Hydatid cyst is a zoonosis caused by ingestion of eggs of Echinococcus‐a tapeworm. Following ingestion of the eggs, oncosphere larvae are released which penetrate the intestinal wall to invade various organs of the body including liver, lungs, and skeletal muscles via. blood vessels. Due to their contractile nature and high lactic acid content, skeletal muscles are typically not a suitable site for attachment of hydatid cyst. In our case report presented below, we report a rare case of an isolated hydatid cyst of paraspinal muscle presenting as a slow‐growing asymptomatic mass in the back, posing a clinical diagnostic dilemma.

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.

Background. Cystic echinococcosis is considered a public health problem that if left untreated can have dangerous consequences for the person. The disease is caused by Echinococcus granulosus sensu lato larvae. The main risk factors for this parasitic infection are habitat, direct contact with dogs, use of raw vegetables, and use of unwashed vegetables. The most important factors affecting the prevalence of HCD are economic, occupational, agricultural, educational, and factors related to public health and cultural habits of the general public in that geographical area. Objectives. The purpose of this study was to investigate the prevalence of the types of cystic echinococcosis genotypes (E. granulosus sensu stricto (G1-G3) and E. Canadensis (G6 and G7)) in livestock in Iran. Method. This systematic review was conducted, using Medline/PubMed, Scopus, Web of Sciences, and Google Scholar databases, to identify studies of cystic echinococcosis in animals published from 2010 to April 14, 2021. Finally, 28 studies were selected for meta-analysis, which was analyzed using Stata software version 14. The cystic echinococcosis prevalence with 95% confidence intervals of animals was synthesized using the random effect model. Heterogeneity was evaluated and in cases where the I 2 index was higher than 75%, subgroup analysis was performed according to the types of animals. Result. The highest prevalence of cystic echinococcosis infection was related to G1 genotype ( P = 0.91 (95% CI = 0.84 , 0.97 )) and the prevalence was related to G2 genotype ( P = 0.07 (95% CI = 0.00 , 0.18 )). The results of the subgroup analysis showed that in the G1 genotype the highest prevalence was observed in Goats and Buffaloes with P = 1 (95% CI = 0.96 , 1 ) and P = 1 (95% CI = 0.97 , 1 ), in the G3 and G6 genotypes the highest prevalence was observed in camels with P = 0.50 (95% CI = 0.31 , 0.69 ), and P = 0.45 (95% CI = 0.22 , 0.69 ), respectively. Conclusion. The cystic echinococcosis genotypes vary from region to region or from country to country and also from host to host, and according to the results, it should always be stopped in areas where the prevalence of such genomes suitable for livestock as well as human food sources to prevent infection of livestock and thus human exposure to cystic echinococcosis.
