Thoughts on these CT Findings


Recommended Posts


Hi- I'm new to this gruop, and would love to hear someones opinions on the below CT scan report from the radiologist.  

I have a bronchoscope scheduled for Friday and Pulminologist said she would have results for me, likely late next week.

41 year old non-smoker male.  


CT CHEST WITHOUT CONTRAST dated 4/20/2022 9:07 AM

CLINICAL HISTORY: Cough, persistent.

COMPARISON: Chest x-ray 3/29/2022.

PROCEDURE COMMENTS: CT of the chest was performed without IV contrast. This
examination was performed with automated exposure control to minimize patient
radiation exposure.


Lungs: The right lower lobar bronchus, at the level of the superior segmental
bronchus, contains an endobronchial lesion with subsequent peripheral mucous
plugging and basal segmental atelectasis. Small regions of tree-in-bud
inflammatory infiltrate are also seen through the superior segment of the right
lower lobe.

Posterior left lower lobe pulmonary nodule, 3 mm, series 3 image 78. No other
pulmonary nodules, focal airspace consolidations or masses. No pleural effusions
or pneumothorax. The central airways are patent.

Lymph nodes: Noncontrast technique limits evaluation for hilar lymphadenopathy.
Within these constraints, no supraclavicular, axillary, mediastinal, or hilar
lymphadenopathy is identified.

Mediastinum: The heart size is within normal limits. No pericardial effusion.
Small air-fluid level in the distal thoracic esophagus.

Chest wall and spine: No acute osseous abnormality.

Upper abdomen: The upper abdominal viscera are unremarkable.

1. The right lower lobar bronchus is occluded by an endobronchial lesion.
Further evaluation with endobronchial/bronchoscopic tissue sampling is advised.
The age of the patient and the endobronchial location raises the possibility of
pulmonary carcinoid.

2. The right lower lobe basal segments demonstrate atelectasis with scattered
tree-in-bud inflammatory infiltrates through the superior segment of the right
lower lobe.

3. No definite lymphadenopathy of the chest.

4. The small, 3 mm, left lower lobe pulmonary nodule should remain under
longer-term follow-up. To be based upon the patient's subsequent oncological

Welcome here.

I'm certainly not a doctor but the operative words in the CT report are in paragraph 1 of the Impression: "pulmonary carcinoid." Here is an explanation of what a pulmonary carcinoid is. So you have a tumor (lesion) in the right lower lobar bronchus. Is it metastatic lung cancer? The radiologist suggests your age and location of the lesion raises that possibility but it remains a possibility until a biopsy is performed.

Unfortunately, for more information, you'll need to wait for the results of your bronchoscopy. I hope it is something other than lung cancer.

Stay the course.

Thank you Tom!

I know I'm reading tea leaves at this point, and mid-late next week I'm supposed to have a diagnosis, so it's almost certainly not worth the effort/stress... but wanted to get some feedback other then from the google... and have been really impressed with some of the other threads and the feedback I've read through today.

I had my consult with the pulminologist this morning and left with a few pretty strong curiosities at this point...

how does a radioligist suspect something that rare (Lung carcinoid) over something that is 20X or so more common (NSCLC)? 

Do initial CT scans of chest, lymph nodes etc - have a relatively good track record of being predictive of finding spread as well as locating the primary tumor, or not really and the PET scan later often finds significant spreading the CT doesn't show in regards to lymph node or other distant areas?

Thanks so much again, it is extremely appreciated!

Do initial CT scans have a relatively good track record of predicting lung cancer or finding a primary tumor? I certainly can't offer a definitive answer. In cases like my initial diagnosis with a very large tumor blocking my main stem bronchus, then yes. There is also ambiguity with the PET scan. Here is my explanation on PET findings. Unfortunately, the only definitive way to make a positive lung cancer diagnosis is with a tissue biopsy. The pathologist looks at the tissue sample under a microscope (histology exam) and notes the characteristic shape and size of lung cancer cells. Then, for most folks these days, the sample is sent for further laboratory biomarker testing

Primary tumors sometimes are hard to find but if your biopsy shows non small cell, small cell or large cell lung cancer, you should undergo treatment.

