“…In this regard, a meta-analysis by Khalkhali et al on the prevalence of hydatid cysts in Iran found that although the rate of infection with hydatid cysts was higher in females than males, the difference was not statistically significant [6]. Thus, in some areas, a greater frequency of CE in males may be seen [25][26][27].…”

Background: Cystic echinococcosis (CE) is considered as a neglected disease with significant mortality and morbidity in most of the developing countries. The current study aimed to retrospectively assess the demographic and epidemiologic features of human CE surgical cases in a 15-year period in Fars province, southwestern Iran. Methods: A 15-year (2004-2018) retrospective study was conducted to find out the epidemiological and clinical picture of CE in patients who undergone surgeries for CE in two main hospitals in Fars Province, southwestern Iran. Hospital records were reviewed, and data were retrieved from each CE patient's record. Results: A total of 501 CE surgical cases were recorded during a 15-year period, corresponding to an average annual incidence of 33.4 and a surgical incidence rate of 0.74/100,000 population. Of these, 242 (48.6%) were male, and 256 (52.4%) were female. Patients' age ranged from 2 to 96 years, with a mean age of 34.92 (± 19.87) years. A significantly higher rate of CE cases was noted in subject's ≥ 50 years of age. The highest frequency of cases (62: 12.5%) was recorded in the year 2017. The most commonly involved organs were liver (339 cases; 57.8%) and lung (279 cases; 47.6%). Concurrent involvement of two organs was seen in 58 (9.9%) cases of both lung and liver, 10 (1.6%) cases of lung and other locations (but not liver), and 23 (3.9%) cases of liver and other locations (but not lung). Reoperation was noted in 67 (13.4%) of the cases. The size of the lung hydatid cyst varied, ranging between 2 and 24 cm (mean = 7.33, SD = 3.737). The size of liver hydatid cysts ranged from 1 to 26 cm (mean 9.04, SD = 4.275). Conclusion: The findings of the current study demonstrated a nearly constant prevalence of CE during the last 15 years in southern Iran. Further studies are needed to find out the reasons behind the recurrence of the disease, which is substantial, in surgically-treated patients.

“…The contractile nature of the muscles and the high lactic acid content make muscles not a suitable site for implantation of hydatid cysts 3 . Among various muscle groups too, paraspinal muscles are much more rarely affected 7,8 …”

“…Hydatid cyst of muscle usually presents as a painless, slow‐growing, asymptomatic mass with a normal overlying skin, similar to our case presented above. A high index of suspicion is therefore necessary as its differential diagnosis can range from chronic hematoma and lipoma to malignant soft tissue tumors such as myxoid liposarcoma 7–9 . The diagnosis of hydatid cysts is initially sought with serology and imaging findings 10–12 .…”

Intramuscular hydatid cyst of paraspinal muscle: A diagnostic challenge

Clinical Case Reports

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.

“…However, in studies conducted by Cohen et al (1998) and Qaqish et al (2003) such associations were not observed [17,18]. Thus, in some areas, based on the culture and social criteria, men may cover the highest rate of CE infection [19][20][21].…”

Patients' age ranged from 2 to 96 years, with a mean age of 34.92 (±19.87) years. A significantly higher rate of CE cases was noted in subjects ≥ 50 years of age.

The size of liver hydatid cysts ranged from 1 to 26 cm (mean: 9.04, SD= 4.275). Conclusion: The findings of the current study demonstrated a nearly constant prevalence of CE during the last 15 years in southern Iran.
