The Appearance of Maffucci Syndrome on 18F-FDG PET/CT

Area of Science:

• Medical Genetics
• Oncology
• Radiology

Background:

• Maffucci syndrome is a rare genetic disorder characterized by the development of multiple enchondromas (benign cartilage tumors) and hemangiomas (benign vascular tumors).
• The syndrome affects fewer than 200 individuals in the United States, highlighting its rarity.
• A significant concern in Maffucci syndrome is the high propensity for malignant transformation of the enchondromas.

Observation:

• Patients with Maffucci syndrome exhibit a notable predisposition to developing cancerous changes within their enchondromas.
• Early detection of these neoplastic changes is critical for timely intervention and improved patient outcomes.
• Radiological imaging plays a pivotal role in monitoring disease progression and identifying suspicious lesions.

Findings:

• Positron Emission Tomography/Computed Tomography (PET/CT) has demonstrated significant utility in the detection of neoplastic changes associated with Maffucci syndrome.
• PET/CT can help differentiate between benign enchondromas and malignant lesions, aiding in diagnosis and treatment planning.
• The metabolic activity assessed by PET/CT can serve as an early indicator of malignant transformation.

Implications:

• The findings underscore the importance of incorporating regular PET/CT surveillance into the management of Maffucci syndrome patients.
• Improved detection of neoplastic changes can lead to earlier diagnosis and treatment of associated cancers, potentially improving prognosis.
• This highlights the value of advanced imaging techniques in managing rare genetic disorders with high oncological risk.
