“…Sometimes, the recurrence of infection or worsening symptoms may result in incomplete debridement surgery. Then preoperative and postoperative anti-parasite chemotherapy was considered an effective treatment regimen to control the spread and recurrence of cyst lesions [3,14,17]. In our study, all patients were successfully treated by surgery combined with anti-parasite chemotherapy.…”

“…Unlike visceral echinococcosis disease, infestation development of bone echinococcosis began in blood-rich cancellous bone. Because there was no reactive connective tissue barrier against the proliferation of intraosseous hydatid cysts, daughter cysts can directly enter the bone and grow in the bone marrow cavity along the direction of the epiphyseal plate and articular cartilage [14]. In the view of imaging, the lesion showed that expansive honeycomb or soap bubble changes with smooth and sclerotic margins.…”

Purpose: The study aimed to access the clinical efficacy of surgery combined with anti-parasite chemotherapy in the treatment of advanced pelvic echinococcosis.Methods: From March 2005 to December 2018, the medical records and imaging of patients with pelvic echinococcosis were retrospectively evaluated, who were treated with surgery combined with anti-parasitic chemotherapy. The Enneking classification was applied to determine the location of the lesion, and the Musculoskeletal Tumor Society (MSTS) score system was used for outcome evaluation.Results: A total of 9 patients who met the criteria were included in this study, with a mean follow-up time of 4.36 ± 3.11 years. All patients were successfully treated by surgery combined with anti-parasite chemotherapy. Three patients with recurrence of pelvic echinococcosis, and the infection was under control after repeated debridement procedures. Superficial wound skin necrosis of surgical incision occurred in one case and recovered after repeated debridement.Conclusion: Surgery combined with anti-parasite chemotherapy was a practical method in the management of advanced pelvic echinococcosis. Standard anti-parasite chemotherapy played an essential role in the whole treatment.

“…While, the current treatment for bone location is medico-surgical [5]. The medical treatment is based on Albendazole [16,17], its aims are to reduce the cysts size, sterilize their contents preoperatively and postoperatively to treat small cysts that have gone unnoticed [5]. Surgical treatment consists of a "carcinological" excision of the lesions which can be compared to a true malignant tumor.…”

Background: Hydatidosis is a parasitic disease linked to the development of Echinococcus Granulosus larval form in humans. This anthropozoonosis is characterized by many topographical and evolutionary aspects. Musculoskeletal hydatidosis is rare, it represents only 0.9 to 2.5% of all locations. Objective: the aim of this manuscript is to report a rare case of bone and muscle location of hydatid cyst and show the imaging contribution in its positive diagnosis and pre-therapeutic assessment. Method: We report the observation of a 61-year-old man admitted to our training for a right thigh mass, revealing a muscular hydatid cyst with a concomitant iliac bone location. Result: Ultrasound examination shows an intra muscular cystic lesion, of the Sartorius and rectus femoris muscles, with hydatid membranes inside. A simultaneous bone location, at the ipsilateral iliac bone, was fortuitously discovered on CT scan and MRI exploration, which show a multicystic lytic lesion with cystic signal and round daughter cysts on MRI examination. A complementary X-ray of the pelvis shows the classic "honeycomb" appearance of the right iliac bone. A positive hydatid serology confirmed the diagnosis. No concomitant hepatic or pulmonary localization was demonstrated on abdominal ultrasound and chest CT scan. An anthelminthic therapy (Albendazole) was started, and the patient was a candidate for further surgical treatment. Conclusion: Musculoskeletal hydatid cyst location is rare. The Hydatid osteopathy is usually infiltrative, slow and progressive, which makes diagnosis late and compromises the quality of treatment. So, despite its rarity; musculoskeletal hydatid cyst should always be considered in the differential diagnosis of cystic lesions in endemic areas.
