ABSTRACT
Introduction: Chronic subdural hematoma is a hematoma encapsulated by two internal and external membranes. There are different imaging classifications that include the characteristics of these lesions, but the presence of the membranes and their characteristics is a little described aspect. Objective: To describe the tomographic characteristics of the membranes of chronic subdural hematomas. Methods: A descriptive study was carried out in the Neurosurgery service in conjunction with the Imaging service of the Manuel Ascunce Domenech University Hospital during the year 2021. 20 adult patients who underwent surgery with the diagnosis of chronic subdural hematoma were included. The membranes were characterized according to their density, thickness, number of layers, morphology and extension. Results: Male patients over 65 years of age predominated, with more frequent unilateral hematomas on the left side. The average volume was 150 ml and the diameter was 3 cm. Thin, hyperdense, incomplete, single-layer membranes were more frequent, and the morphology was variable. Conclusions: The membranes that make up the chronic subdural hematoma can be seen on computerized axial tomography. Different types of membranes have been found according to their density, thickness, morphology, extension and presence of septa. The presence of a thick or thin membrane with septa may indicate a craniotomy that allows careful resection of the parietal membrane and sufficient opening of the visceral membrane to facilitate brain re-expansion and reduce the incidence of recollections.REFERENCES
