Case report of a primary multiloculate muscular cystic hydatidosis

Abstract

Hydatidosis is a zoonosis caused by the ingestion of Echinococcus granulosus eggs, released though the feces, from infected dogs to humans. Primary localization is mostly hepatic and/or pulmonary, whereas muscular involvement is very rare, even more so in muscular striated tissue. This is the report of a case of a primary intramuscular hydatid cyst in a 79-year-old woman who presented with a 3-year history of a painful lump in her proximal medial left thigh. The authors document the exceptional giant dimensions of the cyst, which have not previously been reported in a case of striated muscular hydatid disease.

Secondary myopathy due to systemic diseases

“…In the tropics, visceral larva migrans (toxocarosis) may manifest as tropical pyomyositis requiring repeated debridement . Hydatid cysts from infestation with Echinococcus may rarely occur in a single muscle as the initial manifestation . Most commonly, liver and lung are affected .…”

“…Hydatid cysts from infestation with Echinococcus may rarely occur in a single muscle as the initial manifestation . Most commonly, liver and lung are affected . Hydatid cysts of the muscle have been occasionally observed in patients with primary muscle disease .…”

Primary Musculoskeletal Hydatid Cyst of the Thigh: Diagnostic and Curative Challenge for an Unusual Localization

“…Possible differential diagnoses include lipoma, calcified hematoma, cold abscess or soft tissue tumour. Musculoskeletal echinococcosis should always be suspected in patients originating from endemic regions (1,5,6,14).…”

Unusual Localization and Presentation of Nonvisceral Hydatid Cysts: Review Article

“…Case V was in a 34 year old woman with a 4x3x2 cm HC in the gastrocnemius muscle. Notarnicola et al (2009) reported a case of primary intramuscular HC in a 79 year old woman who presented with a 3 year history of a painful lump in her proximal left thigh. They documented exceptional giant dimensions of the cyst which was not previously reported in a case of striated muscular HD.…”
