Overview
CT scan may be helpful in the diagnosis of neurofibroma.
CT Scan
- CT scan may be helpful in the diagnosis of neurofibroma.
- Findings on CT scan suggestive of neurofibroma include:[1][2]
- Well-defined, round or oval hypodense mass
- Has an attenuation value of 20–25 HU on nonenhanced scans and 30–50 HU after contrast material administration
- Best imaging features for diagnosis is a fusiform mass, which represents the nerve entering and exiting the tumor
- Low attenuation is attributed to:
- High lipid or water content within the mucinous matrix
- Entrapment of perineural adipose tissue
- Cystic degeneration (less often)
