Abstract
Multiple osteochondromas were detected during a lower extremity sonographic examination of a child with a palpable mass. An osteochondroma is a benign bone tumor that typically arises from the long bones, especially around the knee. Diagnosis is usually made during adolescence when a mass is palpated. Those affected are typically asymptomatic, but some experience pain, swelling, and possible pseudoaneurysm depending on the size and location of the lesion. Treatment is unnecessary unless symptomatic. Annual monitoring is necessary because a small percentage undergo malignant transformation. Sonography is not the modality of choice when imaging bone tumors, but it is important for sonographers to understand that bony abnormalities can be found in patients referred for evaluation of a palpable mass.
