title: Primary extradural hydatid cyst extended to paraspinal muscles.
abstract: Primary spinal epidural hydatid cyst without bony involvement is extremely rare. Authors report the case of a 44-year-old female brought to their attention for a rapidly progressive paraplegia. Magnetic resonance imaging (MRI) revealed extradural multiple cysts with "bunch of grapes" appearance extended to the paraspinal muscles through neural foramina without bony involvement on computed tomography (CT) scan. Histopathologic examination after a surgical approach confirmed the diagnosis of hydatid cyst. The early postoperative period showed a progressive improvement of her neurological deficit. The long-term follow-up under discontinued antihelminthic chemotherapy was uneventful.
