Focal nodular hyperplasia (FNH) is a noncancerous liver growth that is usually asymptomatic and discovered incidentally. It is made up of abnormal blood vessels and liver cells that form a characteristic central scar. FNH is typically benign and does not usually require treatment unless it causes symptoms or uncertainty about the diagnosis.

What is focal fatty?
"Focal fatty infiltration" refers to the accumulation of fat in a specific area or focal point within an organ, commonly seen in the liver. It is usually a benign condition and does not typically cause symptoms. However, it can sometimes be a sign of underlying liver disease or metabolic abnormalities.
What is focal hemangioma?
Focal hemangioma is a benign tumor made up of small blood vessels. It is typically found in the liver and is usually asymptomatic, but can cause pain or other complications if it enlarges. Treatment is generally not required unless the hemangioma grows significantly or causes symptoms.
The distance from lens to focal point is called?
The distance from a lens to the focal point is called the focal length.
What is the distance from the center of a mirror to a focal point called?
The distance from the center of a mirror to the focal point is called the focal length.
What is the distance from the center of a mirror to the focal point called?
The distance from the center of a mirror to the focal point is called the focal length.
What is a discrete nodule of the liver?
A discrete nodule of the liver refers to a well-defined, localized mass or lesion within the liver tissue. These nodules can be benign, such as hemangiomas or focal nodular hyperplasia, or malignant, indicating potential liver cancer. Their presence is often detected through imaging studies like ultrasound, CT scans, or MRI and may require further evaluation to determine their nature and appropriate management.
What is hypoattenuating liver lesions?
Hypoattenuating liver lesions are areas within the liver that appear darker on imaging studies, such as CT scans, compared to the surrounding liver tissue. This decreased attenuation typically indicates the presence of fluid or fat, and these lesions can be benign, like hepatic cysts or focal nodular hyperplasia, or malignant, such as liver tumors. Further evaluation, including additional imaging or biopsy, may be necessary to determine the nature of these lesions.
What is a nodular liver and cirrhosis of liver?
When there is damage to the liver, it attempts to repair itself. The remaining cells (mainly hepatocytes, but also oval cells) - undergo mitotic division in order to replace damaged or dead cells. This process is known as hyperplasia. When hyperplasia occurs in the liver, it results in nodular formations of new cells. A cirrhotic liver is an end-stage liver. It cannot be repaired, and if the person is to live they will need a transplant. A cirrhotic liver will be diffusely (all-over) covered with nodules, where the liver has attempted to regenerate. It will also have scar-tissue and fibrosis as a result of the damage to the liver.
What is Nodular Hyperplasia of the Thyroid?
Hyperplasia of the Thyroid gland occurs as a result of dyshormonogenic goiter, endemic goiter, Graves' disease, or due to multinodular goiter.
What does a 18 hounsfield unit low attenuation liver lesion mean?
An 18 Hounsfield unit low attenuation liver lesion typically indicates a region in the liver that has lower density compared to surrounding liver tissue, which may suggest the presence of a benign lesion such as a cyst, hemangioma, or focal nodular hyperplasia. However, it can also indicate potential malignancies or other pathologies depending on the clinical context and imaging characteristics. Further evaluation, such as additional imaging or a biopsy, may be necessary to determine the exact nature of the lesion. Always consult a healthcare professional for an accurate diagnosis and management plan.
What is hyperintense intraheptic lesion of liver?
A hyperintense intrahepatic lesion of the liver refers to an area within the liver that appears brighter than the surrounding tissue on imaging studies, such as MRI or CT scans. This increased intensity can indicate various conditions, including benign lesions like hemangiomas or focal nodular hyperplasia, as well as malignant tumors or metastatic disease. Further evaluation, such as biopsy or advanced imaging techniques, may be necessary to determine the exact nature of the lesion. Clinical correlation with symptoms and laboratory tests is also essential for accurate diagnosis.
What if you have hyperdense liver lesions?
Hyperdense liver lesions can indicate various conditions, including benign tumors like hemangiomas or focal nodular hyperplasia, as well as malignant lesions such as hepatocellular carcinoma. It's crucial to evaluate these lesions through imaging studies, such as CT or MRI, to determine their nature and potential underlying causes. A biopsy may be necessary for definitive diagnosis, and treatment options will depend on the specific diagnosis and the patient's overall health. Always consult with a healthcare professional for personalized assessment and management.
What are the possible conclusions of a Ct scan reporting a subcentimeter hypodense lesion of the liver?
A CT scan reporting a subcentimeter hypodense lesion in the liver may lead to several possible conclusions. It could represent a benign condition, such as a hemangioma or a focal nodular hyperplasia, but it may also raise suspicion for a malignant process, such as a hepatocellular carcinoma or metastatic disease, especially if there is a history of cancer. Further evaluation, such as MRI or follow-up imaging, may be necessary to determine the nature of the lesion. Ultimately, clinical correlation and possibly a biopsy may be required for definitive diagnosis.
What is hepatic masses?
Hepatic masses are abnormal growths or lesions in the liver, which can be benign (non-cancerous) or malignant (cancerous). Common types include hepatocellular carcinoma, hemangiomas, and focal nodular hyperplasia. These masses can vary in size and may cause symptoms such as abdominal pain or jaundice, but some may be asymptomatic and discovered incidentally during imaging studies. Diagnosis often involves imaging techniques like ultrasound, CT scans, or MRIs, and treatment depends on the type and stage of the mass.
What is the cause of a small liver?
Cirrhosis and nodular cirrhosis can cause a small liver. Cirrhosis can be caused by alcohol abuse, hepatitis B and C, fatty liver disease, or something else.
What is nodular mucosa of the duodenal bulb?
There are several diseases and disorders that present as nodular mucosa of the duodenal bulb. Some examples are, heterotopic gastric mucosa, benign lymphoid hyperplasia, Brunner gland hyperplasia, Cronkhite-Canada syndrome and Peutz-Jeghers syndrome.small nodularity in the bulb of duodenum
What is esophagogastric mucosa showing squamous hyperplasia and focal active chronic inflammation?
Esophagogastric mucosa with squamous hyperplasia and focal active chronic inflammation indicates a pathological condition affecting the lining of the esophagus and stomach. Squamous hyperplasia refers to an increase in the number of squamous cells, often as a response to irritation or injury. The presence of focal active chronic inflammation suggests ongoing inflammation that may be due to factors like gastroesophageal reflux disease (GERD) or chronic irritation. This combination can lead to symptoms such as dysphagia or heartburn and may require further investigation to determine the underlying cause.
