  • Title: Obstructive hydrocephalus caused by intraventricular collapse of malacotic brain. Case report.
    Author: Nakaguchi H, Miyamoto M.
    Journal: J Neurosurg; 2001 Jul; 95(1):119-21. PubMed ID: 11453380.
    Abstract:
    The authors present the case of a 68-year-old man who experienced acute obstructive 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 lateral ventricle and obstructed the passage of cerebrospinal fluid (CSF). Ventricular drainage was performed for 2 weeks until the patient's hydrocephalus resolved. The CSF initially contained a high concentration of protein (1070 mg/dl), a high leukocyte count of 115 cells/mm3, and a rich fibrinous exudate. Findings in the present case indicate that collapse of a periventricular ischemic lesion into the ventricles may sometimes occur not only after cerebral hemorrhage but also after cerebral infarction.
