ABSTRACT

Diagnosis: Monostotic Fibrous Dysplasia

History: A 29-year-old man with injury to right shoulder while lifting weights. Clinically diagnosed with rotator cuff biceps tendinitis.

Findings: • Plain film RUE - Endjavascript:void(null);osteal scalloping and lucency within the mid to proximal shaft of the right humerus. • Plain MR of the right shoulder - Multiloculated cystic lesion of proximal humerous with some solid component and associated endosteal remodeling without evidence of cortical breakthru. • MRI of the right humerus w/ contrast - Multifocal, predominantly cystic multiloculated circumscribed bony lesions spare the humeral epiphyses, the largest proximal metaphyseal lesion measuring approximately 5.2 cm in its maximum diameter. The lesions exhibit predominantly peripheral enhancement and a mild increase in central T1 intensity suggesting a proteinaceous/fibrous matrix. No overlying cortical disruption is seen in the setting of grossly stable associated endosteal scalloping. No circumferential soft tissue abnormality is identified.

Ddx: • polyostotic fibrous dysplasia • enchondroma • Other differential diagnoses include: Eosinophilic Granuloma, Fibrous Cortical Defect, Nonossifying Fibroma, Giant Cell Tumor, Neurofibromatosis Type 1, Paget Disease, Hemangioma, Hyperparathyroidism, Metastasis

Dxhow: Characteristic imaging features

Exam: Rotator cuff biceps tendinitis. Incidental note of mid proximal humerus endosteal scalloping on plain film evaluation - Now, referred for evaluation of the right shoulder with MRI.

No MeSH data available.


Internally rotated RUE. Endosteal scalloping and lucency within the mid to proximal shaft of the right humerous. The matrix of the lucency is smooth and relatively homogeneous; classically, this finding is described as a ground-glass appearance.
