Unusual case of mixed sclerosing bone dysplasia in a 3.5-year-old boy.

: The aim of the study is a description of a 3.5-year-old boy with mixed sclerosing bone dysplasia. From boy's birth the shortening of the left upper limb and malfunction of the left elbow joint were observed. Physical examination showed: higher placement of the left shoulder, obligatory outside-rotation position of the left lower limb, mobility limitation of the left: elbow, hip and knee joints. Examinations--including calcium-phosphatic, ionic and hormone metabolism--were normal. Roentgenograms and computer tomography (CT) examination showed a picture typical for melorheostosis in upper left limb and changes typical for osteopathia striata in left hip and left femoral bones. Scintigraphy showed bilateral bigger radiomarker uptake in the left femoral bone and in right humerus, femoral bone and tibia. The above described case is a mixed sclerosing bone dysplasia--coexisting of melorheostosis and osteopathia striata.
