This is a preliminary study carried out on the adult population of the Sivas region. The aim was to determine the incidence of Cavum Septum Pellucidum (CSP), Cavum Vergae (CV) and Cavum Velum Interpositi (CVI) and to compare the results with the data of previous studies and the relevant literature. A total of 442 computed tomography (CT) scans (302 males, 140 females), in axial plane, from the archive of the Department of Neurosurgery at Cumhuriyet University were examined to find out the brain midline cavities. Among the 442 CT scans, 69 (15.61%) had these brain midline cavities. Out of these 69 cases, 20 (4.52%) were Cavum Septum Pellucidum (CSP), 12 (2.71%) were Cavum Vergae (CV), 32 (7.24%) had Cavum Velum Interpositi (CVI), 3 (0.68%) had Cavum Septum Pellucidum (CSP) with Cavum Vergae (CV) and 2 (0.46%) had Cavum Septum Pellucidum (CSP) with Cavum Velum Interpositi (CVI). In this prospective study, the incidences of CSP and CVI were lower but the incidence of CV was higher than in previous studies.
