PRESENTATION OF BRAIN ABSCESS IN DIFFUSION-WEIGHTED MR IMAGING

Description

Brain abscess is a serious infection of the cerebral parenchyma, which endangers the lives of patients. According to the relevant literature there is a high mortality rate of approximately 10% and can reach up to 80%. Due to the high morbidity and mortality, the need for early diagnosis and prompt treatment is of a particular importance. RM plays an important role in differentiating different brain lesions due to its high resolution and examination possibilities in different plans. The DWI (Qualified Diffusion Imaging) sequence is a much more sensitive and efficient tool than conventional RM in diagnosing brain abscess due to its ability to detect water diffusion restriction. Early diagnosis through RM with DWI would eliminate the need for invasive diagnostic and surgical procedures and enable early initiation of treatment and thus significantly reduce the morbidity of this condition.

The objective of this study is to determine the diagnostic accuracy with the DWI sequence in the diagnosis of brain abscesses as well as common and uncommon presentations, based on histopathological findings.

Material and methods:

This retrospective and prospective study was conducted in the cabinet of the Republic of Macedonia at the Radiology Clinic of UCC of Kosova during a period of six months from March 2017 to August 2017. 18 patients were selected to conduct this study.

Results:

Out of 18 patients, 8 patients were diagnosed as brain abscess by histopathological examination. Of these 8 patients, 7 patients were positive in the DWI sequence. Therefore, RM examination and DWI sequence had 90% sensitivity, specificity, and accuracy in diagnosing brain abscess. It was proved that pyogenic abscesses have typical presentation in DWI.
