Hydatid cyst is a parasitic infection caused by Echinococcus granulosis. It mostly involves the liver and lungs; however, muscle involvement is an uncommon event. The diagnosis of such cystic masses is still a challenge due to the presence of more common pathological conditions in soft tissue. Imaging is useful and can identify a definitive diagnosis.
We present a case of a 32-year-old woman with history of close contact with dogs and cats, who complained of an isolated swelling in the right upper thigh growing gradually over a period of 3 years. Ultrasound reported intramuscular hydatid cyst in the right thigh. Hydatid cyst was completely excised. The outcome was good, with no recurrence in one year.
Ultrasonography is an excellent and cost-effective imaging modality with a high negative predictive value in the evaluation of palpable superficial soft-tissue masses and hydatid cysts.
Isolated intramuscular hydatid cyst is rarely reported, even in endemic areas of the disease, so the diagnosis should be considered in any cystic masses of soft tissue, particularly in subjects from high-endemic zones. Although the treatment of choice in such cases is surgical excision but prevention is more favorable to fight against hydatid disease.
包虫囊肿是由细粒棘球绦虫引起的一种寄生虫感染。它主要累及肝脏和肺；然而，累及肌肉的情况并不常见。由于软组织中存在更常见的病理状况，对此类囊性肿块的诊断仍然是一项挑战。影像学检查很有用，能够明确诊断。
我们报告一例32岁女性病例，该患者有与狗和猫密切接触史，主诉右大腿上段孤立性肿胀，持续3年且逐渐增大。超声检查报告右大腿肌内包虫囊肿。包虫囊肿被完整切除。结果良好，一年内无复发。
超声检查是一种出色且经济有效的影像学检查方法，在评估可触及的浅表软组织肿块和包虫囊肿时具有较高的阴性预测价值。
即使在该病的流行地区，孤立性肌内包虫囊肿也鲜有报道，因此对于任何软组织囊性肿块，尤其是来自高流行区的患者，均应考虑该诊断。尽管此类病例的首选治疗方法是手术切除，但预防对于对抗包虫病更为有利。
