Insights
This pictorial essay highlights rare non-atherosclerotic coronary artery encasement causes like lymphoma and IgG4-related disease. Recognizing these conditions aids early diagnosis and treatment.
Area of Science:
- Cardiology
- Oncology
- Rheumatology
Background:
- Coronary artery encasement is typically associated with atherosclerosis.
- Non-atherosclerotic causes are uncommon but important to recognize.
Purpose of the Study:
- To present cases of non-atherosclerotic coronary artery encasement.
- To review the diagnostic features of these rare conditions.
Main Methods:
- Pictorial essay format.
- Presentation of institutional cases.
- Review of ancillary findings.
Main Results:
- Cases included malignant lymphoma, Erdheim-Chester disease, immunoglobulin G4 (IgG4)-related disease, and Polyarteritis Nodosa.
- Multisystemic involvement is a key diagnostic clue.
- Radiological and pathological findings were discussed.
Conclusions:
- Awareness of these uncommon disorders is crucial for accurate diagnosis.
- Early identification facilitates appropriate management.
- Multisystemic involvement aids in differentiating from atherosclerotic disease.
Abstract:
This pictorial essay presents cases of non-atherosclerotic coronary artery encasement which were encountered in our institution, including malignant lymphoma, Erdheim-Chester disease, immunoglobulin G4 (IgG4)-related disease and Polyarteritis Nodosa. These conditions usually have multisystemic involvement which aid in the diagnosis. Awareness of these uncommon disorders and their ancillary findings can facilitate early, accurate diagnosis and appropriate management.
