title: Ultrasound findings in infantile systemic hyalinosis.
abstract: To describe clinical and ultrasound findings in a patient with infantile systemic hyalinosis (ISH). A 5-month-old boy was evaluated of joint contractures. In addition to clinical and laboratory investigations, an ultrasound of his joints was done and compared to a child with similar age. On examination, a short neck, gingival hyperplasia and papular rash were noted. Joint examination showed painful passive movement, reduced range of motion, and joint contractures in knees, elbows, and small joints of the hands, without any evidence of synovial thickness. Ultrasound of the affected joints showed irregular cortical surface of MCPs and PIP, the presence of osteophytes and bone erosions, increased synovial fluid without evidence of synovial hyperplasia. This is the first report to show evidence of US findings in ISH. Ultrasound findings may help to distinguish ISH from JIA in early stages.
