What are the signs and symptoms of Camurati-Engelmann disease?

People with Camurati-Engelmann disease have increased bone density, particularly affecting the long bones of the arms and legs (tibia, femur, humerus, ulna, radius). In some cases, the skull and hip bones are also affected. The thickened bones can lead to pain in the arms and legs, a waddling walk, muscle weakness, and extreme tiredness. An increase in the density of the skull results in increased pressure on the brain and can cause a variety of neurological problems, including headaches, hearing loss, vision problems, dizziness (vertigo), ringing in the ears (tinnitus), and facial paralysis. The added pressure that thickened bones put on the muscular and skeletal systems can cause abnormal curvature of the spine (scoliosis), joint deformities (contractures), knock knees, and flat feet (pes planus). Other features of Camurati-Engelmann disease include abnormally long limbs in proportion to height, a decrease in muscle mass and body fat, and delayed puberty.[1][2] In the most severe cases, the mandibula (jaw), vertebrae, thoracic cage, shoulder girdle, and carpal (hands, wrist) and tarsal (foot, ankle) bones are involved.[3]

Radiographically (on X-ray), the shafts of long bones show symmetric and progressive widening and malformation (diaphyseal dysplasia). Vascular (Raynaud's phenomenon) and hematological (anemia, leukopenia (low level of white blood cells), increased erythrocyte sedimentation rate) features and hepatosplenomegaly are commonly associated with the disease.[2][3][4]

The age at which affected individuals first experience symptoms varies greatly; however, most people with this condition develop pain or weakness by adolescence.[1]

The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature.

The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined.

Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
