A 14-year-old girl presented with progressive paraparesis and paresthesia of one-year duration. Magnetic resonance imaging revealed a T6 vertebral hemangioma with epidural compression on the spinal cord. Following angiography and embolization, she underwent dorsal laminectomy and excision of the soft tissue component compressing the cord. In the postoperative period she had rapid worsening of lower limb power and imaging demonstrated an epidural haematoma at the operative site. The patient was taken up for urgent re-exploration and evacuation of haematoma. Postoperatively the patient complained of visual failure, headache and had multiple episodes of seizures. An magnetic resonance imaging brain showed characteristic features of posterior reversible encephalopathy syndrome (PRES) and the patient improved gradually after control of hypertension. This is the first documented case of PRES following spinal cord compression in a patient without any known risk factors. We postulate the possible mechanism involved in its pathogenesis.

Unlabelled: The most frequent cause of nephritic syndrome in the pediatric population is acute post-infectious glomerulonephritis (PIGN). A rare complication is posterior reversible encephalopathy syndrome (PRES), characterized by subcortical vasogenic cerebral edema associated with variable neurological symptoms. The development of autoimmune hemolytic anemia is an atypical clinical presentation.

Background: Observational studies suggest that hypertension affects brain cortical structure. However, the potential causal association has yet to be entirely determined. Thus, we aim to assess the causality between hypertension and abnormal cortical structure.

Background: The defining characteristic of posterior reversible encephalopathy syndrome (PRES) is a reversible, predominantly vasogenic edema of the white matter, particularly affecting the parenchyma supplied by the posterior circulation. PRES is most commonly associated with hypertension. We present a case series of seven normotensive patients diagnosed with cancer who had posterior reversible encephalopathy syndrome.

In surgery for acute type A aortic dissection, controlling bleeding from the posterior wall of the proximal anastomosis is particularly challenging. To address this, we use the "reversed turn-up technique." For the reinforcement of the proximal aortic stump, Teflon felt strips were placed inside and outside the suture line with 4-0 polypropylene continuous transverse mattress sutures, and BioGlue was applied to the false lumen.
