Contribution of Imaging in the Hydatid Cyst of Soft Tissues in the Thigh: A Case Report and Literature Review

Abstract

Hydatid cysts in soft tissues remain a rare occurrence, even in endemic regions. This study underscores the crucial importance of imaging modalities for positive diagnosis and topography, providing optimal guidance for effective management strategies. In this article, we present a case of soft tissue hydatidosis in the thigh, directly explored through magnetic resonance imaging (MRI), complemented by soft tissue ultrasound. The observed mass contained vesicles, localized in the thigh. The diagnosis of hydatidosis suggested by ultrasound was confirmed by MRI. A curative surgical intervention was performed on our patient. The diagnosis of soft tissue hydatidosis can be established when ultrasound and/or MRI reveal a multivesicular appearance. MRI proves to be the most useful imaging modality in cases of atypical or pseudo-solid lesions. The peri-cystic enhancement serves as an indicative feature of soft tissue hydatidosis compared to other locations. The study emphasizes the rarity of muscular localization of hydatid cysts and highlights the crucial importance of radiological, surgical, and preventive diagnostic approaches in managing this pathology. The heightened sensitivity of MRI in cases of atypical ultrasound features underscores its central role in the contemporary management of this complex condition, enhancing both diagnostic precision and treatment planning.
