Abstract

A relatively rare condition of ossified chronic subdural hematoma (SDH) mimicking cerebral stroke is presented. A 67-year-old man presented with headache, dysphasia, and left-sided hemiparesis. Routine skull x-ray showed a huge calcification extending from the frontal to the parietal regions in the right side. CT and MRI scan revealed a huge ossified SDH covering the right hemisphere. Right frontoparietal craniotomy was performed and the ossified SDH was completely removed. Severe adhesion was noticed between the pia mater and the inner surface of the ossified mass. The subdural mass had ossified hard outer and inner rims and a soft central part. The postoperative course was uneventful and 3 months after the operation, the patient was neurologically intact. The authors report the successful treatment of a patient with a huge ossified SDH covering the right hemisphere. Careful dissection and total removal are needed in such symptomatic cases to avoid cortical injury and to improve results.
