Abstract
Spinal hydatidosis is a rare and often overlooked manifestation of echinococcosis caused by Echinococcus granulosus. We present the case of a 35-year-old female patient from a rural area who presented with progressive lower back pain and heaviness in the lower limbs. Magnetic resonance imaging (MRI) revealed multiloculated cystic lesions at the L3 and L4 vertebrae, suggestive of hydatid disease. The patient underwent surgical excision of the cysts and spinal stabilization, along with albendazole therapy administered pre- and postoperatively. The parasitological examination of the surgical specimen confirmed the diagnosis. The postoperative course was uneventful, and no signs of recurrence were observed at the three-month follow-up. This case underscores the importance of including spinal echinococcosis in the differential diagnosis of vertebral lesions, particularly in endemic regions and among patients with risk factors such as close contact with dogs. Early diagnosis through imaging and a combined surgical-medical treatment approach are crucial for favorable outcomes.
