Figure 17. Severe pes equinus. Lateral radiograph of the right foot in a patient aged 17 years shows marked enlargement of the distal tibia and fibula; deformity and abnormal flexion of the calcaneus in the dorsal direction (black arrowhead); enlargement of the distal portion of the proximal phalanx, proximal portion of the distal phalanx, and the sesamoid bones of the first ray (arrows); coarse trabeculation of the enlarged bones; and lobulation of the plantar skin (white arrowheads), a finding that indicates cerebriform connective-tissue nevus.
