Microscopic angiitis can rarely affect the brain and muscles, causing symptoms like mononeuritis multiplex and stroke. Early diagnosis and treatment are crucial for managing this rare vasculitis.
Area of Science:
- Neurology
- Rheumatology
- Pathology
Background:
- Peripheral neuropathy is a common complication of microscopic angiitis.
- Central nervous system and muscle involvement are rare but serious manifestations.
Observation:
- A 48-year-old man presented with mononeuritis multiplex, progressing to coma and cerebral hemorrhage.
- Laboratory tests showed inflammation, kidney dysfunction, and positive myeloperoxidase-antineutrophil cytoplasmic antibodies.
Findings:
- Neuromuscular biopsy confirmed small-vessel vasculitis (microscopic angiitis) with myositis and axonal loss.
- The patient experienced a massive cerebral hematoma leading to hemiplegia.
Implications:
- Microscopic angiitis should be considered in differential diagnoses for myositis and intracerebral hemorrhage.
- Prompt surgical intervention and immunosuppressive therapy led to a good outcome.
- Highlights the importance of considering rare neurological and muscular manifestations of vasculitis.
