Abstract
Eosinophilic gastroenteritis (EG) is a rare, distinct clinical entity, and EG associated with eosinophilic cystitis (EC) is extremely rare and has not been well documented. Here, we report two cases of EG and coexistent EC along with findings from computed tomography (CT) and magnetic resonance imaging (MRI). An 18-year-old male with a history of hematuria, urgency and occasional urodynia for two weeks and a 34-year-old male with a history of abdominal distention for one week were admitted to our hospital. Abdominal contrast-enhanced CT in both patients revealed wall thickening in different parts of the gastrointestinal tract with inhomogeneous reinforcement, coexistent with local or diffuse bladder wall thickening with progressive enhancement, and also showed that the bladder mucosal lining was nondestructive. Pelvic MRI showed that the local or diffuse thickened bladder wall was iso-intense on T1-weighted images, hypo-intense on T2-weighted images, and slightly restricted on diffusion weighted imaging (DWI) in one case. After therapy, the thickened wall of the gastrointestinal tract and urinary bladder had improved markedly in the two cases. To the best of our knowledge, this is the first report on the radiological imaging of EG and coexistent EC by both CT and MRI and the first with DWI findings.
