Patient went on to have MRI of Lt hip for further evaluation of the area of lucency
This MRI demonstrates a T1 hypointense and T2 hyperintense lesion in the neck of femur anteriorly with surrounding edema. Cortical defect is also noted anteriorly. Extracortical collection (T1 and T2 hypointense) with surrounding rim enhancement is also noted extending through the cortical defect. These findings suggestive of a bone cyst complicated by fracture and hematoma.
Case Discussion
Patient subsequently underwent prophylactic pinning of her left neck of femur. Histology confirmed aneurysmal bone cyst.
