Observations:
This case report describes a 75 year-old Caucasian male who initially presented with persistent daily headaches. Physical exam elicited multiple cranial nerve palsies. Gadolinium-enhanced brain MRI demonstrated pachymeningitis. Labs revealed elevated proteinase-3 antineutrophil cytoplasmic antibodies (PR3-ANCA) and cytoplasmic antineutrophil cytoplasmic antibodies (c-ANCA), confirming a diagnosis of GPA.
Conclusion:
GPA should be considered in older patients presenting with persistent daily headaches and pachymeningitis. Contrast-enhanced brain MRI is an important diagnostic tool.
Insights
Granulomatosis with polyangiitis (GPA) can cause persistent headaches and cranial nerve palsies in older adults. Early diagnosis via MRI and ANCA testing is crucial for effective treatment.
Area of Science:
- Neurology
- Rheumatology
- Immunology
Background:
- Granulomatosis with polyangiitis (GPA) is a rare autoimmune vasculitis.
- It commonly affects the respiratory tract and kidneys, but can involve the central nervous system.
Observation:
- A 75-year-old male presented with daily headaches and multiple cranial nerve palsies.
- Brain MRI revealed pachymeningitis, inflammation of the dura mater.
Findings:
- Laboratory tests showed elevated proteinase-3 antineutrophil cytoplasmic antibodies (PR3-ANCA) and cytoplasmic antineutrophil cytoplasmic antibodies (c-ANCA).
- These findings confirmed the diagnosis of GPA.
Implications:
- GPA should be considered in the differential diagnosis of persistent headaches and pachymeningitis in elderly patients.
- Contrast-enhanced brain MRI is a valuable tool for diagnosing CNS involvement in GPA.