I wouldn't know how your radiologist determined your rare lesion (lung carcinoid). I know all this is unsettling; I've been down the "scanziety" path many times in my treatment history. One does not cope but hope springs eternal.

Stay the course.

Results came back late today from bronchoscopy... though they are negative (yeah!) they are also very "bland" according to my pulmonologist and require more study.  She has requested a PET scan to be done asap... This roller coaster ride is absolutely insane... and I have this terrible suspicion I can't shake, that it is only getting started.

Does anyone have any insight or thoughts on the pathology report, or of bronchoscopys missing stuff found on PET scans?


Collected Date: 4/29/2022 14:21 PDT Case Number: SM-22-0001416
Surgical Pathology Report
Diagnosis After Microscopic Examination:
Lung mass, right lower lobe, biopsies:
- Fragments of benign fibrotic/sclerotic tissue with patchy areas of calcification.
- AFB and GMS stains negative for acid fast and fungal organisms .
- Negative for malignancy.
- See comment.

Dr. D. Glidden has reviewed this case and concurs with the diagnosis.
The submitted material consists of nodular fragments of densely fibrotic/sclerotic tissue,
have patchy areas of calcification. There is no overt cytologic atypia within the submitted
material and no immunohistochemical evidence of malignancy.
However, sampling issues must be considered, especially on small biopsy specimens, as an
underlying lesion or process may not be represented within the submitted material. If
high clinical suspicion exists, submission of additional materials is recommended. Clinical
correlation required. See pathology report CP-22-1521 for complete cytology evaluation.
The following immunohistochemical and special stains were performed with adequate controls.
Pooled cytokeratin staining highlights the rare benign bronchial epithelial cells and shows
nonspecific staining within scattered histiocytes. CD68 staining highlights the admixed
histiocytes within the fibrotic regions. Cytokeratin 7 and TTF1 stains highlight the benign
bronchial elements. These elements also show small subset positivity with CK5/6 and p63.
Synaptophysin and chromogranin staining is negative. There is no immunohistochemical evidence
of malignancy within the submitted material. AFP and GMS stains are negative for acid fast and
fungal organisms. Congo red staining is performed and is negative for amyloid deposition.
(Analyte specific reagents are used in many laboratory tests necessary for standard medical
care and generally do not require FDA approval. This test was developed, and its performance
characteristics determined by Legacy Laboratories. It has not been cleared or approved by the
U.S. Food and Drug Administration.)

I think the most important words on your report are "negative for malignancy". The disclaimer-like words added with Dr. Glidden's review don't add anything concerning to me. Of course, the biopsy sample is the only thing this report attends to and there could be other malignant areas. But that is always the case.

Often with our disease we don't get definitive results or conclusive reports. If you feel that is the case, then ask your doctor to enroll you in a time-phased screening program where a CT scan is administered say once per quarter and changes can be tracked over time.

As to the results on this report, negative for malignancy is a wonderful outcome in our community.

Stay the course.

What a PET scan will do is give your docs more information. Right now, from the biopsy they have, they can't see stuff that indicates cancer, but they also can't see (via the biopsy) what else might be happening. This explains exactly what a PET scan is and how it fits into a diagnostic process. "PET" is short for "positron emission tomography", so when you get to the page, look for the subheading that says Positron Emission Tomography (PET).

Unfortunately for all of us, there's not one test that says whether you do or don't have cancer. Right now you're in the agonizing part, where your docs are collecting data. Once they have a lot, they sit down and see if and how it all works together.

Try not to torture yourself-- each test gives only one piece of the puzzle. Sometimes, the same test will give two pieces of information, one of which might say, "No cancer" and the other, which might say, "Hey, this is kinda weird. Let's get more data." So every time you get a test, you need to see it as just one more piece of the puzzle, until your doc says, "OK, what I think you have is XYZ and here's why I think that."

