Abstract:
We present the MRI findings in two patients with "fibro-osseous lesions" involving the central nervous system. A left temporal lobe mass was present in one patient and an extra-axial mass at the skull base in the other. In both cases, calcification was present, with low signal intensity on T1- and T2-weighted images.
Insights
We describe MRI results for two patients with central nervous system fibro-osseous lesions. Both cases showed calcification, appearing as low signal intensity on MRI scans.
Area of Science:
- Neurology
- Radiology
- Pathology
Background:
- Fibro-osseous lesions are rare bone and fibrous tissue growths.
- Central nervous system involvement is uncommon.
- Magnetic Resonance Imaging (MRI) is crucial for diagnosis.
Observation:
- Two patients presented with central nervous system fibro-osseous lesions.
- One patient had a left temporal lobe mass.
- The other patient had an extra-axial mass at the skull base.
Findings:
- Calcification was identified in both cases.
- The calcifications exhibited low signal intensity on T1-weighted MRI sequences.
- Low signal intensity was also observed on T2-weighted MRI sequences.
Implications:
- MRI findings can aid in the diagnosis of CNS fibro-osseous lesions.
- Understanding signal characteristics is key for differentiation.
- Further research may elucidate specific imaging biomarkers.
