Abstract:
Meningiomas-en-plaques (MEP) are characterized by an area of hyperostosis and constitute a diagnostic challenge, especially when associated with other underlying conditions, and may mimic other clinical conditions. We present a case of a large MEP, which was an incidental finding on a scintigraphy study of a patient with prostate adenocarcinoma, this finding being histologically confirmed. In regards to the case, we discuss the utility of the bone scintigraphy (BS) in relationship to other imaging modalities.
Insights
Meningiomas-en-plaques (MEP) are a type of hyperostotic lesion that can mimic other conditions. Bone scintigraphy incidentally detected a large MEP in a patient with prostate cancer, confirmed by histology.
Area of Science:
- Neuro-oncology
- Radiology
Background:
- Meningiomas-en-plaques (MEP) present diagnostic challenges due to hyperostosis and potential mimicry of other conditions.
- MEP diagnosis can be complicated when co-occurring with other pathologies.
Observation:
- A large meningioma-en-plaque was incidentally discovered during bone scintigraphy for prostate adenocarcinoma.
- The patient had a co-existing diagnosis of prostate adenocarcinoma.
Findings:
- Histological confirmation of the incidentally found meningioma-en-plaque.
- Bone scintigraphy identified a hyperostotic lesion suggestive of MEP.
Implications:
- This case highlights the utility of bone scintigraphy in detecting MEP, even as an incidental finding.
- Discussion on the comparative value of bone scintigraphy versus other imaging modalities for MEP diagnosis.
