Introduction

Introduction Bone spot disease is also known as osteoporosis (osteopoikilosis), disseminated agglutination bone disease (osteopathia condensensdisseminata) and spotted bone (spottedbone). Most of the bones on the body have widely spread fine spots, which generally do not produce clinical symptoms, and most of them are accidentally discovered by X-ray examination for other reasons. The disease is best found in the cancellous bone of the tubular bone, the metaphysis of the metaphysis, and also in some flat bones and irregular bone. According to the pathological observation, there are a plurality of gray-white round or elliptical dense small bones in the cancellous bone.

Cause

Cause

Bone spot disease is characterized by multiple sclerosis spots in the bone, mostly scattered. The literature reports are hereditary and familial, extremely rare. Familial onset is autosomal dominant, and one of the parents must be a patient. According to statistics, the number of people in the population is 1 in 10 million. The cause of this disease is not yet known, and it can be seen at any age, and heredity has nothing to do with gender. The reported cases are clearly hereditary. Examination of his immediate family members revealed that the patient's father and grandmother's pelvic X-ray were similar to the patient, and the patient's mother had no relevant lesions.

Bone spot disease occurs in the hand, foot and short bone, the metaphyseal end of the tubular bone, the bone end and the pelvis, scapula and other flat bones, irregular bones, rarely involving the skull, ribs, spine, sternum, clavicle. The lesions are symmetrically distributed on both sides, diffusely multiple, and vary in size, ranging from a few millimeters to 1.5 cm. Most of the morphology is nodular, round, and elliptical, and the closer to the joint, the denser the lesion. A few strips are dense and dense, and the long axis is consistent with the long axis of the bone. The edge is smooth or irregular. The density is closer to the center, and the density of the edge is slightly lighter. In the humerus and shoulder joints, the acetabulum and glenoid joints are centered, and the lesions are arranged radially, and some overlap and merge. The periosteum and articular cartilage are not invaded, the joint surface is smooth, and the gap is well-proportioned. There was no abnormality in the surrounding soft tissue. Wilcom and Pillmore have been divided into three types: spot nodule type, line type, and mixed type according to the different X-ray manifestations of bone spot disease. The disease is a mixed type.

Diagnosis

Differential diagnosis

Stone osteopathy: Stone osteopathy is also known as marble bone, primary fragile bone sclerosis, sclerosing proliferative bone disease and chalk-like bone. It is a rare bone development disorder. It was first discovered by Albers-Schonberg (1904), also known as Albers-schonberg disease. The disease is characterized by the persistence of calcified cartilage, causing extensive bone sclerosis, and the severe case is related to the closure of the medullary cavity, causing severe anemia. The disease is often familial, and the vast majority of cases are recessive.

Central calcification: central chondrosarcoma can be characterized by blurred border osteolysis, with or without cortical bone disruption. Because cartilage tends to be calcified and ossified, X-ray areas can appear in the tumor, and calcification often occurs in cartilage lobule There is no structure around. It is characterized by irregular hazy particles, nodules or X-ray opaque rings.
