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.
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.
