Question 1

what is the cause of low attenuation lesion in your kidney?

Accepted Answer

Several causes: Can be a cyst or several possibilities; best to check with your doctor or see a nephrologist.

Question 2

incidental low attenuation lesion" found in kidney. 7mm in size. what does "low attenuation" mean?

Accepted Answer

Low attenuation: means it absorbs less xrays.  Usually this means that it is something less dense than adjacent tissue.  For example, a fluid filled structure(such as a cyst) has lower attenuation than a solid mass.  In the kidney, an incidental low attenuation lesion usually indicates a benign cyst.  This can be confirmed with an ultrasound.

Question 3

had abdominal ct that stated, "incidental low attenuation lesion in left kidney." er doctor said most likely a cyst. terrified...what does this mean?

Accepted Answer

Probably a cyst: simple cysts in the kidney are common and usually no cause for concern. They are benign and cause no problems health wise. Cysts do not become cancers. If there is any doubt about the diagnosis, a renal ultrasound is the best study to confirm the presence of a cyst.

Question 4

bilateral subcentimeter low attenuation lesions in kidneys?

Accepted Answer

Cysts: That typically represents cysts. Bilateral cystic disease can be either a normal variant if a small number and age of the patient, or polycystic kidney disease.

Question 5

i have a low attenuation liver lesion more than 5mm. please tell me what this means ?

Accepted Answer

Usually benign: Attenuation is like density on a CT.  A high attenuation tissue like bone, will appear white on a CT, whereas low attenuation (less dense substances like fluid) appear darker. In the liver, most low attenuation lesions are hemangiomas, which are benign, however your Dr can best determine if other risk factors or findings (cirrhosis, hepatitis etc,) warrant further evaluation of your lesion.

Question 6

low attenuation lesion in liver measuring more than .5 mm. what does this mean? does this mean i have cancer. lipase elevated 400 dr didnt seemed concerned but i am scared

Accepted Answer

Lesion: In cases like this I sit down with the radiologist who interpreted the ct scan and ask advice as to possible diagnosis, how concerning is the lesion, what other studies, if any, would shed more light on the diagnosis, what specialists may be helpful. With one lesion, yours may well be benign, a hemangioma for example. But again, I need advice from my fellow physicians about further workup,

Question 7

abd ct w/ contrast 4mm low-attenuation lesion right hepatic lobe
present likely a benign cyst or hemangioma too small to characterize need follow up?

Accepted Answer

This is not uncommon: Benign lesions like the one/s you have are quite frequently seen when CT scan of the abdomen is done for any reason.Your test ordering doctor, then has to help you sort it out. We start by asking: why was the CT scan done in the first place? What was the doctor looking for in the abdomen/liver?
Follow up CT scan is often recommended by radiologist but it is frequently not necessary, but it depends

Question 8

ct scan shows a possible lesion at head of pancreas with focal low attenuation mild prominence of the pancreatic duct. no symptoms. can you explain.

Accepted Answer

No: That has to be explained in a clinical context, meaning: the doctor who examined you and ordered the study would be the best to explain, at times after conferring with the radiologist who wrote the report, wish you well

Question 9

what does this mean on my ct scan? there is a 3.2 cm low-attenuation lesion in the left adnexa. there is no evidence of pelvic lymphadenopathy or free fluid. findings: low-attenuation lesion in the left maxillary consistent with ovarian cyst?

Accepted Answer

: All imaging results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, nothing you reported is a cause for concern.    Wish you good health!

Question 10

diffuse mild low attenuation hepatic steatosis
several sub centimeter lesions is the something to worry about ?

Accepted Answer

Liver lesions: Fatty liver and liver lesions concerning.
I would suggest further testing with CT or MRI and if need see liver specialist.
