- MRI: IgG4-related orbital involvement
- Limitation
- Signal intensity cannot be compared across different sequences.
Definition
Imaging of a documented inflammatory orbital process.
Examination or reading method
Identify planes, sequences and arrowed structures.
Morphological description
Arrows mark muscular and lacrimal abnormalities.
Context and interpretation
The source concludes IgG4-related orbitopathy.
Differential diagnoses
MRI alone cannot distinguish every inflammation from tumour.
Associated findings
Correlate ocular signs and histology.
Red flags
Assess visual impact.
Pitfalls and limitations
Signal intensity cannot be compared across different sequences.
Take-home message
Describe structures before naming the disease.
