Purpose: To assess the relation of cavum septi pellucidi (CSP) to other brain abnormalities and correlate this to its size and form of presentation.
Methods: We reviewed the neuroimaging studies of 1840 patients in our cross sectional study. A CSP was found in 85 (4.6%) of these patients. We graded CSP into three grades: I<1 cm3, II 1-2 cm3, III>2 cm3.
Results: Headache was the main presenting symptom in 44.7% of our patient’s sample. Patients less than 20 years old tend to have grade I CSP while grades II and III occurred more in patients older than 20. Sixty-seven percent of patients with grade I show no associated brain abnormality. There is no significant predominance of one sex over the other to have CSP.
Conclusion: Most of grade I patients show no other abnormality while most of patients with grades II and III show other abnormalities in their brain imaging.
