Symptoms of the chondroblastoma in a child

Typical complaints are joint pain, the intensity of which increases over time. With prolonged course of the tumor, marked lameness, hypotrophy of the soft tissues of the limb, contracture of the joint. Typical localization is the epiphysis and epimetaphysis of long tubular bones.

Diagnostics of the chondroblastoma in a child

On X-rays and CT, an eccentrically located lesion focus with clear boundaries and a tendency to spread to the metaphysis area is revealed in the epiphysis of the tubular bone. The presence of zones of calcification gives the internal structure of the focus a speckled appearance. When scintigraphy, both local hypervascularization (on average 170%) and hyperfixation of the radiopharmaceutical (average 230%) are recorded.
