Overview
CT findings associated with pleomorphic adenoma include homogeneous attenuation and prominent enhancement if the tumor is small and heterogeneous enhancement and foci of necrosis, haemorrhage and even delayed enhancement if the tumor is large.
CT scan
- CT scan is the first imaging modality of choice for pleomorphic adenoma.[1]
- It helps in identifying the tumor location and also its extension.
- When the tumor is small it shows homogeneous attenuation and prominent enhancement.
- When the tumor is large they can be heterogeneous with probably less enhancement, foci of necrosis, haemorrhage and possible delayed enhancement.[2]
- Small regions of calcification are also common.
