Early complications associated with glioma therapy are common and may seriously aggravate the patient’s condition. On the other hand, little is known about the late effects of glioma treatment. The case is presented of a 58-year-old woman admitted to hospital with suspected brain tumor recurrence. The patient had been diagnosed 3 years earlier with glioblastoma multiforme. On admission, the patient presented dysarthria, central paresis of nerve VII and left limb flaccid paralysis, which led to the suspicion of tumour regrowth. MR brain scans performed 1 hour after symptom onset were inconclusive. However, MR images acquired 72 hours after admission revealed a picture of fresh vascular, ischemic lesion on the right side of the posterior part of the lenticular nucleus. Physicians should be aware that the risk of brain infarct may be increased in long-term survivals with brain tumours.
