Abstract
Ganglion cyst of the hip is rare. This case report describes a large ganglion cyst in a 44-year-old woman with hip dysplasia. She experienced mild right groin pain after prolonged activity. Physical examination revealed a large soft mass in her right inguinal region. No obvious evidence of infection was noted. Radiographic evaluation of her right hip revealed evidence of severe hip dysplasia. Magnetic resonance imaging revealed the mass to have signal characteristics similar to water. It was diagnosed as ganglion cyst. Periacetabular osteotomy was performed for hip dyaplasia. The mass was covered by pseudocapsule and filled with clear mucinous fluid. Further dissection revealed a typical stalk arising from the hip capsule. Histologic examination showed a fibrous connective tissue wall with no distinct cellular lining. Diagnosis of ganglion cyst should be considered when patients present inguinal mass and hip dysplasia.
