Epidural metastasis of a glioblastoma after stereotactic biopsy: Case report

Tumor seeding along the biopsy tract is a rare complication in stereotactic biopsy. We present the unique case of a 42-year-old male with epidural tum or seeding along the needle tract after computer tomography-guided stereota ctic biopsy of a glioblastoma in the right basal ganglia. Three months afte r the biopsy and one week following fractionated radiation therapy, the pat ient died of brain edema and cardiac dilatation. Besides further tumor grow th at the primary site, autopsy revealed a right frontal epidural, nodular metastatic tumor at the site of dura incision of the stereotactic biopsy. H istological examination showed a glioblastoma that spread epidurally along the needle tract. This is the first report of an epidural intracranial impl antation metastasis of a glioblastoma after stereotactic biopsy.
