Distant metastasis of liposarcoma to the dura and skull: a case report

A case of metastatic liposarcoma of both skull and brain originating from t he lower extremity is described. A 44-year-old male underwent removal of a myxoid type liposarcoma in his left upper thigh and a second operation for local recurrence. A metastatic liposarcoma was also discovered in the media stinum and treated by radiotherapy. Six years after the initial onset, he p resented with progressive consciousness disturbance, motor aphasia, right h emiparesis and subcutaneous swelling in the left frontal region. Neuroimagi ng showed a large tumour extending both intracranially and extracranially a cross the eroded skull. The intracranial portion of the tumour had invaded the frontal lobe. The tumour was subtotally removed. The operative findings suggested that the tumour had metastasized to the dura mater or the skull initially, and invaded the surrounding tissues. The histological appearance was the same as those of the previous rumours.
