Abstract
Case of a 24-year-old woman presenting due to edema in lower extremities. The patient had had infectious mononucleosis three weeks prior and had medical history of suspicion of Crohn’s disease (CD) (due to a non-specific ileocolitis in a colonoscopy/EnteroRM). No ongoing medication. Laboratory evaluation unveiled hypoproteinemia with severe hypoalbuminemia, no renal abnormalities. A PLE was assumed, with post-infectious or CD being the most likely culprits. Alternative causes were extensively excluded. A videocapsule revealed white-tipped or granular villi, some white nodular villi and diffuse edema of the mucosa, and multiple extensive erosions and superficial ulcers in the jejunum and proximal ileum, not suggestive of CD. A push enteroscopy revealed unspecific histopathology. After incomplete response to enteral nutrition, corticotherapy was initiated resulting in sustained improvement. A follow-up Ileocolonoscopy and double balloon enteroscopy revealed no abnormalities. Six months post-treatment, the patient remains asymptomatic, with unremarkable laboratory results and no need for medication.
