A pineal cyst (PC) is a benign affection of the pineal gland, its prevalence in population reaches 1-2 %. Etiopathogenesis of PC is unknown, several hypotheses have been proposed. One of the hypothesis consider perinatal hypoxia as a causative factor for a development of PC in later life. Ozmen et al. showed significantly higher prevalence of PC in patients with cerebral palsy (p<0.001). Bregant et al. studied presence of PC in patients that suffered from a mild to moderate perinatal hypoxia. Prevalence of PC reached 36 % in these patients and presence of PC was associated with a atrophy of the corpus callosum (p<0.005). The atrophy of the corpus callosum is considered to be a sign of a periventricular leukomalacia, i.e. an ischemic insult in a perinatal period.~In the present study, we are going to compare an area of corpus callosum on a midsagittal magnetic resonance T2-weighted scan in the group of patients with PC and in the control group without PC. The goal of the study is to determine if there is a relationship between atrophy of the corpus callosum and PC. Such finding would support abovementioned theory of etiopathogenesis of PC.
This study aims to determine size of corpus callosum on midsagittal MR scan in patients with a pineal cyst and to compare it with the control group without a pineal cyst.
