Primary spinal extradural hydatid cyst causing spinal cord compression

Abstract

Primary spinal hydatid disease is rare and represents an uncommon but significant manifestation of hydatid disease. We report a case of primary intraspinal extradural hydatid cyst of the thoracic region causing spinal cord compression. The presenting symptoms were mostly atypical and the diagnosis was established preoperatively on the basis of magnetic resonance imaging. The patient underwent surgery resulting in complete recovery and is recurrence-free after 24 months follow-up.

Hydatid disease of the spine: a report on nine patients

“…Anaphlylactic reaction following rupture of the cyst was mentioned by Gopal et al [6]. Of the cases studied one patient developed severe anaphylactic reaction leading to death due to intra arterial dissemination of the small daughter cyst and the fluid.…”

Spinal hydatid with meralgia paresthetica in a female: A rare case report

“…For this reason it is often misdiagnosed initially as tuberculosis of the spine, spinal tumor or disc herniation. [1]…”

“…Overall, a recurrence rate of 30-40% is described and there is a correlation between cyst localization and recurrence. [12] To prevent recurrence it has been recommended that hypertonic saline solution be used during surgery. Mebendazole and Albendazole with their established lethal effect on secondary E. granulosus cyst can be used in the pre-, peri- and post-operative periods.…”

“…Bone involvement is reported in 0.5-4% of the cases, and 50% of those are seen in the spine. [1] Therefore, vertebral hydatidosis is uncommon; however, in endemic areas, physicians should be vigilant in case of relevant patients with mild symptoms, in whom the clinical scenario may well masquerade as other common low-back problems. We present a rare case of primary thoraco-lumbar extradural hydatid cyst presenting as large swelling mimicking lipoma with meralgia paresthetica like syndrome.…”
