Abstract :

Introduction: One-third of twins are monozygotic. Of monozygotic twins, 25% of them are mirror images. Mirror-imaging occurs when pathologic conditions are present on opposites sides of the body . There are several reports to date of mirror-image heterotaxy, dentition, branchial arch syndrome, strabismus, and cleft lip/palate. This is the first case report of mirror-image identical twins with opposite hip pain who were found to have small cysts of the femoral head on opposite hips. Methods: Case presentation and review of literature. Results: 38 year-old mirror-image Asian female identical twins presented with hip pain on opposite sides. MRI demonstrated a 4 mm. cyst of the anterior aspect of the left hip, the femoral head and neck junction, with a herniation pit on opposite sides. The right-handed twin had the cyst on the right hip, and the left-handed twin had the cyst on the left hip. Conclusions: Mirror-image pathology in mirror-image monozygotic twins suggests possible cytogenetic factors involved in the etiology of various medical problems. If an identical twin presents with a medical problem, it may be recommended to perform a medical diagnostic work-up on the other twin.