One step at a time, my friend. It is really hard, but it's the only way. I like that you say "I need to take good news for today and continue on." Yep. Find the goodness in each moment and celebrate that.

Thank you both for the thoughts and information.

I was able to get in for my PET scan on Friday.  The results were worrisome, but not definitive for a localized malignancy where the tumor is located.  No sign of spread to any other areas...

My initial thought when receiving this info Friday was to want to have surgery as soon as possible to remove whatever it is.  My pulmologist has instead referred me to a specialist pulmonologist who wants to remove the tumor using a rigid bronchoscope and laser.

I am meeting with him this afternoon at 4 PM to get more information about the procedure, which they would like to schedule for Tuesday or Wednesday of next week.  In his words, a thoracic surgeon would almost certainly not agree to perform a lobectomy without a formal cancer diagnosis, and by removing this with the bronchoscopic procedure it will have the following benefits:

#1- they can do it much sooner then they could schedule a VATS surgery (which the scheduling process is likely not even possible to get rolling without further diagnostic tests)

#2- it has a very good chance of fairly immediately fixing the current symptoms in my lung from the blocked airway (atelectasis, inflammation in airways)

#3- it is also definitively diagnostic as they can take samples from the growth after removal... in certain scenarios, where those are found to be benign, it would also likely be curative, leaving lungs in tact...

Are there any questions or concerns that this group thinks I should ask at the consult this afternoon?  I'm not particularly scared of the procedure itself... I do worry it is likely the lead up to a VATS surgery, that to me in a lot of ways I'd rather just do that and skip this step.

Slow down, my friend. You seem to have already decided that you're going to end up with VATS surgery to remove part of your lung. That's not what I'm hearing your doc saying is necessary-- HOORAY! There's no definitive cancer diagnosis-- HOORAY! 

The benefit of doing this bronch-approach is that it's not anywhere near the big deal that a lobectomy would be. I imagine it would actually be performed on an outpatient basis.

Then they could biopsy the dickens out of it. If it were to be cancer, you'd have at least gotten the big badness out of there, thereby minimizing the potential for spread. If it's not cancer, you'd have gotten the badness out and be able to learn what might be next treatment-wise, which may be nothing. 

Learning is great-- unless you are learning enough to leap to conclusions that may really have nothing to do with you. That's why you see so many cautions about avoiding Dr. Google. Take deep breaths and do a little flexing of that patience muscle. Waiting is the worst. But sometimes that's where we are....

Hang in.

Thanks for your thoughts much appreciated!

The consult went well yesterday, and I do like the interventional pulmonologist that I’ve been referred to. 

The uptake on the PET throughout the area of the tumor is 9.75.  I know without a biopsy confirming, it is not a “cancer diagnosis”, but it’s an endobronchial tumor completely blocking an airway with a GFU uptake that very strongly suggests cancer. It seems to me that we are trying to determine the type of cancer at this point, not if…

The most common treatment for a localized lung tumor blocking an airway, whether benign or cancerous, is a lobectomy… but the location of it is such that it is a fairly complex surgery- would require a sleeve resection and possibly 2 lobes removed… 

My pulmonologist believes if it is a carcinoid tumor he can treat it entirely through broncoscopic procedures- 2 more bronchoscopic procedures after this one next week.  If it’s an atypical carcinoid or something else more aggressive- this procedure has no negative impact on vats surgery or radiation treatments that would follow.  If it’s benign the surgery next week could be curative and monitoring would be all that’s required. 

Im doing pretty well so far this week and have found peace with this course.  I like having a plan… next Tuesday is the procedure, before next weekend I’ll have a definitive diagnosis, and next steps will go from there. The uncertainty the last 4 weeks has been the hardest thing I’ve dealt with. I’m a 41 year old widow with boys 10, 8, and 3.  The idea of leaving them alone is more then I am capable of truly processing.  

Thank you to this forum and everyone’s feedback. I have my fingers and toes crossed for next week and genuinely appreciate every story I’ve read on here and every person who helps others through this horrifying process. 

much love ❤️
