Learning objectives
After reviewing this exhibit,
you should be able to determine:
1.
proper work up of patients with suspected TB,
including laboratory and pathologic findings
2.
the common and uncommon plain film / conventional and CT imaging findings in patients with thoracic Tuberculosis (TB)
3.
findings in immuno-compromised patients
4.
findings on molecular imaging,
such as PET-CT
Sections on atypical mycobacteria,
TB in HIV + patients,
and treatment guidelines are also included at the end of this exhibit.
Background
Tuberculosis has been a nemesis for centuries.
It is thought to be spread via airborne contamination and inhalation.
Imaging has added to the rapidity of diagnosis.
In the HIV era there are new imaging findings to be aware of.
We will review these as notable on conventional imaging,
including CT as well as PET-CT findings.
Radiologists should also be aware of pathology and laboratory findings in patients with TB.
Treatment is also altered when immune-compromise is present.
Imaging findings OR Procedure details
The imaging findings for thoracic TB are extensive.
We will review selected examples of these in light of patient history and the main differential diagnostic considerations.
Many Radiologists might not be aware of the range of TB findings on PET-CT,
so these will be emphasized.
What follows are the slides for the entire exhibit as embedded jpg files.
Conclusion
By knowing the patterns of primary and post - primary TB in a variety of clinical settings,
the Radiologist can often be a good diagnostician,
even without a stethescope or sputum sample.
TB can also be present on PET-CT,
so Radiologists also need to be aware of such findings.
The differential diagnosis,
in light of clinical history,
will often help steer the clinician to the correct diagnosis.
The authors thank you for reviewing our exhibit.
