Case Report
A 32-year-old woman presented with difficulty walking. She had a 6-month history of back pain and had recently developed bilateral leg weakness. Her physical examination findings were normal. Neurologic examination revealed bilateral lower extremity weakness and hypoesthesia in L4, L5, and S1 dermatomes bilaterally. Routine laboratory investigations and chest radiography findings were normal.
Magnetic resonance imaging revealed a 5X2X2 cm cystic lesion that was located intradurally at the L5-S2
Discussion
Egranulosus is a parasite, distributed mostly in sheep- and cattle-raising countries. Humans can be infected by ingesting the eggs. Oncospheres, which migrate to the portal circulation from the intestine, are trapped by liver and lungs. Spinal hydatid cysts account for 1% of all cases of hydatid disease.10 Spinal hydatid cyst can occur by direct extension from pulmonary or pelvic foci or, less commonly, begin primarily in the vertebral body.6., 8. Also, Echinococcus embryos can the reach the

A Case of Extensive Thoracolumbar Spinal Intradural Cystic Echinococcosis
2022, World NeurosurgeryCitation Excerpt :Patients with cysts confined to the intradural space typically present with compression of the spinal cord. The complete resection of the cysts without rupture is considered curative and feasible in most cases, even in the presence of adhesions to surrounding tissue.2,3 However, in the present case, only oral antiparasitic medication was given as the initial treatment, since the total removal of multiple cystic lesions was considered surgically to be impossible.
Spinal Hydatid Cyst Disease
2017, World NeurosurgeryCitation Excerpt :In liver HC, despite the detection of high positivity rates by serologic methods, monitoring methods are more sensitive than serologic methods for diagnosing spinal HC diseases.43 MRI monitoring is the criterion standard for HC disease.3,5,37,43 Cysts are thin walled, have the same density as cerebrospinal fluid, and do not show septation.
Giant intradural extramedullary spinal hydatid cyst-a rare presentation
2012, Clinical ImagingCitation Excerpt :Spinal hydatid cysts are categorized into five groups: (a) intramedullary, (b) intradural extramedullary, (c) extradural (d) vertebral, and (e) paravertebral. Primary spinal intradural extramedullary type, as seen in our case, is an extremely rare form of hydatidosis [4]. Most common presentation of spinal hydatid includes paraparesis, sensory loss, bowel and bladder dysfunction, radicular pain, and cauda equine syndrome.
Hydatid disease drug therapy primarily to reconstruction of a multilevel thoracolumbar vertebral lesion
2011, Revue de Chirurgie Orthopedique et TraumatologiqueHydatid disease drug therapy primarily to reconstruction of a multilevel thoracolumbar vertebral lesion
2011, Orthopaedics and Traumatology: Surgery and ResearchCitation Excerpt :The preferential locations are the liver (60–70%) and lungs (10–15%). Bone involvement remains rare (0.5–2%), with vertebral locations observed in half of these cases, generally located in a single vertebra [1–4], although multivertebral involvement has been described [5–8]. These cases are marked by neurological complications, relapses, and considerable bone destruction.
