Which is the correct
Diagnosis?
-
Sarcoidosis
-
Rheumatoid Arthritis
-
Hypersensitivity Pneumonitis
-
IPF
Correct!
![Correct Correct](/us/insights-in-ild/themes/custom/ild/img/logo1.png)
Hypersensitivity Pneumonitis
This is correct!
Incorrect!
![Incorrect X Clipart Incorrect X Clipart](/us/insights-in-ild/themes/custom/ild/img/test-your-eyes-q1-answer-img1.png)
Idiopathic Pulmonary Fibrosis
While the smoking history and age are consistent with an lPF diagnosis, the upper lung process in HRCT is inconsistent with UIP/IPF.
Incorrect!
![Incorrect X Clipart Incorrect X Clipart](/us/insights-in-ild/themes/custom/ild/img/test-your-eyes-q1-answer-img1.png)
Rheumatoid Arthritis
The patient had negative CCP and RF antibodies, both of which are associated with rheumatoid arthritis. Further, the patient had no joint involvement or other signs and symptoms of rheumatoid arthritis.
Incorrect!

Sarcoidosis
While the HRCT indicates upper-lung process, the fibrotic pattern is not typical of sarcoidosis, in which nodules and/or conglomerate masses are evident. Furthermore, there are no nodular lesions in SLB.
