Case report: a rare case of intradural and pleural wall cystic echinococcosis

Background Cystic echinococcosis (CE) is prevalent in livestock farming regions around the world. However, it remains relatively rare compared to other infectious diseases. CE typically affects the liver, lungs, brain, and kidneys. Spinal and pleural wall involvement is exceedingly rare. We report a unique case of intradural and pleural wall CE in a young male, successfully treated with surgery and postoperative medication. Case presentation A 19-year-old Tibetan male from the Qinghai-Tibet Plateau was diagnosed with intradural and pleural wall CE through imaging, serology, and surgical pathology. According to the Dew/Braithwaite & Lees (BL) classification, his condition was an exceptionally rare form of spinal echinococcosis, compounded by an even rarer pleural wall involvement. Prompt surgical intervention and postoperative medication resulted in significant improvement in spinal cord compression symptoms. Conclusions This case highlights the diagnostic and therapeutic challenges of rare CE locations. MRI proved superior to CT in diagnosing bony cystic echinococcosis. Early surgical intervention combined with medication facilitates spinal cord function recovery, providing valuable insights for managing similar cases.
