Cerebral cavernous malformation (large)

Case contributed by A.Prof Frank Gaillard

Presentation

Long standing epilepsy

Patient Data

Age: 45 years
Gender: Male

MRI brain

Modality: MRI

Within the left occipital pole is a 32 x 36 x 38 mm lesion with a complete surrounding haemosiderin ring, and heterogeneous signal including regions of intrinsic T1 signal. The features are characteristic of a large cavernous malformation. There is no surrounding oedema to suggest recent haemorrhage. No abnormal flow voids or vessels are demonstrated to suggest an associated vascular malformation (e.g. developmental venous anomaly).

A small (7mm) region of susceptibility induce signal loss only appreciable on susceptibility weighted imaging involves the posterior inferior aspect of the left thalamus. This is not clearly visible on other sequences but could represent a second much smaller cavernous malformation, or a small capillary telangiectasia.
