Summary
Reversible posterior leukoencephalopathy syndrome (RPLS) can occur with eclampsia or hypertensive encephalopathy. Neuroimaging reveals characteristic edema, and MRI/MRA aid diagnosis and follow-up of brain edema and vasospasm in RPLS.
Area of Science:
- Neurology
- Radiology
- Obstetrics
Background:
- Reversible posterior leukoencephalopathy syndrome (RPLS) is a neurological condition often associated with eclampsia, hypertensive encephalopathy, or immunosuppression.
- Understanding the neuroimaging characteristics and diagnostic tools for RPLS is crucial for timely intervention.
Observation:
- Three cases of RPLS are presented, occurring in patients with eclampsia or hypertensive encephalopathy.
- Neuroimaging findings included subcortical edema without infarction, with specific MRI FLAIR sequences showing bilateral temporal and occipital lobe hyperintensities.
- MR angiography (MRA) demonstrated intracranial vasospasm, which resolved with treatment and time.
Findings:
- MRI and MRA are valuable noninvasive tools for diagnosing brain edema and vasospasm in RPLS.
- Characteristic findings include subcortical edema on MRI and intracranial vasospasm on MRA.
- Follow-up imaging confirmed the resolution of vasospasm and residual edema.
Implications:
- Early diagnosis and monitoring of RPLS using MRI and MRA can improve patient outcomes.
- These imaging modalities provide complementary information for assessing brain edema and vasospasm.
- Further research into the pathophysiology and management of RPLS associated with hypertensive disorders is warranted.
