Hemihypertrophy is usually diagnosed at birth or in childhood depending on patient's growth pattern. Diagnosis is essential, as idiopathic hemihypertrophy is associated with a heightened risk for developing embryonal tumors in childhood (most commonly Wilms tumor and hepatoblastoma).
Treatment is aimed at handling functional and cosmetic issues. Surgery is usually reserved for patients with length discrepancies over 4 cm and consists of shortening or lengthening the affected area(s). Nonsurgical orthopedic treatment options such as corrective shoe lifts are available.
