“…The problem of this situation is that confusion can exist with a space occupying lesion. Patel et al reported the same situation in one case [ 10 ], where a plain head CT imaging revealed the presence of a space occupying lesion and surrounding vasogenic edema in the left occipital lobe. Grey matter around the edema gave the impression of a space occupying lesion.…”

The posterior reversible encephalopathy syndrome (PRES) is a rare clinical-radiological entity well described with typical clinical and radiological manifestations. Atypical presentation, especially in imaging, exists. The authors report here two cases of posterior reversible encephalopathy in which imaging aspects were atypical, mimicking, in the first case, hemorrhagic cerebral metastasis of cholangiocarcinoma and, in the second case, a brain tumor. The diagnosis has been retrospectively rectified due to clinical and radiological outcome.

“…MRI is the gold standard for the diagnosis of PRES and should be performed as soon as possible. Since the first description in 1996,1 several radiological patterns of PRES have been reported,5 including asymmetrical and unilateral variants3 11 or involvement of atypical regions, such as brainstem and cerebellum 12–17. In typical PRES, neuroimaging usually reveals symmetric oedema in the subcortical white matter of parietal–occipital regions.…”

Typical posterior reversible encephalopathy syndrome (PRES) is a clinical-neuroradiological entity characterised by bilateral white matter oedema, which is usually symmetrical and totally reversible in 2–3 weeks. A 46-year-old man presented with a persistent headache and visual blurring in the right eye. On admission, the clinical examination revealed minimal unsteadiness of gait and elevated blood pressure. A brain MRI showed a hyperintense signal on T2-weighted sequences in the whole brainstem, extended to the spinal cord (C2–C6), the left insula and the right cerebellum. When his blood pressure was controlled, his symptoms gradually improved. The follow-up MRI scan at 3 weeks revealed a dramatic regression of the hyperintense lesions on T2-weighted sequences. The differential diagnosis of PRES is very wide, especially in the case of conspicuous brainstem involvement. Treatable causes of white matter oedema should be always kept in mind to avoid misdiagnosis and prevent complications, such as intracranial haemorrhage.
