Summary
This report details an extremely rare case of cerebral lipomas in a 65-year-old female. The tumors were found with focal cortical dysplasia and unusual angiographic features, prompting discussion on their combined etiology.
Area of Science:
- Neuropathology
- Neuroradiology
- Neuro-oncology
Background:
- Lipomas are benign tumors typically found in the central nervous system.
- Cerebral lipomas, especially on the cortical surface, are exceptionally rare.
- Focal cortical dysplasia is a developmental abnormality associated with epilepsy.
Observation:
- A 65-year-old female presented with extremely rare lipomas on the cerebral surface.
- Tumors were located in an unusual right frontal convexity fissure and beneath the right frontal lobe.
- These lipomas were associated with and surrounded by areas of focal cortical dysplasia.
Findings:
- Angiography demonstrated dilated right anterior cerebral artery branches.
- Associated angiomatous tumor blush was noted.
- The combination of lipomas and cortical dysplasia presented unique diagnostic challenges.
Implications:
- This case highlights the importance of considering rare diagnoses in neuroimaging.
- Understanding the co-occurrence of lipomas and cortical dysplasia may offer insights into developmental brain anomalies.
- Further research into the etiology and management of such complex cases is warranted.
