Giant Sacrum Echinococcosis Secondary to Hepatic Echinococcosis: A Case Report

Abstract

Abstract Background and importance Echinococcosis is a common zoonotic disease found in the liver and lungs. Spinal echinococcosis is typically a secondary infection of other organs and is clinically rare, especially sacral echinococcosis. Methods Case report. Case summary A 52-year-old man presented with lower back pain and numbness in the left lower extremity. MRI showed a large mixed-signal shadow in the sacrum. The patient underwent an intervertebral foramenoscopic cyst decompression and flushing procedure and was subsequently administered albendazole for pain relief. After 5 years of postoperative follow-up, the patient had experienced repeated recurrence with a mean recurrence rate of 22 months and received surgical treatment at each symptomatic visit. Conclusion This report presents the case of a patient with giant sacral echinococcosis that could not be completely removed due to the size of the cyst, providing clinical data for the diagnosis and treatment of sacrum echinococcosis secondary to hepatic echinococcosis.
