Cerebral metastasis - solitary

Case contributed by A.Prof Frank Gaillard

Presentation

Right sided weakness.

Patient Data

Age: 70 years
Gender: Female
Modality: CT

A 2cm rounded mass is present in the post-central gyrus, which is iso-dense to cortex pre-contrast and demonstrates homogeneous contrast enhancement. It is located at the grey-white matter interface and is surrounded by extensive vasogenic oedema, which exerts significant mass effect. 

Modality: CT

Following the administration of contrast the mass demonstrates relatively vivid enhancement. It remains an isolated abnormality.

Modality: Annotated image

The enhancing mass ( * ) is surrounded by vasogenic oedema (blue dotted line) which is confined to the white matter. 

Case Discussion

Although typically we think of multiplicity as being the hallmark of cerebral metastases, a large number are seemingly solitary at the time of diagnosis.  Thus metastatic disease needs to be entertained in the differential of a solitary cerebral mass. 

In this case the patient had a known history of metastatic colorectal carcinoma.
