Caval variations of the septum pellucidum in A North-Central Nigerian population: A retrospective computed tomographic study

Background: The septum pellucidum (SP) and its cystic variations are occasionally seen as midline structures during computed tomography (CT) brain investigation of individuals. There is no documented evidence of the pattern and frequency of caval variations of the SP in our environment. Aim: The aim of this study is to determine the prevalence of caval variations of the SP in a North-Central Nigerian population using CT scan. Materials and Methods: This retrospective study evaluated the presence of the caval variations on CT brain scans acquired between January 2011 and January 2013 in a tertiary hospital in North Central Nigeria. Data analysis was carried out using SPSS version 16. A value of P
