CTICasesNeurofibromatosis Type 1
Imaging findings
Chest radiograph shows multiple nodular opacities projecting over both lung fields. Lateral radiograph and chest CT demonstrate that these are entirely cutaneous and subcutaneous neurofibromas on the skin surface. The patient also has a history of MPNST in the lower extremity.
Key takeaways
Cutaneous neurofibromas in patients with NF1 can project over the lungs on a chest radiograph, mimicking metastatic pulmonary nodules. Verification on lateral views or CT is essential.
