Abstract

Groin lesions can be classified as neoplastic or non-neoplastic. Neoplastic lesions include lipoma, epidermoid cyst, angiomyofibroblastoma-like tumor, liposarcoma, and synovial sarcoma, as well as metastases from lymphoma, neuroendocrine carcinoma, and carcinomas of the lung, breast, urinary bladder, ovary, vulva, and colon. Non-neoplastic lesions include hernias, round ligament varices, endometriosis, Kimura disease, Castleman disease, hematoma, and inflammation. Because the clinical implications and therapeutic strategies for groin lesions vary depending on the cause, the ability to noninvasively differentiate among etiologies is very important. Although there is substantial overlap in ultrasonographic findings across various groin lesions, some ultrasonographic features, along with clinical characteristics, may suggest a specific diagnosis. Familiarity with the ultrasonographic and clinical features of various groin lesions facilitates accurate diagnosis and treatment.
