Primary hydatid cyst in the anterior thigh: Sonographic findings

Abstract

Hydatid cysts rarely involve the musculoskeletal system. We present the case of a 23-year-old man with a primary hydatid cyst between the femur and the quadriceps muscle in his left thigh. No cysts were located in the adjacent femur or quadriceps muscle. Cyst resection with sparing of the surrounding muscles, combined with anthelmintic therapy, was curative. In regions where hydatidosis is endemic, hydatid cysts should be included in the differential diagnosis of any unusual soft-tissue swelling.

An unusual cause of circulatory disorder due to a rare intermuscular hydatid cyst of cruris: A case report

“…Calcifications were not observed by radiography in our case. The use of USG is proposed in muscular HC diagnosis [7,19,21,22] . In USG, unilocular cysts, which contain daughter cysts, echogenic hydatid sand, a floating detached laminated membrane, and multivesicular cysts, may be observed [19,22] .…”

MRI is beneficial in the differential diagnosis of other soft tissue cystic tumors, such as ganglion cyst, seroma, abscess and epidermoid inclusion cyst, and in malignancies located in the soft tissue [19] .…”

“…MRI is beneficial in the differential diagnosis of other soft tissue cystic tumors, such as ganglion cyst, seroma, abscess and epidermoid inclusion cyst, and in malignancies located in the soft tissue [19] . Lesions may generally be observed with a general high signal density in T2-weighed images and low density in T1-weighed images, and low density rim in both T1 and T2-weighed images [11,13,22] . This rim finding is not specific for HC, and it may also be observed in other lesions with a fibrosis capsule or a calcified rim [12] .…”

Ultrasound-assisted musculoskeletal procedures: A practical overview of current literature

“…Ultrasound has been well described as a tool for diagnosis of tissue fluid collections as well as characterization of soft tissue infections [33][34][35] . A brief listing of types of soft tissue infections where ultrasound can be used for diagnosis can be seen in Table 4 [ [33][34][35] .…”

“…A brief listing of types of soft tissue infections where ultrasound can be used for diagnosis can be seen in Table 4 [ [33][34][35] . Additionally, ultrasound can be used to aid in the diagnosis of osteomyelitis, particularly in pediatric cases [36] .…”
