Hydatid disease is a zoonotic infection caused by the tapeworm, primarily affecting the liver and lungs, and rarely involving muscle tissue. Humans are infected by ingesting eggs from contaminated food or water. Patients may present with painless, slow-growing masses, sometimes associated with nerve or vessel compression, especially in cases of muscle involvement. Diagnostic imaging techniques such as ultrasonography, CT scan, and MRI are essential for preoperative evaluation. Treatment involves surgical removal of the cyst with careful lavage to prevent recurrence, followed by anti-parasitic medication. Our case involves a young female with a previously treated pulmonary hydatid cyst, who presented later with numbness and pain in her left lower limb, revealing a psoas location of hydatid disease exerting direct compression of the cauda equina. This case underscores the importance of including hydatid disease as a potential differential diagnosis for soft tissue masses in endemic areas, even with an atypical clinical presentation.
包虫病是一种由绦虫引起的人畜共患感染病，主要影响肝脏和肺部，很少累及肌肉组织。人类通过摄入受污染食物或水中的虫卵而感染。患者可能出现无痛、生长缓慢的肿块，有时伴有神经或血管受压，尤其是在肌肉受累的情况下。超声、CT扫描和MRI等诊断成像技术对术前评估至关重要。治疗包括手术切除囊肿并仔细冲洗以防止复发，随后使用抗寄生虫药物。我们的病例是一名年轻女性，曾接受过肺包虫囊肿治疗，后来出现左下肢麻木和疼痛，发现包虫病位于腰大肌，对马尾神经造成直接压迫。该病例强调了在流行地区，即使临床表现不典型，也应将包虫病作为软组织肿块的潜在鉴别诊断之一的重要性。
