title: [A study of incidence and symptoms in 71 patients with cavum septi pellucidi].
abstract: Seventy one patients with cavum septi pellucidi (CSP) were found among 2722 patients who had received computerized tomographic scanning. A clinical evaluation of these patients was made to examine incidence, clinical symptoms and neurological signs of CSP. The results obtained were as follows: 1) Incidence of CSP was 2.6% of the patients who visited outpatient clinic of a mental hospital. Sex ratio was M:F 1.9:1.0. 2) Age of onset of chief complaints mainly ranged from 10 to 30 years in male, and 10 to 60 years in female. 3) Complications of epileptic attacks and mental retardation were 22.5% and 9.9% of the patients with CSP, respectively. Frequency of these complications was significantly higher, as compared with the patients without CSP. 4) Chief complaints of the patients with CSP were; headache (43.1%), nausea and/or vomiting (23.8%), epileptic attacks (22.5%), dizziness (19.7%) and emotional instability (19.7%). 5) No neurological signs specific to CSP was found in this study. 6) EEG abnormality was found in 22 of 71 patients with CSP.
