23-year-old female with cavernous confirmations. Redemonstrated are lesions with susceptibility effect in the left basal ganglia, right anterior temporal lobe, right precentral gyrus, posterior right medulla, left superior cerebellar hemisphere, and at the junction of the left pons and midbrain. The nidus of the left basal ganglia lesion has increased in size (as measured on axial T2 technique), now measuring 8 mm in transverse dimension (previously 5 mm), although there is no associated perilesional edema. The remaining lesions are stable. There are no new lesions and there are no associated developmental venous anomalies. There is no evidence of acute intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Multiple supratentorial and infratentorial subcentimeter lesions are compatible with cavernous malformations. The nidus of the left basal ganglia lesion has increased in size, although there is no associated perilesional edema, thus suggesting interval internal microhemorrhage yet not within an acute time frame. The remaining lesions are stable in appearance and there are no new lesions.
