Reveal Findings

CR – Multiple ovoid and pyramidal lucent osseous defects some with expansion and cortical thinning, numerous lobulated soft tissue tumefactions, and numerous phleboliths.

Reveal Discussion

The mutant receptor PTH/PTHrP type 1 is found in the enchondromatous tissue activating the Hedgehog signaling and enchodromatous growth. Maffucci syndrome is enchondromatosis with angiomatosis.

Malignant degeneration occurs in approximately 30%, usually in adulthood, and is more common in Maffucci syndrome. Additionally, there is a higher incidence of extraosseous tumors (usually brain and ovary).

Maffucci syndrome is often confused with Ollier disease. Both have enchondromatosis. Ollier disease has been used to describe unilateral enchondromatosis whereas Maffucci syndrome is enchondromatosis with angiomata.
