A primary spinal hydatid cyst.

ABSTRACT

Hydatid disease occurs in humans as a result of faeco-oral contamination. Spinal hydatid cyst is a rare entity and a serious form of hydatid disease affecting less than 1% of the total cases of hydatid disease. Neural compression is common in vertebral hydatidosis where prognosis is always considered as very poor. Difficulty in management due to recurrence of this rare entity makes it a challenging disease to eradicate entirely. Efficacy of use of anthelminthic even after complete surgical removal is yet to be established. We are reporting diagnosis and management of a case of primary extradural and paraspinal hydatid cyst (HC) in an otherwise healthy patient who did not show any other evidence of systemic hydatid disease. The diagnosis was recognized preoperatively by magnetic resonance imaging (MRI) and confirmed postoperatively by histopathology. Surgical removal of the cysts/lesions was followed by anti-helminthic medication and recovery was satisfactory until the patient had recurrence after one year. The patient underwent surgery for the second time and was given anti-helminthic again for a longer period and was recurrence free for the next one year.
