Practice Guideline GuidelineClinical guidelines for idiopathic normal pressure hydrocephalus.
Idiopathic normal pressure hydrocephalus (iNPH) is a syndrome characterized by gait disturbance, dementia, and/or urinary incontinence without causative disorders, and ventricular enlargement due to disturbance of the cerebrospinal fluid (SF) circulation. The number of patients with iNPH will increase with the aging of the population in Japan. However, iNPH is often difficult to differentiate from other senile disorders such as lumbar canal stenosis, parkinsonism, and so on. ⋯ The CSF tap test is a major diagnostic measure because of the simplicity and less invasiveness. Use of the programmable valve is recommended to decrease CSF overdrainage. These guidelines are helpful for the diagnosis and treatment of iNPH.

ReviewAssociation of paranasal sinus osteoma and intracranial mucocele--two case reports.
Two young adult males presented with paranasal sinus osteoma associated with mucocele. A 20-year-old man presented with headache and seizure, and another 20-year-old man presented with headache, frontal deformity, and visual disturbances. ⋯ The higher aggressiveness of the lesions may be due to the presence of the mucocele. Calcification and ossification of the mucocele probably contributes to the unexpected enlargement of the osteoma.
