These dense transverse metaphyseal bands are from alternating growth arrest and then growth resumption in this patient with a systemic chronic illness.
Growth arrest lines (or "growth resumption lines") are patterns of parallel sclerotic transverse metaphyseal bands in long bones. The differential for this appearance is long, but after a thorough workup, these lines were thought to be due to the patient's cerebral palsy and multiple lower extremity surgical interventions.
