Cerebral cavernous malformations: epidemiological, clinical and diagnostic imaging aspects
Journal Title: Progress in Health Sciences - Year 2018, Vol 8, Issue 2
Abstract
<b>Introduction:</b> Cerebral cavernous malformations (CCMs) are one of the most common vascular malformations of the central nervous system. Symptoms of CCMs are not typical; the disease can be asymptomatic or be manifested by a wide range of neurological symptoms.<br/><br/><b>Purpose:</b> To evaluate chosen epidemiologic and clinical issues as well as advanced imaging diagnostics of CCMs in computed tomography and magnetic resonance imaging.<br/><br/><b>Materials and methods:</b> The study was based on retrospective analysis of CT and MRI examinations from the 5 years period. The analysis covered 61 persons, 29 males, and 32 females. The CCMs were diagnosed based on MRI examination in 43 patients and CT in 13 patients.<br/><br/><b>Results:</b> The rate of CCMs occurrence in own material was 0.2%. Single lesions were present in 90.2%, while multiple in 9.8% of cases. Supratentorial CCMs were observed in 77% of cases whereas subtentorial in 23%. Mean size of CCMs in the supra- and subtentorial area equaled 10.6±6.3 and 15.1±5.8 mm, respectively (p<0.05). Clinical symptoms occurred in 65.8% of patients, most frequently in patients with CCMs above 5 mm or with subtentorial lesions. All CCMs were hyperdense in CT images, with calcifications in 13.1%. In MRI, malformations showed diverse intensity of the central part with peripheral low-intensity rim of hemosiderine deposits in T2-weighted images.<br/><br/><b>Conclusions:</b> The clinical symptoms occur in most cases of CCMs. These patients require periodic follow-up MRI examinations, specifically those with haemorrhagic incidents or epileptic seizures, with large size or subtentorial CCMs.<br/><br/>
