Camurati-Engelmann disease

Camurati-Engelmann disease, also known as progressive diaphyseal dysplasia, is a rare autosomal dominant sclerosing bone dysplasia. It begins in childhood and follows a progressive course.

Common symptoms include extremity pain, muscle weakness, cranial nerve impairment and waddling gait. A small proportion can be asymptomatic. Patients can have hepatosplenomegaly 5.

In a vast majority of cases, it occurs from a defect in the TGFB1 gene. It is due to osteoblastic overactivity.

Tends to be bilateral and symmetrical. Can affect any bone but has a greater predilection for the long bones (femur, tibia, fibula, humerus, ulna and radius). Other common sites include the skull and pelvis.
