Fundoscopy showed bilateral papilledema [Figure 1].
Pre- and post-surgical cavum septum pellucidum (CSP) and cavum vergae (CV). (a and b) show the CSP and CV on presurgical magnetic resonance imaging. (b) shows the septate cyst. (c) it is not possible to see the cyst on presurgical sagittal plane. (d and e), from the postsurgical CT, demonstrate the cyst in smaller volume. (f) it is not possible to see the cyst on postsurgical sagittal plane.

Cranial magnetic resonance imaging (MRI) demonstrated a CSP and CV cyst measuring 2.5 cm x 2.8 cm x 6.3 cm (longitudinal x transverse x anteroposterior) and an estimated volume of 22.93 cm3, which was causing bilateral obstruction of the foramen of Monro and consequent hydrocephalus [Figures 2a-c]. On postsurgical CT scan, the cyst was smaller and there were no bleeding or other significant abnormalities [Figures 2d-f].
