Hydatid cyst of the thigh mimicking a tumour mass: a rare case and diagnostic challenge – A case report
Introduction: Hydatid cysts (HD), caused by the parasitic infection Echinococcus granulosus, may affect several organs, most commonly the liver and lungs. Involvement of the musculoskeletal system is extremely rare, thus posing unique diagnostic challenges. Presentation of the case: We report the ca...

| description | Introduction: Hydatid cysts (HD), caused by the parasitic infection Echinococcus granulosus, may affect several organs, most commonly the liver and lungs. Involvement of the musculoskeletal system is extremely rare, thus posing unique diagnostic challenges. Presentation of the case: We report the case of a 61-year-old homeless man who presented with a progressively enlarging mass and swelling of the right thigh, that he had first noticed 6 months prior to the appointment. General physical examination and radiological evaluation revealed a multilocular intramuscular cystic mass in the thigh, extending into the pelvis region with pelvic bone involvement, as well as a multilocular cystic lesions in the liver, lungs, and one kidney. Serological testing via Enzyme-Linked Immunosorbent Assay (ELISA) confirmed the diagnosis of hydatid disease. Due to the extensive size of the cystic masses, surgical intervention was deemed unfeasible. The patient was treated with albendazole (400 mg twice daily), with improvement in both local and general condition. The patient currently resides in a nursing home and requires regular follow-up appointments at the hospital due to a decline in his general health. Over the past two years, he has been diagnosed with atrial fibrillation, hypertension, atherosclerosis, heart failure, and post-stroke epilepsy. Discussion: Surgical removal is regarded as the optimal treatment of hydatid disease; however, in cases involving large cysts, radical resection might not be viable. In such scenarios, causal treatment with antiparasitic medication can be an effective alternative. Conclusion: Hydatid cysts in the musculoskeletal system are rare but can mimic tumour-like masses, making diagnosis difficult. Surgery remains the gold standard for treatment of the disease. |
