ABSTRACT

Diagnosis: Hereditary Multiple Exostoses

History: 19 y.o. man with known problem, referred to Orthopedic Clinic for further management.

Findings: Multiple well-defined pedunculated exophytic lesions project from the metaphyseal region of the distal femur and proximal tibia, oriented away from the left knee joint. There is medullary continuity with the bone of origin. The epiphyses and joints are uninvolved. Well-defined osseous excrescence of the right fibular head which has medullary continuity with the fibula, and very little if any osteoid matrix. The lesion wraps around the tibia posteriorly, and causes deformity of the tibia but no invasion/destruction. Similar lesions are found in the distal tibiae bilaterally, causing deformity of the adjacent fibulae.

Ddx: These imaging findings are diagnostic for Multiple Hereditary Exostoses. For less clear-cut cases, or when only a single lesion is identified, see the TF topic discussion for other diagnostic considerations.

Exam: Multiple hard nodular masses near extremity joints. They are somewhat deep to soft tissues and are non-tender.

No MeSH data available.
