Brief Answer:
MRI with contrast is better than CT scan(contrast) is suspected carcinoma.

Detailed Answer:
Hello,
Thanks for writing to HCM,
I've gone through your query and understand your concern,

MRI with contrast is better than contrast CT scan in suspected carcinoma.
CT is better in evaluating lesions containing calcifications.

But MRI is not widely used because it takes more time and it need patient co-operation for image quality.
MRI is also useful in morphological and functional assessment of kidneys in children.

In your case, I suggest for MRI as there is a doubtful small cystic lesion.

Get well soon.

Hope I have answered your query.
Further queries are most welcome.

Have you observed my test results?

What does the term "malignant in nature" mean?
Does it have the meaning that it could currently be benign, with the probability of becoming a cancer?

Also, please define small solid neoplasm.

Please attach full reports.

Malignant means it may be cancerous.

Some benign lesions in our body may become malignant.Conversion of benign into malignant depend upon many things like organ involved,type of lesion etc.

Neoplasm(Cancer)may be both solid,cystic(fluid containing) or mixed(both solid and cystic).

What is the probability of a 1.5 cm solid neoplasm located in the medial area of the kidney being benign?

Can size dictate whether a solid neoplasm is benign or cancerous?

I have heard that the smaller the size of a kidney mass increases the probability of it being benign.

In terms of Houndsfell Units for enhancement on a ct, does any number dictate benign or cancerous?

Brief Answer:
Size of tumour is not a criteria for benign or malignant lesions.

Detailed Answer:
Hello,
Thanks for writing to HCM,
I've gone through your query and understand your concern,

Size of tumour is not a criteria for benign or malignant lesions.
Malignant lesions may be small also.
Exact nature can only be assessed by biopsy.

Solid tumour may be both benign or malignant.We have to see enhancement pattern.Contrast enhancement is more in favour of malignancy.

Solid tumour may also be a developmental aberration and it may mimic tumour. Enhancement pattern in terms of H.U of such lesions are same as normal kidney tissue.
Whereas malignant tumour cells may enhance differently(may be 20-30 H.U more than tumour cells.

As far as an enhancement pattern that goes from 29 HU to 57 HU enhanced, then delayed enhancement to 44 HU. Could this favor a possible benign solid tumor as well. Would something like this need a biopsy to confirm one way or another?

On small tumors less than 2 cm, if you fully remove the kidney, do you consider that issued cured. Also, what is the odds of recurrence using this method?

Thanks for all the information.

Brief Answer:
Enhancement may indicate malignancy but only biopsy is confirmatory.

Detailed Answer:
Hello,
Thanks for writing to HCM,
I've gone through your query and understand your concern,

Enhancement may indicate malignancy but only biopsy is confirmatory.

Findings may indicate stage 1 kidney cancer and total nephrectomy(total removal of kidney) is not done for this condition.
Partial nephrectomy may be advised.

Does enhancement always indicate malignancy or even though there is enhancement could they be benign?
doctor
Answered by Dr. Indu Kumar (13 minutes later)
Brief Answer:
Enhancement is not confirmatory for malignancy.

Detailed Answer:
Hello,
Thanks for writing to HCM,
I've gone through your query and understand your concern,

Enhancement is not confirmatory for malignancy and it doesn't always confirm malignancy.It is just a indicative sign and only biopsy/FNAC is confirmatory.

It is possible to see enhancement, and after biopsy it is found to be benign.

In other words, even though a spot is enhanced on a ct, is it still possible that it can be benign after biopsy?

Just so I understand, there is evidence to suggest that even though there is enhancement on a ct scan, that mass or lesion can be found benign after biopsy?
