Musculature from 198 Canadian cattle with suspected lesions of eosinophilic myositis were examined histologically and by pepsin digestion. Sera from 51 of the 198 animals were also examined by enzyme-linked immunosorbent assay (ELISA) for anti-Trichinella antibodies. Viable larvae of Trichinella were not recovered from any of the cattle but one animal from Ontario tested positive for anti-Trichinella antibodies. Histologically, focal and/or diffuse eosinophilic myositis lesions were observed in 149 (75.2%) of the animals studied. Other conditions identified were sarcocystiosis, abscesses, cysticercosis, steatosis, fibrosis, granuloma, lymphosarcoma and necrosis. Sarcocystiosis was identified in 105 of the 198 animals in both normal and affected musculature. The study indicates that trichinosis is not a primary cause of eosinophilic myositis in cattle.

We report the first case of diffused cysticercosis combined with epilepsy, myositis and confusional syndrome in Benin. In the absence of tomodensitometric exploration, the patient was treated with success by praziquantel and corticosteroids. This implies the existence of a human focus of cysticercosis in Benin.

Cystic lesions of the extraocular muscles (EOMs) are uncommon. Six patients with a cystic lesion in an extraocular muscle, as observed by computerized tomography (CT) scanning, were retrospectively identified from the practice of one of the authors (G.C.S.), and their clinical course was reviewed. All the patients were treated initially with oral corticosteroids. Those who did not respond to this therapy underwent surgical exploration. Four patients demonstrated complete resolution of clinical signs and symptoms with oral steroid therapy. Posttreatment CT scans performed in two of these patients showed resolution of the cystic lesion with residual muscle thickening in one. The two patients not responding to steroids underwent surgical excision and histopathology confirmed the diagnosis of cysticercosis. Cysticercosis is a previously reported cause of a cystic lesion in an EOM. To the best of our knowledge, cystic lesions of the EOMs resolving with steroids have not been previously reported. Response to oral steroids in four of our patients is suggestive of myositis with a cystic change in the muscle. We recommend a trial of oral steroid therapy in patients with a cystic EOM lesion before surgical exploration is performed.

Cysticercosis, the infestation with the encysted larval stage of Taenia solium, is increasingly recognized as a major problem in most countries in Latin America, Asia, and Africa, involving mainly the central nervous system. Muscle involvement is also common, although it usually remains asymptomatic. We describe a case of disseminated muscular cysticercosis followed by myositis (fever, diffuse myalgia, weakness of the lower limbs, and inflammatory reaction around dying cysticerci) induced by praziquantel therapy, an event not described previously.

Infectious myopathies are rare acquired affections which have, generally, a good prognostic. Many types of viral infections can cause transient inflammatory myopathies. HIV myopathy may be present early in the HIV infection, but more often it is a complication of fully developed AIDS. Influenza virus myositis tend to be more severe in adults than in children. Group B coxsackie virus has been isolated from striated muscle of patients with epidemic myalgia. Parasitic infections of muscle include trichinosis, toxoplasmosis, and cysticercosis. Trichinosis is the most frequent parasitic myositis. The ocular, lingual or pharyngeal weakness and/or hypereosinophilia suggest the diagnosis. Pyomyositis, is a located zone of suppuration of muscle due to staphylococcus in 90% of the cases. It is a common occurrence in tropical climates, but has been recognized increasingly in temperate climates.

Cysticercosis is a common ophthalmic parasitosis wherein humans are the intermediate hosts in the life cycle of the tape worm Taenia solium. While intraocular cysticercosis is more common and is more readily diagnosed clinically, recognition of extraocular cysticercosis needs supplementary imaging. Computed tomography (CT) and magnetic resonance imaging (MRI) have been extensively used to diagnose and characterize neurocysticercosis. Since the orbit is easily accessible to ultrasonography (USG), we evaluated its role in the diagnosis and management of extraocular cysticercosis. Serial A- and B- scan ultrasonograms from 24 patients with extraocular cysticercosis were analyzed to determine features at various stages of evolution of the lesion and an attempt was made to classify the lesion on this basis. Of 24 patients, 23 had a cyst clearly demonstrable by USG: 22 within or attached to an extraocular muscle (with or without myositis) and one free in the orbit. One patient had an optic nerve cyst not detected by USG but by CT scan. Cysts at various stages of evolution were found - viable, degenerating and inactive. The therapeutic response of the cyst to treatment with oral albendazole could be effectively studied and monitored by sequential USG. Orbital ultrasound is a practical, precise and cost-effective imaging modality to diagnose, manage and monitor extraocular cysticercosis, although it can not completely replace CT and MRI.

In this study, we described the morphological features and unusual presentations of hydatidosis, fasciolosis, and eosinophilic myositis caused by Sarcocystis species diagnosed at the slaughterhouse lines. Twenty-seven samples of atypical parasitic lesions from distinct cattle were evaluated, of which 12 corresponded to hydatidosis, 11 to fasciolosis, and 4 to eosinophilic sarcocystosis. Hydatid cysts were observed mainly in the heart, with all cases involving the left ventricle. Fasciolosis lesions involved mainly the lungs, and were characterized by a focal nodular elevated area involving the edges of the lobes. Intralesional trematodes were observed in three cases. Sarcocystosis lesions were observed in four cases, and lesions were primarily located in the skeletal and cardiac muscles. Grossly, they presented as focal or focally extensive streaks, patches, or numerous nodules that were greenish to mildly yellowish. Histologically, all the cases had intralesional ruptured cysts of Sarcocystis that were associated with severe eosinophilic myositis and myocarditis. Parasitic lesions in atypical locations and/or with aberrant responses should be promptly identified because it may mistakenly diagnosed as other potentially zoonotic diseases, such as cysticercosis and tuberculosis.
