Case:
A 54-year-old man presented with low back pain and low-grade fever. Palpation revealed a focal mass of the lumbar region. Radiographs were normal, but magnetic resonance imaging demonstrated a multicystic mass at the level of L2-L4. The initial diagnosis of a hydatid cyst was confirmed after surgical excision.
Conclusion:
Although primary paraspinal hydatidosis is rare, physicians should be aware of it when dealing with patients suffering from low back pain combined with red-flag symptoms. Especially in rural regions or areas where populations live in close proximity to host animals, primary paraspinal hydatidosis should be included in the differential diagnosis.
