Abstract

The patient was a 46-year-old male, who suffered from mild head trauma in January 2002, and general convulsions with unconsciousness on February 28. Slight right hemiparesis and aphasia were presented after the epilepsy attack. CT scan revealed a large lesion of mixed density occupying the left temporal space. It showed linear high density in its medial margin and had compressed the left temporal lobe strongly, causing mid-line shift. The lesion was suspected to be a calcified chronic subdural hematoma and the patient was admitted to our hospital on February 28. The symptoms had improved the next day but they began to get worse again gradually after admission. T1-weighted MR image showed high intensity areas under the subdural hematoma, which were suspected to be subcortical hemorrhage. Six days after admission, consciousness disturbance became progressive. The calcified hematoma had not enlarged but brain edema had increased. On CT, an operation was performed and the calcified old hematoma and the new subdural hematoma surrounding it were removed. The diagnosis of organized chronic subdural hemaotma was made at the time of the operation. The contents of this calcified subdural hematoma was mostly old dark-gray substance, but some fresh bleeding point was seen at the inner surface of the outer membrane. At the bottom there was a hard, calcifield layer which adhered tightly to the brain. Adhesion between the inner membrane of the hematoma and brain surface which related to the subcortical hemorrhage was presented. It seemed impossible to remove the inner membrane without damaging the brain so no attempt was made to do so. The aphasia and right hemiparesis improved 3 weeks after the operation and the patient was discharged on April 4. He has no neurological deficits and is under periodic observation. A calcified chronic subdural hematoma has rarely been encountered and the etiology, imaging diagnosis, and management are unclear. We presented the interesting image findings on this case and discussed the etiology of this disease.
