Pachydermoperiostosis (Primary Hypertrophic Osteoarthropathy): Case Report

We report a case involving a young male with the complete form of primary hypertrophic osteoarthropathy. He presented with the typical features of the condition: thickening and furrowing of the skin of the forehead and scalp, and digital clubbing of the hands and feet. Plain radiographs of the long bones of the extremities depicted bilateral irregular, shaggy, cortical diaphyseal thickening. T1- and T2-weighted magnetic resonance imaging(MRI) of the femur demonstrated low-signal-intensity cortical thickening. Bone scintigraphy revealed no photon uptake in the long bones.
