Multiple nodular lesions with heterogeneous signal and marked blooming artefact are demonstrated within the pons and right cerebellar hemisphere. A new similar focus that exhibits marked bright T1 signal is demonstrated in the right middle cerebellar peduncle, in keeping with a more recent bleeding cavernoma. The most superior left cerebellar lesion demonstrates bright T1 signal as well. There s a developmental venous abnormality in the right cerebellar hemisphere and brainstem.
Heterogeneous slightly increased signal and swelling within the left anterolateral aspect of the medulla oblongata, consistent with the region of the inferior olivary nucleus. The supratentorial brain parenchyma is unremarkable. Ventricles and basal cisterns are normal in appearance. Right orbital enucleation / prosthetic eye.
Conclusion: new haemorrhagic foci are demonstrated within the right middle cerebellar peduncle and cerebellar hemisphere, with no significant mass effect. Features consistent with hypertrophic olivary degeneration on the left are unchanged.
