Clinical Evaluation of the Traumatic Subdural Hygroma

ABSTRACT

Traumatic subdural hygroma has received little attention in the literature, the authors experienced 17 cases of traumatic subdural hygroma after introduction of Computerized Tomography(CT) since October 1977 in Kyung Hee University Hospital. Characteristics in CT of our experienced traumatic subdural hygromas were almostly bilateral and located on the anterior aspect of the interhemispheric fissure, frontal and frontotemporal side with decrease density as like cerebrospinal fluid. Subdural hygroma easily differentiated with subdural hematoma by use of the CT scan. Subdural hygroma usually respond readily to evacuation of watery yellowish or cerebrospinal fluid-like fluid through simple burr hole, conservative treatment effected only 3 cases out of 17 subdural hygromas.
