The hypodense meningioma: report of two cases
Neuroradiology
|January 1, 1978
Abstract:
Cystic or necrotic hypodense areas are occasionally seen within meningiomas on CT scans. Two diffusely hypodense endotheliomatous meningiomas are reported. The low density was due to a microcystic structure, which caused a spongy appearance and consistency.
Insights
Hypodense meningiomas, tumors of the brain lining, can appear cystic or necrotic on CT scans. This study identified a microcystic structure as the cause of this unusual low density in two cases.
Area of Science:
- Neuropathology
- Neuroradiology
- Oncology
Background:
- Meningiomas are typically dense tumors of the meninges.
- Hypodense areas within meningiomas on CT scans are uncommon findings.
Observation:
- This report details two cases of endotheliomatous meningiomas exhibiting diffuse hypodensity.
- These tumors presented with cystic or necrotic-appearing areas on computed tomography (CT).
Findings:
- The observed low density in these meningiomas was attributed to a distinct microcystic structure.
- This microcystic architecture resulted in a macroscopic spongy appearance and consistency of the tumor tissue.
Implications:
- Understanding the imaging characteristics of meningiomas, including rare presentations like diffuse hypodensity, is crucial for accurate diagnosis.
- The microcystic nature may influence surgical planning and prognosis for specific meningioma subtypes.
