RESUMEN
Posterior reversible encephalopathy syndrome is a rare syndrome characterized by brain edema and neurological symptoms, often resulting from several drugs. Treatment is based on discontinuation, and diagnosis is thus essential. Only 13 cases of posterior reversible encephalopathy syndrome have been reported in inflammatory bowel diseases, and we present the first after azathioprine in adults. A 56-year-old patient with active ulcerative colitis was found unconscious 5 days after the institution of azathioprine. Right-sided hemiplegia was found after the patient regained consciousness. Magnetic resonance imaging showed altered signal associated with diffusion restriction in the occipital lobe and cerebral vasogenic edema. Complete regression of neurological signs occurred after azathioprine discontinuation.
RESUMEN
Brunner's gland hamartoma (BGH) is an uncommon benign tumor arising from alkaline-based mucin-secreting glands of the duodenum. These lesions are typically discovered incidentally during upper gastrointestinal endoscopy or radiological diagnostics, even though they can eventually lead (in the case of increasing size) to obstructive or hemorrhagic symptoms. We report the case of a 67-year-old Caucasian man with two episodes of melena and epigastric pain during the last month. Esophagogastroduodenoscopy revealed a large pedunculated and eroded polyp inside the antrum with a 2-cm-long stalk arising from the anterior wall of the duodenal bulb. Endoscopic ultrasonography showed a submucosal lesion with homogeneous hyperechoic parietal thickening and some central gaps. The muscularis was undamaged. No lymphadenopathy was observed. We performed an en bloc endoscopic resection of the polyp. The size of the whole piece was approximately 6 × 3 × 2 cm, pseudocapsulated and tough in consistency. In the case presented, the en bloc endoscopic removal was successful despite the size of the tumor.
