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

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

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

Kidney (Definition)

The kidneys are paired organs that lie on either side of the vertebral column. Part of their critical functions include the excretion of urine and removal of nitrogenous wastes products from the blood. They regulate acid-base, electrolyte, fluid balance and blood pressure. Through hormonal signals, the kidneys control the ...Read more

Have possible hemorrhagic cyst on kidney. Lesion middle kidney. Having light bleeding. Can this b a sign it's ruptured or what would cause this?

Ans: There are many possibilities for the bleeding. First you must be sure it is not vaginal. If not then go to doctor and have a urine dip. Hydrate and see if blood resolves if not further testing is needed

Is a kidney lesion something to worry about?

Is a kidney lesion something to worry about?

Depends.: Some lesions are benign, some malignant, and many unknown until treatment or a biopsy is performed. Many tumors, cysts, or kidney stones that are benign do not need treatment, and may be observed. Some benign lesions can enlarge in size to later cause problems, and require treatment though they are not cancerous. And malignant lesions should be treated by an experienced urologist.

I Was Diagnosed with a hyodense lesion on my right kidney. Is This Serious?

I Was Diagnosed with a hyodense lesion on my right kidney. Is This Serious?

Lesion right kidney: This finding requires further characterization. If this was an ultrasound finding, then the choice is to do no further testing, vs repeat ultrasound in 4-6 months, vs undergo MRI with Gadolinium. This may be a simple cyst. Harmless. It may be a complex cyst, which is uncertain until further characterized by MRI.

What does "kidney lesion most likely cyst but cannot definitively say since scan was unenhanced" mean?

What does "kidney lesion most likely cyst but cannot definitively say since scan was unenhanced" mean?

No contrast: A ct scan can be done with IV contrast, oral contrast, both or no contrast. The contrast that goes through the blood stream causes certain areas of our body to enhance while other solid areas may not. Differentiating between a solid tumor or mass from a benign cyst or a malignant appearing cystic tumor can be clarified by what areas enhance with contrast and which do not. Your study had none.

What test are needed for a kidney lesion to make sure it isn't cancer.

What test are needed for a kidney lesion to make sure it isn't cancer.

Depends: A radiologist may be able to certify it as benign based on images (benign cysts are extremely common), or may do some dye studies. You have a right to find out from your physician what's the appropriate workup for your mass, and whether biopsy or some other means of getting tissue is in order.

"Incidental low attenuation lesion" found in kidney. 7mm in size. What does "low attenuation" mean?

"Incidental low attenuation lesion" found in kidney. 7mm in size. What does "low attenuation" mean?

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.

Was told I have a cyst, or a lesion on my right kidney, I been having pains in that area, what should I do?

Was told I have a cyst, or a lesion on my right kidney, I been having pains in that area, what should I do?

Kidney: A simple cyst on the kidney is of no concern. A lesion could be any abnormal finding, including a cyst. The important distinction would be if the radiologist called it a mass. Discuss details with your doctor. You can get some blood and urine tests as well. Further imaging like a ct scan can also evaluate for stones and ureteral problems.

Diagnosed with low density lesion interpolar aspect left kidney, statistically beneign. Should I have this looked at for further evaluation?

Diagnosed with low density lesion interpolar aspect left kidney, statistically beneign. Should I have this looked at for further evaluation?

It depends: A Lesion in the kidney can be a benign cyst, which are common. But it can also be a solid lesion. Depending on your Age, the nature of the lesion, and its size will dictate further testing. But you should have a consultation with a doctor to examine you and guide you further.

MRI shows 6mm lesion on kidney and reads "may demonstrate minimal partial internal septation"? What is the significance of the word "minimal? "

MRI shows 6mm lesion on kidney and reads "may demonstrate minimal partial internal septation"? What is the significance of the word "minimal? "

Radiology hedge.: Renal cysts range from simple to complex. Simple cysts are common and are of no concern whatsoever (Grade 1). Complex cysts have solid regions which are usually an indicator of cancer (Grade 5). By using the word "minimal septation" the radiologist is giving the cyst a Grade 2, which is more likely benign than not. Chances are very good that this is nothing to worry about.

LT kidney normal size with no mass lesion, normal cortical thickness A mild to moderate stasis is seen in it Significant cortical thinning also seen7mm?

LT kidney normal size with no mass lesion, normal cortical thickness A mild to moderate stasis is seen in it Significant cortical thinning also seen7mm?

Here are some. ..: I wouldn't jump into the ship of overwhelming worry over this finding as described. Instead, make sure the finding is correlated with your clinical scenario over time to discern what could be the underlying cause if identifiable. On the other hand, the report may be a slight "normal" variation with no clinical significance at all. So, ask Doc for logical interpretation and follow-up before jumping

CT 1: 12 mos ago (6mm kidney lesion) CT2: 7 mos ago (6mm kidney lesion) MRI: 4 mos ago (6mm kidney lesion) May demonstrate minimal septation?

CT 1: 12 mos ago (6mm kidney lesion) CT2: 7 mos ago (6mm kidney lesion) MRI: 4 mos ago (6mm kidney lesion) May demonstrate minimal septation?

6mm renal lesion: Hello~ you have a STABLE SMALL renal mass. Anything under 4cm is considered small, and the smaller the more chance of it being benign. The commonest mass is a cyst. They are benign. Yours is "septate" so its solid. Solid masses > chance of malignancy. You should see a Nephrologist to follow this. But its probably benign thanks

The doctor said that my baby had a cystic lesion on her kidney. What does that mean?

The doctor said that my baby had a cystic lesion on her kidney. What does that mean?

Dr should explain: Baby could have one of many types of cystic lesions. Probably most common is so called multicystic kidney displasia, birth defect where part of, or entire kidney is made up of a bunch of cysts. Opposite kidney is usually normal and child will have a normal life. May have a simple cyst, may have a complex cyst which is usually benign. Can be an obstructed calyx or blocked part of duplex kidney. Ask dr.

I have a 9mm lesion in right kidney? Do I need to go see a doctor or will it heal itself?

I have a 9mm lesion in right kidney? Do I need to go see a doctor or will it heal itself?

What sort of lesion?: Is it a solid mass or a cystic one? Is it a stone? See your fp to review the imaging study report to get better understanding of lesion's nature. S/he can then describe a course of action. If you're having flank pain or blood in urine, definitely need to see doctor.

What is a low-density lesion medially in mid pole of kidney, most likely represent a cyst, can't be definitively characterized as study is unenhanced.

Probable cyst: Based on the test result but the radiologist is not sure. Strongly suggest an informed followup discussion with the doctor that ordered the test.

Need another scan for kidney then colonoscopy then surgery called da vinci surgery? I'm nervous says compex cystic lesion neoplasm cannot be excluded

Need another scan for kidney then colonoscopy then surgery called da vinci surgery? I'm nervous says compex cystic lesion neoplasm cannot be excluded

CT scan findings: You are being evaluated, aka "worked up" for the cystic mass. Surgery has been recommended. Being anxious during this time is normal. Risk/benefit analysis of your case with your surgery team. Open, laprascopic and robotic are techniques, how your surgeon performs your surgery. Robotic is newer but not necessarily better. Talk to your regular doc, possible second opinion, be well. Pathology.
