A Case of Eosinophilic Meningitis Associated with Idiopathic Hypereosinophilic Syndrome

Idiopathic hypereosinophilic syndrome (IHES) is a rare disease characterized by peripheral blood eosinophilia and eosinophilic infiltration of multiple organs, including the nervous system. The neurologic manifestations in hypereosinophilic syndrome are variable, but eosinophilic meningitis as a manifestation has not been well documented in IHES. We report a case of eosinophilic meningitis associated with IHES, which showed a good response to steroid treatment.

18F-FDG PET and 99mTc-ECD SPECT between Ictal and Interictal Phase in a Patient with Status Epilepticus Arising from the Occipital Lobe

A 35-year-old woman suffered from elementary visual symptom that was confirmed as nonconvulsive simple partial status epilepticus arising from the right occipital lobe. 99mTc-ECD SPECT and 18F-FDG PET were done during the ictal and interictal phase, respectively, which were documented by EEG. Subtraction images of SPECT and PET were overlayed on the MRI by SISCOM to compare the area of metabolic change with that of perfusion change. There was no definite mismatch between the hypermetabolic area and the hyperperfusion area during nonconvulsive status epilepticus.
