Osteolytic bone lesion: vertebral alveolar echinococcosis in a patient with splenectomy

Osteolytic lesions are not always related to malignancies. We report an 82-year-old woman suffering from subcostal pain. The patient underwent a splenectomy 40 years previously. CT-scan and MRI highlighted a calcified hepatic lesion associated with an osteolytic lesion of the L5 vertebra. Osteolytic and hepatic lesions were attributed to an alveolar echinococcosis based on positive serological assays. To our knowledge, this is the first report of an alveolar echinococcosis in a patient with splenectomy and secondary lesions. We suggest that the splenectomy could have promoted the parasite spreading to vertebra.
