Abstract:
In a patient with acute posterior multifocal placoid pigment epitheliopathy (APMPPE), a pontine infarction occurred about 6 months after the ophthalmological manifestation. We report the first case with histopathologically proven vasculitis shown by muscle biopsy and the first positron emission tomographic documentation in APMPPE. The ophthalmological and cerebral symptoms responded well to steroid treatment. Long-term immunosuppression (e.g. azathioprine 1-2 mg/kg) seems to decrease the risk of recurrent systemic vasculitis.
Insights
Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) can lead to pontine infarction. This case highlights histopathologically proven vasculitis and successful steroid treatment for APMPPE symptoms.
Area of Science:
- Ophthalmology
- Neurology
- Rheumatology
Background:
- Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) is an inflammatory condition affecting the eye.
- Cerebral involvement in APMPPE is rare, with limited histopathological evidence.
Observation:
- A patient with APMPPE developed a pontine infarction six months after initial ophthalmological symptoms.
- The patient underwent muscle biopsy, revealing histopathologically confirmed vasculitis.
- Positron emission tomography (PET) was used for documentation, a first in APMPPE cases.
Findings:
- Both ophthalmological and neurological symptoms showed a positive response to corticosteroid therapy.
- Long-term immunosuppressive therapy, such as azathioprine, appeared to reduce the recurrence of systemic vasculitis.
Implications:
- This case provides crucial histopathological evidence linking APMPPE to systemic vasculitis.
- The findings suggest that early and aggressive immunosuppression may be vital in managing APMPPE and preventing severe neurological complications.
- This study underscores the importance of a multidisciplinary approach in diagnosing and treating APMPPE with potential systemic manifestations.
