A multilocular extradural cervical spinal hydatid cyst that causes severe spinal cord compression and quadriplegia is relatively rare and difficult to treat. In a patient with this disorder, computerized tomography-guided needle aspiration of the cyst loculations and irrigation using hypertonic saline eliminated the need for emergency surgery and provided complete resolution of the patient's quadriplegia. The subsequent course of the disease was controlled by treatment with albendazole. Magnetic resonance imaging performed 4 months after the procedure demonstrated collapsed cysts and absence of spinal cord compression.
The surgical treatment of spinal tumors depends on a host of factors that include: the type of tumor and its location within the spine, the presence or absence of neural compression, the portion of the vertebrae involved, the anticipated mode of spinal failure, the biology of the tumor, the anticipated life expectancy of the patient, and the type of prior or subsequent adjuvant treatment. Two thirds of all spinal tumors arise from the vertebral body and only 1/3 originate from the posterior elements. Malignant tumors more commonly involve the vertebral body and benign lesions usually are located posteriorly. Malignant tumors, because of their aggressive nature and their propensity for anterior vertebral body involvement, are associated with a higher incidence of neurologic deficit than are benign lesions. The surgical treatment of spinal tumors is dictated largely by the location of the tumor within the spine; anterior vertebral body tumors generally should be approached anteriorly, whereas posterior lesions should be approached posteriorly. Because most malignant tumors, whether primary or secondary (metastatic), are located anteriorly within the vertebral body, most surgery for malignant tumors should be approached anteriorly. Anterior decompression should be accompanied by reconstruction with biologic materials such as autogenous bone graft unless life expectancy is certain to be very limited (<6 months).
