a study of 153 patients with breast cancer, discovered small hypoattenuating hepatic lesions in 35%.
Does homogeneous mass mean cancer?
With regard to neoplastic conditions, benign soft-tissue tumors generally show well-defined homogeneous contrast enhancement, whereas malignant tumors are usually irregular and show heterogeneous enhancement.
What is the meaning of heterogeneous mass?
Heterogeneous refers to a structure with dissimilar components or elements, appearing irregular or variegated. For example, a dermoid cyst has heterogeneous attenuation on CT. It is the antonym for homogeneous, meaning a structure with similar components.
What does Hypodensity of the liver mean?
Q: What is Liver Hypodensity? No abdominal lymphadenopathy was present. So, hypodensity means that there is an area that appears more diffused when looked at in an x-ray. Hepatic steatosis, also known as fatty liver disease or simply as fatty liver, is probably the most common liver disease.
What is hypodense in CT scan?
The appearance of tissues on a CT scan is described in terms of ‘density’. Darker structures are ‘hypodense or low density’; brighter structures are ‘hyperdense or high density’. Blood Can Be Very Bad is a mnemonic that can be used when faced with interpreting a CT head scan: Blood. Cisterns..
What is heterogeneous mass lesion?
Soft tissue tumors are a heterogeneous group of benign and malignant lesions that develop from various nonepithelial, extraskeletal elements, including adipose tissue, smooth and skeletal muscle, tendon, cartilage, fibrous tissue, blood vessels, and lymphatic structures.
What is difference between Hypodense and Hyperdense?
The appearance of tissues on a CT scan is described in terms of ‘density’. Darker structures are ‘hypodense or low density’; brighter structures are ‘hyperdense or high density’..
What is heterogeneous mass?
Is a heterogeneous mass cancer?
Cancer is a dynamic disease. During the course of disease, cancers generally become more heterogeneous. As a result of this heterogeneity, the bulk tumour might include a diverse collection of cells harbouring distinct molecular signatures with differential levels of sensitivity to treatment.
What causes hypodensity in the right lobe of the liver?
It is may caused by hepatic cysts, hemangioma, liver abscess or liver cancer. Liver hypodensity in the right lobe of the liver usually indicates cystic tumor, such as hepatic cysts and hemangioma. Liver hypodensity is sometimes caused by hepatic fat. Many factors could cause liver hypodensity, but not all indicate liver cancer.
What is the cause of heterogeneous liver masses?
These masses may be benign genetic differences or a result of liver disease. In most cases, a finding of heterogeneous liver is followed by further medical testing to determine the cause of the heterogeneity. A heterogeneous liver can be caused by fatty liver disease, tumors or cirrhosis.
How are hypodense lesions detected in the liver?
The same logic is used to detect hypovascular lesions in the liver. These lesions are detected in the portal venous phase when the normal liver parenchyma appears maximally enhanced. During this phase, the hypovascular tumors remain obscure and appear as hypodense lesions in a relatively hyperdense liver.
What does hypodensity look like on a CT scan?
Liver hypodensity on a CT scan means a lesion of the liver that appear less dense than the surrounding liver tissue.
