Hypoplasia Pectoralis Muscle (Funnel Chest)

peex_12a_n.jpg and peex_12b_n.jpg: Semi-oblique view and frontal view of a 16-year-old boy with a depression deformity. The funnel chest is deep and rather narrow. There is an underdevelopment of the right hemithorax and a hypoplasia of the right major pectoralis muscle. Especially in this case the right arm and hand must be examined closely for a possible Poland syndrome.
