Primary Muscular Cystic Echinococcosis Disease: A Case Report and Review of the Literature

Abstract

Cystic echinococcosis is a zoonotic disease that arises from the parasite called Echinococcus granulosus, which has an isolated primary muscle involvement. The clinical presentation of the disease is very similar to that of lipomas. In endemic regions, such as Türkiye, even if the physical examination findings are consistent with lipoma, primary muscular cystic echinococcosis disease should be considered in the differential diagnosis of soft tissue masses. In this case report, we present a rare case of primary muscular cystic echinococcosis that was diagnosed by histopathological examination who was admitted to our clinic with a mass in the left arm which was diagnosed as lipoma preoperatively, and which caused strong suspicion of cytic echinococcosis during the operation under general anesthesia.

Primer Musküler Kistik Ekinokokkoz Hastalığı: Olgu Sunumu ve Literatürün Gözden Geçirilmesi

Abstract

Kistik ekinokokkoz, Echinococcus granulosus adlı parazitin neden olduğu zoonotik bir hastalık olup, bu hastalığın izole primer kas tutulumu ile giden bir formu da mevcuttur. Bu hastalığın kliniği yumuşak doku kitlelerinden özellikle lipomlar ile oldukça benzerdir. Fizik muayene bulguları lipomla uyumlu olsa bile Türkiye gibi ekinokokkoz hastalığının endemik olduğu bölgelerde yumuşak doku kitlelerinin ayırıcı tanısında mutlaka primer musküler kistik ekinokokkoz akla gelmelidir. Bu olgu sunumunda kliniğimize sol kolda kitle ile başvuran ve lipom ön tanısı ile genel anestezi ile eksizyon yapılırken, kistik ekinokokkozdan şüphelenilmesi üzerine yapılan histopatolojik incelemede primer musküler kistik ekinokokkoz tanısı konulmuş nadir görülen bir olgu sunulmaktadır.
