Hello, doctor.
Recently, after completing chemotherapy, I was hospitalized for surgery.
Before my admission, I underwent routine pre-admission tests, including a chest X-ray, blood tests, and an electrocardiogram.
I would like to ask about my chest X-ray report, specifically the term "Bilateral sharp costophrenic angles." My attending physician did not provide further explanation.
Thank you.
EXAMINATION: Chest: PA View (Standing).
FINDINGS: Normal heart size.
Placement of a right port-A catheter.
No definite active lung lesion.
Bilateral sharp costophrenic angles.

Dear Becca: Bilateral sharp costophrenic angles essentially indicate that the angles between the diaphragm and the rib cage on both sides are sharper than usual, which is not a concern.
If there are additional findings, there could be a possibility of pleural effusion.
Currently, there is no need to worry.
Changhua Hospital cares about you.

More Info


The term "bilateral sharp costophrenic angles" in your chest X-ray report refers to the appearance of the angles formed between the diaphragm and the ribs on both sides of your chest. In a normal chest X-ray, these angles should appear sharp and well-defined, indicating that there is no fluid accumulation or other abnormalities in the pleural space, which is the area between the lungs and the chest wall.


Understanding Costophrenic Angles
1. Anatomy: The costophrenic angles are located at the junction where the diaphragm meets the ribs. They are important landmarks in chest imaging. A sharp angle suggests that the pleural space is free of excess fluid (pleural effusion) or other pathological conditions.

2. Clinical Significance: The presence of sharp costophrenic angles is generally a positive finding. It indicates that there is no significant fluid accumulation, which can occur in conditions such as heart failure, pneumonia, or malignancy. In your case, the report states "no definite active lung lesion," which further supports that your lungs appear healthy and that there are no immediate concerns.

3. Normal Findings: In a normal chest X-ray, the costophrenic angles should be acute (less than 90 degrees). If they appear blunted or rounded, it could indicate the presence of fluid or other issues, such as pleural effusion or other pathological processes.


Context of Your Situation
Given that you recently underwent chemotherapy and are in a follow-up phase, it is understandable to be concerned about any findings in your medical reports. However, the mention of "bilateral sharp costophrenic angles" is reassuring. It suggests that your lungs are clear and that there are no signs of complications such as pleural effusion, which can sometimes occur after chemotherapy or surgery.


Additional Considerations
- Follow-Up: It is always a good practice to follow up with your healthcare provider regarding any findings in your medical reports. If you have any symptoms such as shortness of breath, chest pain, or persistent cough, make sure to discuss these with your doctor.


- Monitoring: Since you are recovering from chemotherapy, regular monitoring through imaging and clinical evaluations is essential. Your healthcare team will likely continue to assess your lung health and overall recovery.

- Understanding Imaging Reports: If you ever find yourself confused about medical terminology in your reports, don't hesitate to ask your healthcare provider for clarification. They can provide context and explain the significance of the findings in relation to your overall health.

In summary, "bilateral sharp costophrenic angles" is a favorable finding in your chest X-ray report, indicating that your pleural spaces are clear of fluid and that your lung health appears stable at this time. Always keep an open line of communication with your healthcare team to address any concerns or questions you may have as you continue your recovery process.
