A subdural-peritoneal shunt was placed in a geriatric patient who had a chronk subdural hematoma (CSH). After the procedure, a second CSH developed on the contralateral side, and this hematoma resorbed spontaneously without further intervention. This patient's treatment is discussed relative to the various subduralperitoneal shunt options currently used to address CSH. The case is also evaluated in light of our experience with other CSH cases and other reports in the literature.
