Computerised tomography of intracranial subdural haematoma in Ibadan

Abstract

The high mortality and morbidity associated with intra-cranial subdural hematoma (SDH), has declined significantly with the introduction of Computerized Tomography (CT) for the evaluation of the brain in suspected cases. One hundred patients with CT-diagnosed SDH at the Radiology department of the University College Hospital, Ibadan between January 1999 and December 2000 were reviewed. The mean age was 47.4 years. T h e most frequent cause of SDH was head injury 61 (61%). The observed CT appearance s of S DH included 66(66%) of chronic (hypodense), 30(30%) of acute (hyperdense) and 4(4%) of acute en-chronic (mixed density) lesions. There were mor e unilateral 83(83%) lesions than bilateral 17(17%). The lesions were right-sided in 45(45%) case s and left-sided in 38(38%). A total of 169 lesions were detected as some patients had multiple sites, however, the parietal 78(46.2%) and frontal 64(37.9%) lobes were mostly affected. We conclude that brain C T scan offers the advantage of prompt determination and precise anatomical localization of SDH, which significantly aids management.
