Extension of echinococcal spinal infestation extra- and intradurally after a decade of extinction

Simultaneous intradural, extradural, vertebral and paravetebral invasion of hydatid cyst, pathologic fracture, and multiple vertebral involvement are all rare encountered conditions in echinococcal infestation. A 48-year-old man who had experienced a falling down trauma, 10 years ago, and at that time, because of L1 burst fracture, undergone on Harrington rod placement, admitted in our ward for newly started urinary retention and mild paresis of lower extremities. With imaging analysis and during surgery, we discovered the extension of echinococcal spinal infestation extra- and intradurally after a decade of extinction. We performed a double stage circumferential reconstruction and adjuvant long term chemotherapy. We closely monitor our patient neurologically and radiologically and believe that aggressive surgical treatment and sustained cyclical albendazole therapy can increase the quality of life and life expectancy.
