Hypertensive Brainstem Encephalopathy Combined with Acute Ischemic Stroke

Posterior reversible encephalopathy syndrome is a clinicoradiological syndrome characterized by a unique reversible pattern on imaging and total regression of clinical symptoms and signs. Hypertensive brainstem encephalopathy (HBE), a brainstem variant of posterior reversible encephalopathy syndrome, is rare. In addition, a concomitant occurrence of acute ischemic stroke and HBE is even more rare. We here report three patients with HBE accompanied by acute cerebral infarction detected by brain magnetic resonance imaging and the importance of initial blood pressure control.

Meningeal Carcinomatosis Presenting with Isolated Pseudotumor Cerebri

A 46-year-old man presented with a progressive headache lasting for 2 weeks. Initial lumbar puncture revealed a pressure of 31 cm H20 and 30 white cells. His symptoms had worsened despite the treatment of intracranial hypertension. Visual field exam showed marked peripheral constriction and the fundus showed marked papilledema. Cytological analysis of cerebrospinal fluid demonstrated positive for metastatic carcinoma. We report a case of a patient with meningeal carcinomatosis who developed isolated intracranial hypertension with papilledema.
