METHODS: We report a case of a giant muscle hydatid in the lower extremity, with neurological symptoms as the first manifestation. The symptoms specifically manifested as intermittent pain in the right lower extremity and numbness in the sole of the right foot. However, there were no obvious abnormalities detected in electromyography and lumbar MRI. Subsequent ultrasonography and calf MRI showed that the patient had cystic lesions in the calf. The patient was initially diagnosed with a muscle hydatid cyst. Treatment involved complete surgical excision of the lesion, and the diagnosis of a hydatid cyst was confirmed through macroscopic and microscopic histopathological examination after the mass was excised. The patient was given oral albendazole, and no recurrence was observed during the 12 months of follow-up.
CONCLUSIONS: This case underscores the need to consider hydatid disease when diagnosing soft tissue masses in muscles, particularly in endemic areas. Patients may initially present with atypical symptoms like peripheral nerve issues.
方法:我们报告一例下肢巨大的肌肉包虫,以神经症状为第一表现。症状具体表现为右下肢间歇性疼痛和右脚脚底麻木。然而,肌电图和腰椎MRI均未发现明显异常。随后的超声检查和小腿MRI显示患者小腿有囊性病变。患者最初被诊断为肌肉包虫囊肿。治疗包括完全手术切除病灶,切除肿块后,通过宏观和微观组织病理学检查证实了包虫囊肿的诊断。患者口服阿苯达唑,在12个月的随访中没有观察到复发。
结论:该病例强调在诊断肌肉软组织肿块时需要考虑包虫病,特别是在流行地区。患者最初可能会出现非典型症状,如周围神经问题。
