“…Patients may present with symptoms of a slowly growing mass or acute pain due to cyst rupture. Alternatively, muscular involvement may be incidentally detected on radiographic studies showing a calcified Echinococcus cyst (34,202). The thigh is a common location for cysts, but paraspinal, pelvic, deltoid, and psoas locations have also been described (73,202,230).…”

SUMMARY Infectious myositis may be caused by a broad range of bacterial, fungal, parasitic, and viral agents. Infectious myositis is overall uncommon given the relative resistance of the musculature to infection. For example, inciting events, including trauma, surgery, or the presence of foreign bodies or devitalized tissue, are often present in cases of bacterial myositis. Bacterial causes are categorized by clinical presentation, anatomic location, and causative organisms into the categories of pyomyositis, psoas abscess, Staphylococcus aureus myositis, group A streptococcal necrotizing myositis, group B streptococcal myositis, clostridial gas gangrene, and nonclostridial myositis. Fungal myositis is rare and usually occurs among immunocompromised hosts. Parasitic myositis is most commonly a result of trichinosis or cystericercosis, but other protozoa or helminths may be involved. A parasitic cause of myositis is suggested by the travel history and presence of eosinophilia. Viruses may cause diffuse muscle involvement with clinical manifestations, such as benign acute myositis (most commonly due to influenza virus), pleurodynia (coxsackievirus B), acute rhabdomyolysis, or an immune-mediated polymyositis. The diagnosis of myositis is suggested by the clinical picture and radiologic imaging, and the etiologic agent is confirmed by microbiologic or serologic testing. Therapy is based on the clinical presentation and the underlying pathogen.

“…Primary hydatid cyst of the skeletal muscle is rare, with a reported prevalence of 0.5–4.7%. The sites of FNA in 11 cases of hydatid cysts reported by Sinan et al were liver (7 cases), kidney (1 case), retroperitoneum (1 case), abdominal wall (1 case), and back of neck (1 case). Of the 8 cases of hydatid disease described by Das et al, the sites of FNA were liver (6 cases), lung (1 case) and mediastinum (1 case).…”

“… Primary hydatid disease of the skeletal muscle without systemic involvement is rare. Fine‐needle aspiration (FNA) has been utilized as a diagnostic tool for Hydatid cyst as revealed from the reports based on a series of cases from various sites and numerous isolated case reports. The present case was a primary hydatid cyst of the left supraspinatus muscle in an Indian woman living in Kuwait, which was clinically diagnosed as a soft tissue tumor.…”

Primary hydatid disease of the skeletal muscle without systemic involvement is rare. The purpose of this report is to document the novel clinical presentation and the interesting facets of fine-needle aspiration in a case of hydatid disease. It was a case of primary hydatid cyst of the left supraspinatus muscle in an Indian woman living in Kuwait, which was clinically diagnosed as a lipoma. Fine-needle aspiration (FNA) yielded 2 ml of clear fluid with white particulate material. The cytocentrifuged smears prepared from the aspirated fluid showed many scolices, occasional laminated cyst wall fragments and numerous hooklets. The laminated cyst wall and scolices were PAS positive. Trichrome staining imparted a demon-head-like appearance to the scolices. The cytodiagnosis of hydatid cyst was corroborated by histopathological examination of an excised whitish membrane and an irregular cystic fragment, which showed parallel laminations without germinal layer, and skeletal muscle with granulomas and a dense eosinophilic infiltration, respectively. Quantitative serological (indirect hemagglutination) test on blood sample collected 9 days after the excision of the cyst showed insignificant antibody titer to Echinococcus sp. and after 6 weeks the antibodies were completely absent. CT scan of the chest and abdomen performed 7 weeks after removal of cyst showed no evidence of visceral hydatid cyst.

“…In extensive literature search on primary intermuscular HC we could retrieve only three cases. [8][9][10] Muscular HC is diagnosed by using the symptoms and the imaging studies like plain X-rays, US, CT and more recently MR imaging. 8,9 Symptoms can arise from a mass effect or from the complications of the cyst.…”

ABSTRACTthe cases in endemic populations. These cysts appear as slow-growing masses of the soft tissue, sometimes with infl ammatory signs and fi stulization. [1][2][3] In this report, we present imaging fi ndings [ultrasonography (US), computed tomography (CT), and magnetic resonance (MR) imaging] of three cases with various patterns of primary muscular HC. CasesCase 1 A 65-year old man was admitted to our surgery clinic because of a cystic mass within his left thigh musculature. He had realized a progressively growing mass in his left thigh for three years. He was living in a village and had contact with both sheep and dogs since his childhood. There was no history of trauma, fever or weight loss. Laboratory results showed an erythrocyte sedimentation rate of 12 mm/h (Westergren) and a total leukocyte count of 7,000/mm 3 . A hemaglutination inhibition test revealed that the titer of antibodies to Echinococcus was 1:165. Physical examination revealed a diffuse, non-tender cystic swelling occupying nearly the entire anterior aspect of the thigh with the rigidity of the muscles. Chest X-ray was normal. Abdominal US revealed no abnormality. US and CT examinations were performed. US examination showed a 5 x 4 cm mass composed of multiple thin-walled cysts (Fig. 1a). These clusters of cysts were localized between the femur and vastus muscles, with no involvement of the muscle or bone. No calcifi cations were present. CT scan demonstrated the cystic structure close to vastus muscles (medius, intermedius, lateralis) (Fig. 1b). The lesion was defi ned as a type-II HC according to the Gharbi classifi cation.
