Chronic epidural hematoma with frontal skull-base destruction mimicking osteogenic tumor, associated with coagulopathy due to chronic hepatitis C

BACKGROUND: Intracranial epidural hematoma is generally evoked by acute coup-injury. Though rare, it has a chronic clinical course and can be a non-traumatic event. CASE DESCRIPTION: The patient was A thirty-five-year-old man with a complaint of one-year history of hand tremor. He was suspected diagnosis of osteogenic tumor with differential diagnosis of epidural tumor, or abscess in the right frontal skull base bone, associated with chronic type C hepatitis because of his plain CT and MRI. RESULTS: Results of examinations and surgery, the extradural mass was chronic epidural hematoma without skull fracture. We diagnosis he is the rare case of chronic epidural hematoma caused by coagulopathy due to chronic hepatitis C. CONCLUSION: We reported a rare case of chronic epidural hematoma caused by coagulopathy due to chronic hepatitis C. The repeated spontaneous hemorrhage in the epidural space formed the capsule and destruction of skull base bone, just mimicking skull base tumor.
