Abstract
Intraosseous ganglion is rarely associated with clinical symptoms because instances of extraosseous extensions are rare; the periosteum and the cortex of the bone represent a substantial physical barrier for intraosseous extensions of soft tissue lesions to intrude into bone. However, we observed a case of a symptomatic intraosseous ganglion located in the articular capsule of the hip in the inferomedial femoral neck. A 21-year-old woman complained of persistent mild pain and discomfort in the left groin for 18 months. Further, she complained about involuntary movements such as external rotation of the hip during full flexion and adduction and inability to kneel down, as well as discomfort during exercise such as yoga. Radiography and computed tomography implied the presence of an intraosseous ganglion in the inferomedial femoral neck. Using an image intensifier, we excised the lesion arthroscopically. The patient¡¯s symptoms resolved immediately after surgery. This report describes a case of femoroacetabular impingement caused by an intraosseous ganglion in the femoral neck and evaluates the advantages of arthroscopic procedures for the surgical management of this lesion.
