We report on magnetic resonance imaging (MRI) findings of eosinophilic meningoencephalitis caused by angiostrongyliasis in a 79-year-old Chinese woman. MR imaging in this case was compatible with the features of meningitis and angiostrongyliasis, including leptomeningeal thickening and microcavity formation with slight hemorrhagic and granulomatous inflammatory reaction caused by migration of worms. To our knowledge, this is the first report of MRI of eosinophilic meningoencephalitis caused by angiostrongyliasis in Taiwan.
