Subdural empyema and brain abscesses in patient with a purulent sinusitis Subdural empyema and brain abscesses in patient with a purulent sinusitis

Purpose. To describe computed tomography (CT) and magnetic resonance imaging (MRI) features of subdural empyema and brain abscesses of the frontal lobe during initial diagnosis and in the postoperative period.

Materials and methods. Literature review and a case study of subdural empyema and brain abscesses of the frontal lobe are presented. Tomograms before and after surgery were obtained with the use of CT scans HiSpeed DX/i (General Electric) and Ingenuity (Philips); and MRI scan Panorama with magnetic field 1Т (Philips).

Results. The diagnosis of subdural empyema and brain abscess of the frontal lobe was verified after surgery. Possibilities of CT and MRI in diagnosis of subdural empyema and brain abscesses of the frontal lobe, as well as in the evaluation of surgical treatment results were described.

Conclusion. Early and accurate diagnosis of subdural empyema and brain abscesses of the frontal lobe is essential for successful surgery. The method of choice for the diagnosis of these pathologies is computed tomography, since it allows to accurately define level and size of an intracranial inflammatory lesion, the state of all brain structures, as well as bones of a skull and facial skeleton. It also allows evaluating changes in paranasal sinuses in the preoperative period and after surgery. It is advised to use MRI to evaluate results of a surgical treatment with more detail.
