Primary solitary Echinococcosis in cervical spine. Postsurgical successful outcome after long-term albendazole treatment.
METHODS
A case report of a young man with isolated cervical hydatidosis treated postoperatively with sustained cyclical albendazole therapy for 9 years of follow-up.


OBJECTIVE
To communicate the efficacy and safety of prolonged albendazole treatment in the postoperative management of spinal hydatid disease, and recommend therapeutic regimes for preventing its recurrence.


BACKGROUND
Bone involvement in hydatid disease is uncommon and the cervical region of the spine is rarely affected. Surgical excision remains the treatment of choice but high rates of postoperative recurrence have highlighted the importance of adjuvant anthelmintic therapy. The selection of the drug(s) and the duration of the medical treatment is still controversial.


METHODS
The patient described herein presented with isolated bone lesions, in an unusual cervical location, and without coincidental visceral involvement. Therefore, diagnosis was delayed and surgical debridement was carried out without any preoperative anthelmintic therapy. To prevent late recurrences, therapy with intermittent courses of albendazole has been maintained for nine years and is still ongoing. Response and toxicity related to therapy has been closely monitored by clinical, biochemical and radiological follow up.


RESULTS
After surgery the patient has remained asymptomatic without sequelae or evidence of relapses. No clinically relevant side effects has been observed.


CONCLUSIONS
Prolonged albendazole treatment appears to be safe and effective in the prevention of late recurrences after spine hydatidosis surgery. Long-term chemotherapeutic schedules should be considered after surgical excision of spine or bone lesions.
