[A case of idiopathic hypereosinophilic syndrome with special reference to mental disorders and brain images].
We reported a case of idiopathic hypereosinophilic syndrome with psychiatric symptoms and abnormal areas in subcortical white matter on brain MRI. The 25-year-old man was referred to us because of fever, confusional state and emotional incontinence. He soon became apathetic and emotionless. While he was confused, we studied brain CT twice and brain MRI four times. In deep white matter around the lateral ventricles and the cortices of parietal lobe, occipital lobe and cerebellar hemispheres, T1-weighted MRI revealed low intensity areas and T2-weighted MRI showed high intensity areas. After gadolinium infusion, some above-stated areas were enhanced. The lesions in the deep white matter disappeared when symptoms diminished, while lesions in the occipital cortex remained unchanged. Brain MRI studies were beneficial and useful to analyse the rare idiopathic hypereosinophilic syndrome with psychic disorders.
