Introduction: Hydatid cysts are rarely detected in muscle tissue (0.7-0.9%), even in endemic countries. The aim of this study was to present information regarding the clinical manifestations, diagnosis, and management of muscle echinococcosis. Methods: Twenty-two patients with hydatid cysts in the muscle were followed from January 2006 through December 2014. Results: Twenty-four sites of muscle involvement were observed in the 22 patients. Fifteen (68%) of our patients were women, while seven (32%) were men. The mean age was 28.1 ± 15.4 (6-61) years. The most frequent locations were the thigh (27.2%) and the paravertebral region (13.6%). Most patients reported a painless slow-growing mass with normal overlying skin. Most (90.2%) cases were treated by surgical excision and fi ne-needle aspiration. Conclusions: Primary muscle hydatid cyst should be considered in the differential diagnosis in cystic masses of the muscular system without pain and localized enlargement of soft tissue, especially in endemic areas. Hydatid cyst should be investigated using serological tests and imaging modalities. If possible, total surgical excision of hydatid cyst in the muscle should be performed.

“…In fact, <30% of serologies were positive in a cohort of patients with musculoskeletal echinococcosis of echinococcosis of liver while for musculoskeletal hydatosis they were positive in only 26% -28% of case [7]. Pericystectomy constitutes the best surgical approach for the treatment of muscular HC in cases of small superficial cysts or cysts not adhering to vascular nerve [8] [9].…”

Introduction: Hydatid disease is a parasitic disease caused by Echinococcus species, and is a serious sometimes fatal, that is endemic in many parts of the world, especially in South America, the Middle East including Yemen, Australia, and the mediteranean region. Hydatid disease of the skeletal muscle is rare. Presentation of Case: This article presents an unusual three Yemeni cases of subcutaneous and intramuscular hydatid cyst of the thigh. The ages of one male and two women are 32, 38 and 27 years respectively. They admit to IBN Sina hospital complain of dull aching pain, but no fever or other symptoms indicating infection or metastatic neoplastic soft tissue mass, lipoma or cystic swelling for differential diagnosis. Clinical manifestation was nonspecific and the diagnosis mainly depends on radiological evaluation which included mainly CT, MRI and laboratory investigation which is mainly ELISA test for Echinococcus granulosus Ab. After the patient admitted to the hospital, preoperative albenazole for ten days to treat patient, and surgical excision procedure pericystectomy were performed for the cyst combined with postoperative albendazole. In our 3 cases, this surgical approach was performed to extract the hydatic cyst completely intact without rupture and was achieved in 2 cases, while rupture occur in one case (case No. 3). The cyst was ruptured during intramuscular dissection. In spite of that, she passed well without intra or post-operative early or late complications. Use of intra-operative hypertonic 10% saline solution is mandatory to prevent the dissemination of protoscoleces. Chemotherapy enabled the authors to treat the patient with preoperative albenazole for ten days and to prevent postoperative recurrence of the disease. Discussion: The diagnosis of echinococcosis should be considered when soft tissue mass grows slowly for months or years, in any patient from the endemic area. Patients presented with this rare hydatic cyst diseses in subcutaneous and intramuscular space of the thigh,

“…The Echinococcus natural habitat is the small intestine of carnivores (1,(6)(7)(8). Two species of Echinococcus (E. Granulosus and E. Multilocularis) cause cystic echinococcosis and alveolar echinococcosis in humans.…”

Hydatid cyst in the vastus lateralis muscle: a case report

SummaryHydatidosis is a zoonotic disease; human infection occurs through the consumption of food and water contaminated with the eggs of parasites of the Echinococcus type. While the liver is the most common site of infection, involvement of the musculoskeletal system is extremely rare. In the context of musculoskeletal involvement, the spine is the most commonly infected site, while the muscles are rarely infected and account for approximately <1% of cases. It has been suggested that muscles provide an unsuitable environment for the parasite, because of the presence of lactic acid. The cysts appear as slow-growing masses of soft tissue, and signs of inflammation and fistulization often coexist. We report a rare case of an hydatid cyst located in the vastus lateralis muscle of a 41-year-old man. Muscular echinococcosis is an extremely rare disease. A MRI evaluation should be taken into account as gold standard in the diagnosis. Surgical cystectomy is often indicated, and an excision with wide margins is mandatory to avoid the rupture of the cyst and anaphylaxis. Adjuvant pharmacological therapy is recommended to minimize the risk of recurrence.
