Findings and procedure details
All 13 patients underwent emergency MRI investigation in sequences to accept standard brain imaging. EEG were carried out in all cases also.
Among these patients neurological symptoms were: hemiparesis -5/13, seizures and alteration of consciousness-7/13, headache-1/13.
Hyponatremia and hypocalcemia were not revealed in all 7 cases of seizures. Three patients were diagnosed with ischemic stroke (figure 1), but in the reassessment of MR studies in 2 of them the diagnosis of stroke was changed: in 1 case was stroke-like leukoencephalopathy (figure 2,5), in the other case - a combined recurrence of ALL. Posterior reversible leukoencephalopathy (figure 3) was diagnosed in 4 cases. Toxic leukoencephalopathy (figure 4) after the therapy was seen in 5 patients. Stroke-like migraine attacks after radiation therapy syndrome was noticed once. All cases we could observe during relevant treatment.
