Abstract
Poland's syndrome comprises a spectrum of chest-wall deformities affecting, to various degrees, the rib cage, the chest-wall muscles, neurovascular structures of the ipsilateral arm and the overlying breast. We present a neonate with features of depressed right chest-wall with no respiratory distress. Computed tomography showed hypolasia of the right pectoralis major muscle, with reduced subcutaneous fat on the ipsilateral side of the chest, with abnormalities of the ribs on the same side but absent upper limb deformities. There is negative history of other family members of being affected.
