Obstructive hydrocephalus caused by intraventricular collapse of malacoticbrain - Case report

The authors present the case of a 68-year-old man who experienced acute obs tructive hydrocephalus after having suffered an infarction in the occipital lobe. Histopathological and serial neuroimaging examinations revealed that portions of a large disintegrating occipital infarct had entered the later al ventricle and obstructed the passage of cerebrospinal fluid (CSF). Ventr icular drainage was performed for 2 weeks until the patient's hydrocephalus resolved. The CSF initially contained a high concentration of protein (107 0 mg/dl), a high leukocyte count of 115 cells/mm(3), and a rich fibrinous e xudate. Findings in the present case indicate that collapse of a periventricular is chemic lesion into the ventricles may sometimes occur not only after cerebr al hemorrhage but also after cerebral infarction.
