Evaluación imagenológica de los hematomas subdurales

Abstract

Subdural hematoma (SDH), which usually occurs in elderly patients, is a frequently diagnosed condition in neurosurgical departments. Computed tomography (CT) and magnetic resonance imaging (MRI) are the preferred diagnostic modalities for evaluation of SDH. With early diagnosis and proper management, SDH can show a favorable prognosis in most patients. In particular, radiological features related to the internal architecture of the SDH are considered to be closely associated with recurrence in surgically treated SDH patients. OBJECTIVE: In this literature review, we evaluate the various diagnostic modalities of SDH and their imaging characteristics in CT and MRI and classification, through a systematic bibliographical research compiling high-impact evidence-based medicine scientific articles, with the purpose of timely diagnosis and follow-up. METHODS AND MATERIALS: Descriptive, retrospective study where searches were carried out in electronic databases until October 2022 in bibliographic sources such as: PubMed, Scielo, Medscape, published in the last 5 years on the proposed topic. RESULTS: 17 bibliographic reviews were related, where it is described from the main points of view on new concepts, classification and imaging parameters for its diagnosis. CONCLUSION: Knowledge of the imaging findings in patients with SDH allows the evaluation of individual risk from acute to chronic SDH in order to detect in a timely manner to provide treatment and follow-up of said pathology.
